How long does a mortgage application really take?

On average, the whole mortgage process – from initial enquiry to getting your keys – takes between 6 to 12 weeks. But that can vary based on how complex your situation is, how fast documents are provided, and how quick your lender is.

Here’s a stage-by-stage breakdown of what happens, how long each bit might take, and what you need to do to keep things moving.

What should you do before applying?

Timeline: 1–2 weeks (or more if you’re still house-hunting)

This prep stage is where you get your financial ducks in a row. Start by checking your credit report (Experian, Equifax, or TransUnion in the UK), reducing unnecessary debt, and saving for your deposit.

Top tip: Get a Mortgage in Principle (MIP) – sometimes called a Decision in Principle (DIP). It gives you an idea of how much you might borrow and shows estate agents and sellers you’re serious.

When do you speak to a mortgage broker?

Timeline: 1–2 days for initial chat

Chatting to a mortgage broker – like us at Quick Mortgages – can save you heaps of time and hassle. We’ll look at your financial situation and recommend the best lenders and deals (and we’re fee-free, too!).

We’ll also help you gather the right paperwork to speed things up.

What you’ll typically need:

  • Proof of income (payslips or accounts if self-employed)

  • Bank statements

  • ID and address verification

  • Proof of deposit

What happens once you submit your mortgage application?

Timeline: 2–4 weeks

This is when your formal mortgage application goes in. The lender will assess your income, outgoings, credit history, and the property you want to buy.

Here’s what’s happening behind the scenes:

  • Underwriting: This is the lender’s deep-dive into your finances.

  • Valuation: They’ll arrange a valuation to make sure the property is worth what you’re paying.

  • Additional checks: They may ask for more documents or clarification.

If all goes well, you’ll get a mortgage offer – essentially a “yes” from the lender.

When do you instruct a solicitor?

Timeline: Immediately after your offer is accepted

Your solicitor (or conveyancer) handles all the legal stuff. They’ll:

  • Carry out property searches

  • Liaise with the seller’s solicitor

  • Handle contracts and deposit transfers

  • Manage the exchange and completion

Top tip: You can compare solicitors and get things moving even before your mortgage offer comes in.

How long between mortgage offer and exchange?

Timeline: 2–4 weeks

Once your mortgage offer is in hand, your solicitor finishes the legal legwork. Once both sides are ready, you’ll exchange contracts – at this point, you’re legally committed.

You’ll also agree a completion date (the day you get the keys).

What happens on completion day?

Timeline: Usually 1–2 weeks after exchange

Your solicitor sends the funds to the seller’s solicitor, the sale is finalised, and you get the keys. Time to pop the champagne (or start unpacking boxes!).

What could delay the mortgage process?

Even the smoothest applications can hit bumps. Here are common delays:

  • Missing paperwork or slow responses

  • Issues in the property chain

  • Down-valuations (if the lender thinks the property isn’t worth the price)

  • Legal complications or slow searches

Best advice: Stay responsive, be organised, and use a broker who can chase things up on your behalf.

How can you speed things up?

Here’s what helps:

  • Have your documents ready from the get-go

  • Get a Mortgage in Principle early

  • Use a proactive solicitor and broker

  • Stay in regular contact and respond quickly to any requests
