Day one remortgage criteria: a broker’s guide

A day one remortgage, a buy-to-let remortgage placed inside six months of purchase to release capital or repay short-term finance, is placed by answering two questions before anything else: which lenders will consider the case at all, and which valuation basis they will apply.

Those two answers set the loan, and they vary more between lenders than almost anything else in buy-to-let. This guide covers the placement of a day 1 remortgage case: how lenders measure the ownership period, which valuation basis applies, what an underwriter will want to see, and how to time the case so a bridge is repaid before its term runs out. For what these cases are and why landlords use them, read our post on day 1 remortgages.

Which lenders consider a day one remortgage?

Fewer than will consider a standard remortgage, and the split is along predictable lines.

Mainstream and high street lenders commonly apply a minimum ownership period as internal credit policy, usually six months and sometimes twelve. Several state it explicitly in their Part 2 entry in the UK Finance Mortgage Lenders’ Handbook, where a lender will say that on a remortgage application the customer must have owned the property for at least six months, often with an exception where the property was inherited. Where that policy exists, it is a flat bar rather than a judgement, so no amount of case preparation moves it.

Lenders that underwrite individually rather than by automated score are more likely to consider the case on its facts, because the risk the six-month rule manages, an unexplained rise in value shortly after purchase, is one an underwriter can look at directly. Buy-to-let lenders are more likely to sit in this group than residential ones.

Within that smaller field there is a second split, covered below: some will lend inside six months but only against the purchase price, and others will use the current valuation. A lender saying yes to the ownership question has not yet answered the valuation question, and the second one usually decides whether the case is worth placing there.

The practical route is criteria sourcing to build the list, then a conversation to confirm the valuation basis before you submit. On a day one case, assumption is expensive.

Why the six-month rule narrows the field on a day one remortgage

The six-month rule is lender policy, not legislation or regulation. Its roots are in clause 5.1.1 of the UK Finance Mortgage Lenders’ Handbook, which asks the conveyancer acting for the lender to report immediately where the owner or registered proprietor has been registered for less than six months. That is a reporting duty. It flags short ownership so the lender can decide what to do, rather than prohibiting the loan.

What each lender does with that flag is set out separately, in its own Part 2 answers, which is where the actual restriction lives. That is why two lenders reading the same clause reach different answers, and why a case declined by one can be placed with another.

The caution behind it comes from back-to-back transactions and inflated valuations in the years before the financial crisis, where a property could be bought and quickly refinanced at a higher figure, leaving the lender carrying most of the risk. Many lenders responded with a minimum ownership period. Others manage the same risk through closer underwriting instead of a time bar.

For placement, the consequence is that a day one remortgage is a criteria question rather than a legal one. It differs lender by lender, it can change, and it is worth confirming current criteria rather than relying on where a case placed last year.

How lenders measure the ownership period on a day one remortgage

Two lenders can both say “six months” and mean different things, so this is the first thing to establish on any day one remortgage.

From completion or from registration

Many lenders measure ownership from the date the borrower became the registered proprietor, not the date the purchase completed. That distinction matters more than it sounds, because registration is not quick. HM Land Registry’s published processing times, updated on 22 September 2026, show that of around 440,000 register updates a month, 32.2% take three months or longer, with most of those completing in about six months. First registrations are slower again, with half taking around eight months.

So a landlord who has held the keys for four months may show a much shorter period on the register, or no entry yet at all. Where the client is counting from completion and the lender is counting from registration, the difference can be the whole application.

Whether registration has to be complete by then

Separately from how the period is measured, most lenders want the borrower shown as the registered owner by the time the remortgage completes. If the transfer is still pending, that sets the earliest possible completion date regardless of how quickly everything else moves.

What the title shows

Unregistered titles, a pending first registration, or a title still showing the previous owner all complicate the same question, and the processing times above explain why. Pull the title up at the start of the case, establish the registration date, and place against it. On a Scottish property the same applies at the Registers of Scotland. Where several complications stack at once, the approach in our guide to complex buy-to-let cases applies here too.

