The First-Time Buyer’s Mortgage Journey: A Complete, Practical Guide

Mortgage Process - Main Image
Who this is for

If you are buying your first home and want a clear, end-to-end view of what happens, in what order, and why — this guide is for you.

How to read this

This explains the ideal, logical sequence from first thought to mortgage offer and completion support.
In real life, you might join mid-way, skip a step, or loop back — that’s perfectly normal.
Use the anchor links and checklists to dip into the parts you need most.

Before You Start: What “Good Process” Looks Like
  • A clear picture of how much you can borrow, how much deposit you need, and what the total monthly cost could be.
  • An Agreement in Principle ready to show estate agents so your viewing and offer carry weight.
  • A researched product and term only once a property is agreed, not before.
  • A thorough application-prepping stage so there are fewer surprises later.
  • Prompt responses to lender queries and valuation logistics handled early.
  • A final mortgage offer that matches your illustration, checked for errors.
  • Ongoing rate watch right up to exchange if the lender reduces rates.

Scenario Assessment and Game Plan
Goal:
To answer four key questions with confidence:
  • What is the maximum loan available to you?
  • What deposit is needed and where will it come from?
  • What one-off costs are likely at the start?
  • What will your monthly payments look like under realistic options?

What we capture from you:

  • Employment and income details (including bonuses, overtime, or commissions).
  • If self-employed or a company director — profits, salary, dividends, latest accounts, or SA returns.
  • Credit commitments such as loans, cards, car finance, or student loans.
  • Family situation and foreseeable changes affecting affordability.
  • Deposit source and evidence.
  • Property preferences such as freehold or leasehold, service charges, ground rent, or new-build details.

Our unique approach

We prepare a personalised, dynamic spreadsheet that models:

  • Different property prices and deposits.
  • The impact of term or rate changes.
  • How your affordability and payments shift with each scenario.

This prevents wasted viewings and helps you and your family align on a realistic plan before falling in love with a property outside budget.

Outputs you receive:

  • A clear headline range for purchase price and loan.
  • Estimated upfront costs.
  • Indicative monthly payments under a few realistic setups.
  • A summary of the best-case pathway, subject to standard checks.

Mortgage Journey

Agreement in Principle: Confidence for Viewings and Offers
What it is:

A lender’s non-binding confirmation that, based on declared information, your credit profile and circumstances appear acceptable for borrowing up to a stated limit and deposit.

What it is not:

  • Not a product choice or rate lock.
  • Not a full underwrite.
  • Does not require you to evidence income or deposit to the lender at that stage.

Possible outcomes:

  • Accepted for the requested loan and deposit.
  • Accepted but for a lower loan or higher deposit.
  • Referred for manual review.
  • Declined.

Why it matters:

Estate agents often ask for an AIP before viewings or when you make an offer. It demonstrates you’re financially prepared and serious about buying.

Tip:

We usually obtain the AIP at the most conservative deposit level you’re comfortable with. If you later choose to put in a larger deposit, that’s an easy adjustment.

Full Application: Only After Your Offer Is Accepted
When to choose products:

Only after the property and price are agreed. Before that, we show you ranges and examples — not specific products.
Once an offer is accepted, we refresh your spreadsheet and review:

  • Product style (fixed, tracker, discount).
  • Fixed period (two or five years, and whether flexibility is important).
  • Term, affordability, and how it affects long-term cost.
  • Fees and whether adding or paying upfront makes sense.
  • Leasehold and property-type considerations.

The key document you receive:

A detailed Mortgage Illustration that outlines your rate, fees, term, payments, and deposit.
This forms the foundation of the final mortgage offer, assuming there are no material changes.

The key document you receive

Application-Prepping: The Extra Work That Saves Time Later
We resolve complexity before submission to minimise delays. Expect us to check lender criteria thoroughly and gather complete supporting evidence up-front, including:
  • ID and address verification.
  • Income documents: latest payslips, P60s for the last two years, and employment letter if required; or SA302s (Tax Calculations), Tax Year Overviews, company accounts, and accountant references for business owners.
  • Bank statements and explanations for unusual transactions.
  • Evidence of all credit commitments and deposit source.
  • Property details (lease, ground rent, new build warranty, etc.)

