A 90-day mortgage preparation framework

In short

Ninety days is our own organisational framework for working through your own information calmly. It is not a lender timetable, not a legal timetable, not an application-processing estimate and not a prediction of completion. You do not have to wait 90 days, and working through it does not change what any lender decides. If your purchase or remortgage is already under way, use whichever phase matches where you actually are.

Who this is for

  • Anyone who wants a structure for organising their own information before a mortgage conversation
  • People who prefer a phased plan to an open-ended to-do list
  • Anyone part-way through the process who wants to check what they have and have not gathered

Key points

The 90 days are ours, not anyone else's

Our suggestion, nothing more. No lender, regulator or conveyancer works to this framework, and no source is cited for it because none exists. It is a way of ordering your own work, and you can compress it, stretch it or reorder it.

Roughly 90 to 61 days — understand and organise

Our suggestion: work out what your own picture actually is. Who you are and how you evidence it, how your income is structured, what regular commitments you have, where any deposit or other funds have come from, whether the information about you held by credit reference agencies is accurate, and a written list of the things you are unsure about.

Roughly 60 to 31 days — clarify

Our suggestion: stop guessing and ask. Ask the actual lender or FCA-authorised firm what evidence applies to your circumstances. Where you find factual errors in information held about you, take them up through the proper route. Do not manufacture documents, and do not alter ordinary financial behaviour purely to try to look a certain way — we do not suggest that and it is not something we can predict the effect of.

Roughly 30 to 1 days — assemble

Our suggestion: gather the current evidence that has actually been asked for, note anything about your circumstances that has materially changed, prepare your questions, and make sure you understand the costs and the process that will apply to you.

Application and transaction stage — follow the real process

Once an application and a transaction are under way, the process that matters is the lender's own process and the conveyancing process for your transaction and your jurisdiction. Follow those, and ask your lender, your FCA-authorised firm and your solicitor or conveyancer what happens next in your case.

Your transaction may not look like this at all

It may be shorter, longer, reordered, delayed, or already under way while you use this framework. That is normal, and it is not a sign that anything has gone wrong.

Exceptions and things that vary

  • Corrections to information held about you are outside your control once raised, so start those first if they apply to you.
  • Self-employed people may need to work around their own filing and record dates.
  • If a product period is ending, your own window may be much shorter — that is about your circumstances, not about this framework.
  • In England and Wales, GOV.UK says buying a home takes about five months on average and can take longer in a chain. That is the source's average for a whole transaction, not a target, not a timetable and not a prediction for your purchase.

How to work through it

  1. Decide your own starting point

    Our suggestion: pick the phase that matches where you actually are rather than starting at 90 days by default.

  2. Write down what you already hold

    Our suggestion: one list of what you have, one list of what you cannot locate, and a note of who you would have to ask for each missing item.

  3. Ask before you assemble

    Our suggestion: confirm with the lender or firm what is actually needed in your case before spending time collecting things nobody asked for.

  4. Keep it current

    Our suggestion: re-check your own pack before a meeting so names, addresses and dates are consistent. We do not state how old any document may be — that is for the lender to specify.

  5. Hand over to the real process

    Our suggestion: once an application is submitted, treat the lender's process and your solicitor's or conveyancer's process as the authority on what happens when.

Illustrative example (not a real case)

Imagine someone using this framework who is not buying yet. In the first phase they find that information held about them lists an old address; they raise it and wait. In the second phase they ask a firm what evidence would apply to their income. In the third they gather only what was asked for. Then a property comes up sooner than expected and they move straight to the real process. The framework was a way of ordering their own work, not a schedule anything else had to follow. Illustrative only.

Illustrative only. Figures and situations in examples are made up to show a method. They are not typical, not a benchmark and not a prediction of any outcome.

What not to assume

  • Do not assume 90 days is how long an application, a valuation, conveyancing or a chain takes.
  • Do not assume you must wait 90 days, or any period, before speaking to anyone.
  • Do not assume that working through this framework speeds up, improves or influences any lender decision. It does not, and we make no such claim.
  • Do not assume 'at day X you must do Y'. Nothing here is a lender rule or a legal rule.
  • Do not assume England and Wales terminology applies across the UK. Exchange of contracts and completion are England and Wales terms; in Scotland the equivalent milestones are conclusion of missives and settlement on the agreed date of entry, and Northern Ireland has its own process.
  • Do not assume this framework replaces advice from an FCA-authorised mortgage firm or from your own solicitor or conveyancer.

Questions for a qualified adviser

We cannot answer these for you, and we do not introduce or recommend advisers. Take them to a suitably qualified FCA-authorised mortgage adviser of your own choosing.

  • Given my circumstances, what evidence would you actually need from me?
  • Is anything in my own information likely to need clarifying before we go further?
  • What should I have ready before our next conversation?
  • Which parts of the process from here are yours, which are the lender's, and which are my solicitor's or conveyancer's?
  • What in my situation is worth resolving before an application rather than during one?