Which valuation basis applies to a day one remortgage

This decides how much capital a day one remortgage can release, and lenders split two ways.

Criteria	How lenders differ	What to check
Time owned	Some lenders need 6 months of ownership. Others will lend from the day of purchase.	The minimum ownership period, and whether it runs from completion or registration
Valuation basis	Some use the lower of the purchase price and current value. Others use current market value.	Which value the LTV is worked out on
Uplift in value	Where the value has gone up soon after purchase, some lenders cap the LTV or ask for evidence of the works.	Any LTV cap on an uplift, and what evidence is needed
Capital raising	Some lenders allow it for most purposes. Others limit it or don’t allow it.	Which purposes are accepted
Refinancing exits	Not every lender will refinance bridging or development finance.	Whether bridging and development exits are accepted
Borrowers	Lenders differ on limited companies, LLPs and first-time landlords.	Whether your client’s borrower type is accepted
Underwriting	Some lenders use automated scoring. Others underwrite each case individually.	Whether a complex case will get a person reviewing it

The difference is usually the reason a case places with one lender rather than another.

Take a property bought at £180,000 with £25,000 of works, now valued at £240,000. On a 75% loan-to-value, the first basis produces £135,000 and the second £180,000. That is £45,000 of capital, and the client’s plan almost certainly assumes the second figure. Even on the higher one, £25,000 of the landlord’s own money stays in the property, which is the position lenders are looking for.

Two further points shape which basis a lender will apply to a day one remortgage. Where value has risen with no works at all, expect questions, because a property bought below market value may well be worth more than was paid, but the lender will want to understand the circumstances and confirm the transaction was at arm’s length. And where the property has been improved, the case will usually need a physical valuation, since automated valuations rely on existing value evidence and, as our guide to AVMs in buy-to-let explains, they are not suited to recently improved or converted property.

What the underwriter will want to see on a day one remortgage

A day one case is underwritten on the story behind the purchase as much as the numbers. Assembling this at submission rather than in response to questions is the single biggest thing a broker can do for the timeline.

• The purchase. Price, completion date, and whether it was bought at auction, by private treaty, or between connected parties.
• Source of funds. Evidence of where the money for a cash purchase came from, or a redemption statement for the bridging or development finance being repaid.
• The works. A schedule with costs, invoices, and before and after photographs where value has increased.
• An explanation of the uplift. A short factual note on why the property is worth more than was paid.
• Condition. The property needs to be habitable and lettable when the valuer attends, not partway through works.
• The rent. The rental stress test still sets the maximum loan, and on a capital raise it often bites before loan-to-value does, so check it against a realistic rental figure early.
• The purpose of the capital. Most lenders accept capital raising for property investment and exclude some purposes, so confirm the client’s intention is within criteria before submitting.
• The structure. Where the property is being remortgaged by a company that has just acquired it, the structural questions on any company case apply on top.

Inherited and gifted property

Inherited property is the most common exception to the six-month rule, and the one case where a day one remortgage is often available from lenders that otherwise decline them. A beneficiary becomes the registered owner without buying the property, so there is no purchase price to compare a valuation against and none of the back-to-back risk the rule exists to manage. Several lenders that otherwise require six months of ownership on a remortgage carve inherited property out explicitly in their Part 2 entry, usually where the conveyancer confirms in writing that the property was inherited following the death of the previous owner.

Two things to establish early. Probate needs to have completed and the title transferred into the beneficiary’s name, which brings the registration timings above back into play. And where a property has been transferred between family members rather than inherited, it is a gift or a sale at undervalue rather than an inheritance, which is a different criteria question and does not usually attract the same exception.

Timing a bridge exit on a day one remortgage

Most day one cases are repaying short-term finance, and the common failure is not criteria but the calendar. A bridge taken on the assumption of a quick refinance can run close to its term when works overrun, registration is slow, or the valuation disappoints.

Work backwards from the bridge expiry and allow for each stage: the works finishing, the property being ready to let, registration completing if it has not already, a physical valuation being instructed and reported, and the legal work on the remortgage. Registration is the stage most often underestimated, and on the Land Registry figures above it is the one least within anyone’s control.