Why this matters:

It reduces back-and-forth, makes underwriting smoother, and surfaces deal-breakers early when there’s still time to adapt.

How Long Each Step Takes

After Submission: Underwriting and Valuation
Lenders typically run these in parallel, though some prefer to finish underwriting before instructing a valuation, especially in specific or complex cases.
Underwriting — what to expect:
  • The case manager checks that all documents match the application.
  • Queries are common; some cases complete in a single round, while others require several iterations depending on complexity.
  • The lender focuses on identity, affordability, credit conduct, and how your deposit is sourced and evidenced.

Valuation — types, triggers and outcomes:

At this point, the lender instructs a valuation to confirm that the property is suitable security for the mortgage and that its value matches the agreed price.
You may not always see a valuer in person — sometimes it’s done digitally or from outside the property.

Property Valuation

The infographic above shows the three main valuation methods and the possible outcomes.
Here’s how to read it in context:

  • If the valuation comes back at the agreed price, the process moves smoothly to mortgage offer.
  • If it’s lower than the purchase price (a “down valuation”), we’ll discuss options — renegotiating the price, increasing your deposit, or exploring alternative lenders.
  • If the property is deemed unsuitable as security, this usually points to structural or legal issues. In such cases, we’ll reassess whether another lender or property is more appropriate.

If you’d like to understand the different types of property surveys and when each is recommended — for example, a RICS Level 2 (Homebuyer) or Level 3 (Building) report — read our detailed guide:When to Get a Property Survey

Mortgage Offer: Final Approval Before the Legal Stage
When the lender issues your mortgage offer, we:
  • Review it thoroughly to ensure it matches the illustration and key details.
  • Flag and correct any discrepancies with the lender.
  • Share the confirmed copy with you and your solicitor.
  • Update the estate agent that the offer is in place (without sharing private documents).

From this point, the legal work drives the timeline — searches, enquiries, and exchange.
We remain engaged until completion and monitor for potential rate reductions that may benefit you.

Rate Watch Between Offer and Exchange
If the lender reduces their rate and switching is practical before exchange, we assess whether it’s worthwhile and help you move to the better deal where feasible.

Your Role in Keeping Things Smooth
  • Provide complete documents promptly in the requested format.
  • Keep us updated on any job, income, or deposit changes.
  • Respond quickly to emails or document requests.
  • Facilitate access for surveyors and solicitor ID checks without delay.

What Happens After the Mortgage Offer
Your solicitor now takes the lead — handling searches, enquiries, exchange of contracts, and completion.
We remain available to coordinate lender conditions, monitor rates, and keep all parties aligned.

Frequently Asked Questions

Yes — we’ll need your solicitor’s details before we submit your full mortgage application.
Having a solicitor in place helps avoid delays once the mortgage offer is issued and ensures your legal work can start promptly.
We’re happy to share a quote from one of the solicitors we work closely with for you to consider — entirely without pressure or obligation.

Yes, most lenders are comfortable with gifted deposits as long as there’s a formal letter confirming it’s a genuine gift, not a loan.
We’ll guide you and your family through what’s required so that the paperwork is exactly as lenders expect.

That’s absolutely fine — just let us know as soon as you can.
A change of job can affect how a lender assesses your application, but not always negatively.
We’ll review the new details, check lender criteria, and help you decide the best way forward without losing momentum.

Often yes, if there’s enough time before exchange and if the lender allows product switches.
We’ll assess whether it makes sense financially and, where worthwhile, help you move to the lower rate so you don’t miss out on potential savings.

It depends on the lender. Some carry out a soft search that doesn’t affect your credit score, while others perform a hard check that appears on your file.
We’ll always choose the most suitable route for your circumstances and discuss the implications before proceeding.

