Mortgage timeline: how long each stage takes, from application to completion

Once your full application is in, most lenders issue a mortgage offer within two to four weeks. Buying the home itself takes longer: from offer accepted to completion usually runs three to five months in England and Wales, and Rightmove's latest figures put the average at 154 days. Here's what happens at each stage, how long it typically takes, and what you can do to keep things moving.

Mortgage timeline at a glance

These are typical ranges for a purchase in England and Wales, not promises. A chain-free buyer with paperwork ready can move faster. A long chain, a leasehold flat or a slow council search can add weeks.

Rightmove's July 2026 data shows an average of 154 days from sale agreed to completion across Great Britain (153 days in the West Midlands, 174 in London). That average includes chains, so a simple purchase is often quicker.

The stages, one by one

1. Agreement in principle

An agreement in principle (AIP, also called a decision or mortgage in principle) is a lender's initial indication of how much it might lend, based on your income, outgoings and a credit check. It usually takes minutes online or a day or two through a broker. Estate agents often ask for one before they put your offer forward. It isn't a guarantee of a mortgage.

2. Offer accepted on a property

The clock really starts here. Instruct a solicitor or licensed conveyancer straight away, and let your broker know so the full application can go in. Every day between these two steps is a day added to the end.

3. Full mortgage application

This is where you give the lender everything: payslips or accounts, bank statements, ID, proof of deposit and details of the property. If your documents are ready, the application can be submitted within a day or two. Missing or unclear paperwork is the most common reason a case stalls at this point.

4. Valuation

The lender instructs a valuation to check the property is suitable security for the loan. Some are done from desktop data within a day or so. Others need a surveyor to visit, which can take one to two weeks to book in busy periods. A valuation is for the lender, not you, so consider paying for your own survey too. If the figure comes back below the price, read our guide on what to do when a property is down-valued.

5. Underwriting

An underwriter checks your income, spending, credit history and the valuation against the lender's criteria. Straightforward employed cases can clear in a few days. Self-employed income, bonuses, recent job changes or credit issues can mean extra questions and a longer wait. We explain what they look for in mortgage underwriters: behind the scenes of your application.

6. Mortgage offer

When the underwriter is happy, the lender issues a formal mortgage offer to you, your broker and your solicitor. MoneyHelper puts the usual wait at two to four weeks from application, sometimes up to six.

7–9. Conveyancing, exchange and completion

The legal work runs alongside the mortgage from the day you instruct your solicitor, and it's usually what takes longest. We cover it in detail below.

How long does a mortgage application take?

For most buyers, two to four weeks from submitting a full application to receiving the offer. Simple cases with an automated valuation can be quicker, sometimes under a week. Complex income, a property that needs a physical inspection, or a lender with a backlog can push it past a month. Having your documents ready before you apply is the single biggest thing you can control.

What happens after a mortgage offer?

A mortgage offer means the lender has approved your loan, but you don't own anything yet. The legal side has to catch up before you can exchange.

1. Solicitor reviews the offerThey check its conditions and confirm the property meets the lender's requirements.
2. Searches and enquiriesLocal authority, water and drainage searches come back, and questions to the seller's solicitor are answered.
3. ExchangeYou sign the contract, pay the deposit and become legally committed to buy.
4. CompletionThe lender releases the money, the seller gets paid and you get the keys.

While you wait, avoid anything that changes the picture the lender approved: new credit, a change of job or large unexplained transactions. Lenders can re-check your circumstances and credit file before releasing funds, and they can withdraw an offer if something material has changed.

How long from mortgage offer to exchange?

It depends on how far the legal work has got. If searches are back and enquiries are answered when the offer arrives, exchange can follow within one to three weeks. If the conveyancing is still in its early stages, four to eight weeks is more realistic, and longer in a chain because everyone has to be ready on the same day.

Local authority searches are a frequent bottleneck. Many councils return them within about two weeks, but some take considerably longer. Leasehold flats also need information from the freeholder or managing agent, which is one reason Rightmove finds flats take around 20 days longer to complete than houses.

How long from exchange to completion?

Usually one to four weeks, and completion can happen on the same day as exchange if everyone agrees. The date is fixed in the contract at exchange. Your solicitor then requests the mortgage funds from your lender, which normally needs several working days' notice.

Two things to sort at exchange: you'll pay a deposit, commonly between 5% and 10% of the price, and you'll need buildings insurance in place because you become responsible for the property from that point. Pulling out after exchange can cost you the deposit.

On completion day the money usually moves in the morning and keys are often released around lunchtime. Your solicitor then files the Stamp Duty Land Tax return (Land Transaction Tax in Wales) and registers you as the owner with HM Land Registry.

How long does a mortgage offer last?

Most mortgage offers on existing homes are valid for six months from the date they're issued, although a few lenders set shorter periods. New-build purchases can have longer validity, and some lenders offer products lasting nine or even twelve months because build dates slip.

With average transactions now close to five months, running out of time is a real risk. Some lenders will extend an offer, but they may ask for updated payslips, a fresh credit check or a new valuation, and the rate may not be held. If completion is drifting, raise it early.

What causes delays, and how to avoid them

• Missing documents. Gather payslips, three months of bank statements, ID and proof of deposit before you apply.
• Slow legal instruction. Choose your solicitor while you're still house-hunting, and return their forms and ID checks promptly.
• Down-valuations and survey problems. These can force a renegotiation or a change of lender. Book your own survey early.
• Searches and leasehold information. Your solicitor can't speed up the council, but they can order searches the moment you instruct them.
• Chains. One slow link holds up everyone. Ask the agent how long the chain is before you commit to dates.
• Silence. Cases stall when nobody is following up. At Quick Mortgages we chase lenders and keep in touch with solicitors and agents, so problems surface early.

How long does a remortgage take?

Much less time, because there's no seller or chain. A product transfer with your current lender can often be arranged within days. Moving to a new lender typically takes four to eight weeks, including a valuation and legal work, which many lenders provide free.

Many lenders let you secure a new deal around six months before your current one ends. With Bank Rate held at 3.75% on 17 September 2026 and markets expecting rises, starting early gives you a rate to fall back on. See our remortgage service for how we help.

Is the process different in Scotland?

Yes. In Scotland the seller provides a Home Report upfront and the deal becomes binding when missives are concluded, rather than at exchange of contracts. Rightmove's figures show Scotland is the fastest part of Great Britain, averaging 98 days from sale agreed to completion. This guide focuses on England and Wales.

Frequently asked questions

Is an agreement in principle the same as mortgage approval?

No. An AIP is an early indication based on limited checks. Approval only comes with the formal mortgage offer, after the valuation and underwriting.

Can I get a mortgage offer in a week?

Sometimes. A straightforward employed case with complete paperwork and an automated valuation can be offered within days. Plan for two to four weeks, though.

Do I need a mortgage offer before exchanging contracts?

Yes. Once you exchange you're legally bound to buy, so your solicitor will not let you exchange until the offer is in place and its conditions are met.

Can a lender withdraw a mortgage offer?

Yes, before completion, if your circumstances change, information turns out to be wrong, or there's a problem with the property. Keep your finances steady until you have the keys.

How long does the whole process take for a first-time buyer?

Without a chain, often around two to four months from offer accepted to completion. You can speed it up by having an AIP, your documents and a solicitor lined up before you find a home.
