Most homebuyers go through the mortgage application process once or twice in their lives. Understanding what happens at each stage — in the right sequence, with realistic timelines — prevents the anxiety that comes from not knowing what to expect. This guide explains the complete process from initial conversation to completion keys, with specific context for buyers and remortgagers in Hampshire and Surrey.
Stage 1: Agreement in Principle (AIP)
An agreement in principle (also called a decision in principle or mortgage in principle) is a conditional indication from a lender that they would lend you a specific amount, subject to full application and valuation. For a standard employed buyer it takes 20 minutes and involves a credit check.
Soft vs hard credit search: some lenders run a soft search for the AIP (visible to you, not to other lenders) and a hard search only when the full application is submitted. Others run a hard search at AIP stage. Multiple hard searches in a short period can slightly reduce your credit score. We use soft-search AIP approaches wherever available.
The AIP is not a mortgage offer. It does not guarantee a mortgage will be granted. But it gives you a credible maximum budget for property viewing and signals to estate agents that you are a serious buyer. In the competitive Hampshire and Surrey market, most agents expect AIP evidence before accepting offers.
Stage 2: Making an Offer
With AIP in hand, you make an offer on a property. In England (unlike Scotland), offers are not legally binding until exchange of contracts. Either party can withdraw at any point before exchange. The offer is negotiated verbally or in writing through the estate agent. When accepted, the agent takes the property off the market and marks it SSTC (sold subject to contract).
Stage 3: Full Mortgage Application
Once an offer is accepted, the full mortgage application is submitted. The application requires: proof of identity and address, proof of income (payslips, SA302 for self-employed, accounts for directors), bank statements (typically 3 months), details of the property. The application is submitted to the lender along with the valuation instruction. The lender’s credit underwriters review the full application against their lending criteria.
Timeline: full applications submitted within 2 to 5 days of offer acceptance. Submitted to the right lender first time, based on our pre-application lender confirmation. No re-applications to different lenders, which would generate additional hard credit searches.
Stage 4: Valuation
The lender instructs a valuation on the property. For standard residential purchases, most lenders use automated valuation models (AVMs) that complete immediately. For larger loans, unusual properties or where the AVM produces a significantly different value from the purchase price, a physical valuation by a RICS surveyor is instructed. Physical valuations take 1 to 2 weeks to complete.
The valuation is for the lender’s purposes, not yours. It confirms the property is worth what you are paying. It is not a structural survey. For any property older than 20 years, we recommend a separate homebuyer’s report or full structural survey at your own cost — particularly for the Victorian, Edwardian and 1930s stock common across Hampshire and Surrey.
| Stage | Typical Timeline | Key Documents |
|---|---|---|
| AIP | 20 minutes | ID, income summary, credit check |
| Offer accepted | Immediate | N/A — verbal or written |
| Full application submitted | 2–5 days after offer | Payslips/accounts, bank statements, ID |
| Valuation completed | 1–10 days (AVM) / 1–2 weeks (physical) | Property address, purchase price |
| Formal mortgage offer issued | 2–4 weeks after application | None — reviewed and signed |
| Exchange of contracts | Week 8–12 typically | Signed contracts, deposit transfer |
| Completion | 1–4 weeks after exchange | Remaining funds transfer |
Stage 5: Formal Mortgage Offer
Once the application is approved and the valuation confirms the property value, the lender issues a formal mortgage offer. This is a legally binding offer that remains valid for a specified period — typically 6 months for standard residential, extended to 12 months for new build purchases. You and your solicitor review the offer. Your solicitor checks the terms and confirms there are no unusual conditions. The offer is accepted and the legal process progresses to exchange.
Stage 6: Legal Process and Exchange
Your solicitor (conveyancer) manages the legal process in parallel with the mortgage application. The key stages: instruction and ID verification; property searches (local authority, drainage, environmental); review of title documents from the seller’s solicitor; raising and resolving enquiries about the property; mortgage deed review; pre-exchange checks and signing; exchange of contracts with simultaneous deposit payment. The deposit (typically 5% to 10% of the purchase price) transfers to your solicitor in readiness for exchange. At exchange, the completion date is set and both parties are legally bound.
Stage 7: Completion
On completion day, the mortgage funds transfer from the lender to your solicitor and then to the seller’s solicitor. The purchase completes, you receive the keys and the property is legally yours. SDLT is paid by your solicitor within 14 days of completion. The Land Registry registers the transfer of ownership, which takes several weeks after completion but has no practical effect on your occupation of the property from completion day.

The most common reasons mortgage applications are delayed or declined: incomplete income documentation submitted (the application has to be restarted); declined application from the wrong lender (hard search registered, application starts again); property down-valued below purchase price (renegotiation or additional deposit required); adverse credit discovered at application (pre-application credit check would have identified this); chain collapse (sale falls through above or below). Our process addresses each of these before application: income documentation confirmed complete before submission; lender confirmed suitable for both income and property before application; property acceptability confirmed with the lender; credit file reviewed at soft search stage; chain position assessed before application commitment.
The New Build Timeline
New build purchases require offer extension management that standard resale does not. If the build completes later than the mortgage offer’s validity period, the offer expires and a new application is required. We use new build specialist lenders who issue 6 to 12-month offers and commit to extension policy before any application is submitted. The extension request must be submitted before the offer expires, not after. For Manydown Garden Town, Farnborough regeneration and other active Hampshire and Surrey new build sites, we track the build timeline and submit extension requests proactively without waiting for the client to remind us.