Your rate is locked only when we submit your full mortgage application with the chosen lender and product.

It’s best to avoid taking on any new credit or making unnecessary credit applications until your property has completed.
Lenders may run additional checks before releasing funds, and new borrowing can affect your affordability assessment or credit score.
If something is essential and doesn’t increase your monthly commitments, that’s usually fine — but always check with us first to be sure.

When and Why to Get a Property Survey – Beyond the Mortgage Valuation

Know the Real Condition of your future home

Would you spend £500 to avoid a £10,000 mistake?


That’s the kind of risk property surveys are designed to manage. While a mortgage valuation checks if a home is suitable for lending, a survey digs deeper into the property itself — helping buyers make confident, informed decisions.

This article explains the difference between a mortgage valuation and an independent survey, outlines the options available, and explores when it makes most sense to get one. We also look at how surveys can affect real purchase decisions, including two case studies from our clients.

Mortgage Deposit Source & Evidence – What Lenders Expect

Is Your Deposit

When buying a property with a mortgage, it’s easy to focus on rates, monthly payments, or loan sizes—but your deposit source and the evidence behind it can make or break your application. This often-overlooked detail has become increasingly important with tighter anti-money laundering checks and lender scrutiny. In this article, we explain what lenders and solicitors need to see, which sources are acceptable, and how you can avoid delays by getting it right from the start.

Acceptable Sources of Deposit

  • Savings from Regular Earnings

This is the most straightforward and widely accepted source. Whether saved in the UK or in your personal accounts abroad, lenders will assess the plausibility of your savings by reviewing your income, outgoings, dependants, and duration of savings.

For example:

  • A couple earning £80,000 jointly with two dependants and a consistent earning history over six years declaring £150,000 in savings is more credible than a single applicant earning £40,000 over three years with a similar family setup.
  • Funds from investments

Money held in ISAs, investment portfolios, individual company shares, or from company share save schemes can all be used as a deposit source, provided you can show ownership and sale proceeds. Lenders may request valuation reports, sale transaction records, or account statements showing the transfer of funds into your account.

  • Capital raised from a remortgage of another property 

If you already own a property and are raising funds through a remortgage, this is usually acceptable, especially for buy-to-let purchases or onward residential moves. You’ll need to provide the remortgage offer, completion statement, and proof that the funds are available or have been transferred.

  • Gifted Deposit from Family

Gifts from close family—typically parents, grandparents, or siblings—are widely accepted. However, each lender has their own criteria. Gifts from extended family (like uncles, aunts, or cousins) are accepted by some lenders but not all, so lender selection becomes key.

Lenders will check:

  • That the gift is non-refundable
  • That the donor has no legal or beneficial interest in the property
  • That the donor has the funds and is not borrowing them
  • Proceeds from the Sale of a Property

A common source, particularly for home movers. If the sale and purchase are simultaneous, evidence is straightforward. But if the sale occurred earlier, lenders will require full documentation—such as the solicitor’s completion statement and bank statements showing the deposit funds received from the sale.

  • Sale of Other Assets

Funds generated from the sale of cars, jewellery, businesses, or similar are accepted with appropriate evidence. You will need to show:

  • Proof of ownership
  • Sale agreement or receipt
  • Bank trail of money entering your account
  • Repayment of a Previous Loan

If you have previously loaned money to someone and they’re now repaying you, this can be accepted as part of your deposit—provided you have clear documentation showing the original transfer and the repayment. Lenders will typically look to verify key details such as the names involved, the amount originally loaned, and the amount being returned to ensure the funds are genuinely yours. Id documents, proof of funds and a loan repayment letter will be required.

  • Incentives from a New Build Developer

Some property developers offer financial incentives, such as cash contributions towards your deposit. These are generally acceptable, subject to each lender’s specific criteria. However, it’s important to note that most lenders cap the allowable developer contribution at a maximum of 5% of the purchase price. Anything beyond this may be deducted from the purchase price for lending purposes or may not be accepted at all.

