Buying a home involves a long chain of steps, most of which happen out of sight. If you have never done it before — or it has been a decade since you last did — the process can feel like a black box. Here is the whole journey, in order, with a rough sense of timing at each stage.

Step 1: Budgeting and affordability

Before you look at a single property, work out what you can genuinely afford. Lenders will typically lend around 4 to 4.5 times your annual income, sometimes more, but the real question is what monthly payment fits your life once bills, childcare, travel and everything else are accounted for.

You will also need a deposit — usually at least 5% of the purchase price, though 10% or more opens up better rates. Do not forget the extras: legal fees, survey costs, possible stamp duty, and moving costs. A few thousand pounds set aside beyond the deposit saves a lot of stress later.

Step 2: Decision in principle

A decision in principle (also called an agreement in principle) is a lender’s initial indication of how much they would be willing to lend you, based on a soft look at your income and credit profile. It usually takes minutes to a day to obtain and lasts 60 to 90 days.

It is not a guarantee — but estate agents increasingly expect to see one before taking your offer seriously, so it is worth getting early.

Step 3: Property search and making an offer

This is the part everyone pictures: viewings, second viewings, and eventually an offer through the estate agent. Offers in England and Wales are not legally binding at this stage — either side can still walk away — so treat an accepted offer as the starting gun, not the finish line. (Scotland works differently, with offers becoming binding earlier through the missives process.)

Step 4: Full mortgage application

Once your offer is accepted, the full application goes in. This is where the paperwork lives:

  • Payslips (usually three months) or two to three years of accounts if self-employed
  • Bank statements
  • Proof of deposit and ID
  • Details of debts and outgoings

Accuracy matters. Small inconsistencies between what you declared and what your documents show are the most common cause of delays.

Step 5: Valuation vs survey — they are not the same thing

The lender will arrange a valuation. This is for their benefit, not yours — it simply confirms the property is worth roughly what you are paying, so their loan is secure. It may be a quick visit or even a desktop exercise.

A survey is for you. A HomeBuyer Report or full building survey digs into the condition of the property — damp, roof, structure, wiring. It costs extra, and it is optional, but on older properties especially it can save you from expensive surprises.

Step 6: Underwriting

Behind the scenes, the lender’s underwriters check everything: your income, credit history, the valuation, the source of your deposit. This typically takes anywhere from a few days to a few weeks. They may come back with questions — that is normal, not a bad sign. Respond quickly and the process keeps moving.

Step 7: The mortgage offer

If underwriting is satisfied, the lender issues a formal mortgage offer, usually valid for three to six months. This is the document that says: yes, we will lend you this amount, on these terms. It goes to you and your solicitor.

Step 8: Conveyancing, exchange and completion

Your solicitor or conveyancer handles the legal side: searches (checking for planning issues, flood risk, disputes), reviewing contracts, and raising enquiries with the seller’s solicitor. This is often the slowest stretch — six to twelve weeks is common.

Two dates matter at the end:

  • Exchange of contracts — the point of no return. You pay your deposit, and both sides are legally committed. Pulling out after exchange means losing your deposit.
  • Completion — the mortgage funds move, the keys are handed over, and the property is yours. Often a week or two after exchange, sometimes the same day.

What happens after: rate expiry and remortgaging

Most people take a fixed rate for two, three or five years. When that fixed period ends, you roll onto the lender’s standard variable rate — which is almost always higher. Diarise a reminder for six months before your deal ends: that is when you can start reviewing options, either with your current lender (a product transfer) or a new one (a remortgage). Doing nothing is usually the most expensive choice.

The expat angle: buying abroad works differently

If you are moving country — say, a UK-to-Cyprus move — do not assume the process travels with you. In Cyprus, for example, there is no broker market to speak of: you generally go direct to individual banks and compare their terms yourself. Deposits tend to be higher (often 30% or more for non-residents), the paperwork is different, and independent legal advice is essential rather than optional, particularly around title deeds. Timelines can also be less predictable than the UK’s. The principles — affordability, documentation, legal checks — are the same everywhere; the mechanics are not.

The whole journey at a glance

From first budgeting session to keys in hand, three to six months is typical. The parts you control — paperwork, responsiveness, choosing your team early — are the parts that most often decide whether you land at the faster end of that range.