Lenders will also assess how the incentive is structured—whether it’s a straightforward cash contribution, a discount on price, or a package (e.g. paying stamp duty or legal fees)—and treat each case accordingly.

Sources That Are Typically Not Accepted

 

While some sources may occasionally be accepted under special circumstances, the following are generally not viewed favourably:

  • Loans Used as Deposit

Lenders typically do not accept borrowed money as a deposit, as this affects affordability and introduces repayment risk. Some exceptions exist (e.g. inter-family loans on specific terms), but these are rare and require full disclosure.

  • Gifts from Friends

Most lenders do not accept gifts from friends, viewing them as potential undisclosed loans rather than true gifts.

  • Unexplained Cash Deposits

Large cash deposits raise red flags for anti-money laundering checks. These are scrutinised heavily, and unless there’s a verifiable paper trail, they are best avoided during your deposit-building phase.

  • Savings or funds originating from cryptocurrency

Due to the difficulty in verifying the origin and movement of funds in crypto wallets, most lenders do not accept deposits that were held or generated through cryptocurrency—even if the money has since been converted into a standard bank account.

  • Lack of Evidence for a Valid Source

Even if the deposit source is normally acceptable, it may be rejected without appropriate documentation to support it. It’s not just the lender who needs to be satisfied—the solicitor handling the purchase is also responsible for verifying the legitimacy of the funds under anti-money laundering regulations. If the evidence is incomplete or unclear, the solicitor may refuse to proceed, even if the lender has initially accepted the deposit in principle.

Understanding Your Deposit

Myth: “If It’s Been in My Account for a Long Time, I Don’t Need to Prove It”

A common misconception is that if funds have been sitting in your bank account for a long time, you don’t need to show the source. This is not true. Regardless of how long the money has been in your account, lenders and solicitors will still ask for evidence of its origin.

Our Recommended Approach: Be Upfront and Honest

At Nachu Finance, we strongly recommend a transparent approach when it comes to your deposit. If the source is genuine—even if slightly unusual—it’s often easier to present it honestly than attempt to frame it as something more ‘standard’.

Our role is to:

  • Understand your deposit source from the start
  • Anticipate the lender's stance
  • Recommend a lender most likely to accept it
  • Support you with all the documentation needed

This may mean a bit more admin early on, but it ensures fewer delays and surprises later.

Why Lenders and Solicitors Require Deposit Evidence

Lenders and solicitors are bound by anti-money laundering (AML) regulations. Often, solicitors request even more detailed documentation than lenders to fulfil their legal obligations. This is standard and should not be a cause for concern.

Use of Technology in Evidence Collection

Some solicitors now use third-party apps and digital tools to collect and verify documents more efficiently. This doesn’t change the need for documentation—it just streamlines the process for both parties.

Estate Agents May Ask Too

Increasingly, estate agents also request evidence of deposit before taking a property off the market. This is to ensure buyers are credible and to meet their own AML compliance obligations.

Best to Avoid Multiple Transfers

We often see cases where clients move money between their own bank accounts multiple times before the funds settle in the final deposit account. While this isn’t necessarily a problem for lenders or solicitors, it does mean more paperwork.

If your deposit has passed through several accounts—for example, from Account A to B, then C, then D, before ending up in Account E—be prepared to provide bank statements for all five accounts. Each transfer must be clearly documented to establish a full trail of funds.

To make things simpler:

  • Try to consolidate funds early in one or two accounts.
  • Avoid unnecessary back-and-forth transfers between accounts.
  • Provide full, unredacted bank statements for any accounts involved in the deposit trail.

This helps reduce delays and makes it easier for everyone involved in the mortgage and legal process to verify your deposit source.

Common Documents Required to Prove Your Deposit

The documents required will depend on the source of the funds, but here’s a general guide based on what lenders and solicitors typically ask for:

  • For Savings (from Income)
  • Bank statements showing where the money is currently held.
  • Supporting statements from any linked or feeder accounts.
  • Savings build-up evidence: While “five years” is often cited, the actual duration depends on how long you’ve been saving. Lenders will want to see a pattern that aligns with your income and expenses. For example, one month’s bank statement per year (e.g. every June) helps illustrate this.
  • For Sale of Property or Other Assets
  • Completion statement from solicitor (for property sale) or sale invoice/receipt (for other assets like a car or jewellery).
  • Bank statement showing proceeds credited to your account.
  • For Gifted Deposits (from Family)
  • Donor’s ID (valid photo ID, ideally passport or driving licence).
  • Proof of donor’s funds (bank statements showing how they built or held the gift amount).
  • Gifted Deposit Letter – confirming it’s a gift, not a loan, with no interest in the property (we can help you draft this).
  • Bank statement showing the gift transfer into your account.
  • Forex conversion documentation if gifted from abroad.
  • For Repayment of a Previous Loan Given by You
  • Proof of the original loan transfer from you to the borrower.
  • A letter from the borrower confirming it is a repayment, not a new gift or loan.
  • Bank statement showing the returned funds entering your account.
  • General Best Practices
  • Provide clear copies of all bank statements (PDFs, not screenshots, with no redactions).
  • Highlight relevant transactions where needed to help the case handler or underwriter.
  • Be proactive—gather all relevant documents early and keep them in one place.

How Nachu Finance Can Help

We can’t make an unacceptable source of deposit magically become acceptable—but we can help you find a lender who will work with your circumstances.

Over the years, we’ve built long-standing relationships with a wide range of mortgage lenders. This allows us to understand which lenders are more likely to accept specific deposit sources that others may decline.

Our client-first approach means we always deal with this important aspect of the mortgage process upfront. By understanding your deposit position early and matching you with the right lender, we help avoid unnecessary delays or disappointments later.

Back in 2013, Rishi, a first-time buyer earning a basic salary of £74,000 plus an annual bonus of over £10,000, was keen to purchase his first home priced at £250,000. While affordability for the mortgage wasn’t an issue, the main challenge was the deposit—he didn’t have enough saved.

To bridge the shortfall, Rishi was willing to take out a personal loan. However, using a loan as a source of deposit is typically not accepted by most mortgage lenders, as it impacts both affordability and risk perception.

At Nachu Finance, we reviewed the case carefully. Given that the overall affordability remained strong even after accounting for the personal loan repayments, we approached one of our trusted high street lenders—known to consider such scenarios on a case-by-case basis. After discussing the application directly with our relationship manager at the bank and presenting the full picture transparently, the mortgage offer was issued without delay.

We also advised the solicitors upfront about the arrangement and confirmed that the lender had approved the use of a personal loan for the deposit. The purchase completed smoothly, without any last-minute hurdles.

Since then, we’ve successfully supported many clients in similar situations—where the source of deposit may not be straightforward, but the case is genuine, and the affordability checks out. With the right guidance and lender selection, even cases that don’t fit the standard mould can be placed confidently.

Our Transparency Promise

At Nachu Finance, our transparency promise means we leave no stone unturned at the outset. This includes a thorough due diligence process—where reviewing your deposit source and ensuring the evidence stands up to scrutiny is a central part.

Yes, we are on your side. But we are also realistic about what lenders and solicitors will require. That’s why we prefer to examine the deposit documentation in detail at the beginning, so we’re ready with the right explanations or supporting documents if queries arise.

So please don’t take it the wrong way if we request detailed paperwork early on—it’s all in your best interest and helps avoid issues further down the line.

Ready to Secure the Right Mortgage for Your Situation?

If there’s a way to place your case, we will find it.

At Nachu Finance, we pride ourselves on understanding each client’s unique situation. If your deposit source is acceptable to even a small number of lenders, we’ll identify them and present your case in the best possible light.

Whether your deposit is coming from multiple sources, overseas accounts, or less common routes, we’ll help you gather the right documentation and guide you every step of the way.