Identify the lender at the point the bridge is taken out rather than at the point it is due, so the client’s plan is built around criteria that actually exist. Where the timetable is tight, a lender you can talk a case through with before submission is worth more than a marginally better rate.

Where Landbay fits

We consider buy-to-let remortgage applications where the applicant has been the registered proprietor for less than six months, and day one remortgages are one of our criteria highlights. The property must be registered as owned by the applicant at the date of completion.

Where there is an uplift in value within six months of ownership, loan-to-value may be restricted to 75%. Capital raising is acceptable, excluding tax and gambling, and we accept bridge and development exits. Our full position is set out in our buy-to-let lending criteria, and restrictions apply depending on the case

We lend across England, Wales and Scotland, to individuals and to limited companies and LLPs, and we underwrite individually rather than by automated score, which is what matters on cases where the circumstances of the purchase carry as much weight as the figures.

Checklist before you submit

• How does the lender measure the ownership period, from completion or from registration?
• What does the title show, and will the borrower be the registered owner by completion?
• Which valuation basis will the lender apply, and is there a lower loan-to-value cap where value has increased?
• Do you have the purchase price, completion date and source of funds?
• Where value has risen, do you have the schedule of works, costs and evidence?
• Will the property be habitable and lettable when the valuer attends?
• Does the loan pass the rental stress test at a realistic rental figure?
• Is the purpose of the capital raise within the lender’s criteria?
• If the property was inherited, has probate completed and the title transferred?
• If a bridge is being repaid, does the timetable leave room before it expires?

Frequently asked questions

Which lenders allow a remortgage within six months of purchase?
A smaller group than will consider a standard remortgage. Mainstream and high street lenders commonly apply a minimum ownership period of six or twelve months as credit policy, and several state it in their Part 2 entry in the UK Finance handbook. Lenders that underwrite individually are more likely to consider the case on its facts. Build the list through criteria sourcing, then confirm the valuation basis before submitting.

Is the six-month rule a law?
No. It is lender policy. Clause 5.1.1 of the UK Finance Mortgage Lenders’ Handbook asks the lender’s conveyancer to report where the owner has been registered for less than six months, but it does not prohibit the loan. Each lender sets its own position in its Part 2 answers, which is why the answer varies between lenders and can change.

Do lenders measure ownership from completion or from registration?
Many measure from the date the borrower became the registered proprietor rather than the date of completion. Because registration takes time, around a third of register updates take three months or longer, the two dates can be months apart. Establish which applies before placing the case.

Does the borrower need to be registered as the owner before the remortgage completes?
With most lenders, yes. At Landbay the property must be registered as owned by the applicant at the date of completion, so a pending transfer sets the earliest possible completion date.

Will the lender lend against the purchase price or the new valuation?
Some use the lower of purchase price and current valuation within six months of ownership, so any uplift is disregarded. Others use the current valuation where the increase is explained by works, and may apply a lower maximum loan-to-value. It varies by lender, so establish which basis applies before placing the case.

What evidence does an underwriter need on a remortgage inside six months?
The purchase price and completion date, evidence of the source of the purchase funds or a redemption statement for the finance being repaid, a schedule of works with costs and evidence where value has increased, and confirmation that the property is habitable and lettable.

Can you remortgage an inherited property within six months?
Often yes, and inherited property is the most common exception to the six-month rule. There is no purchase price to compare against and none of the back-to-back risk the rule manages, so several lenders that otherwise require six months carve it out where the conveyancer confirms the property was inherited. Probate needs to have completed and the title transferred first.

Can a Day 1 remortgage be used to repay a bridging loan?
Yes, and it is the most common reason for one. The risk is timing rather than criteria, so work backwards from the bridge expiry, allowing for works, registration, a physical valuation and the legal work.

Can an automated valuation be used on a day one remortgage?
Usually not where the property has been improved. Automated valuations rely on existing value evidence, so a recently refurbished or converted property will generally need a physical valuation to support the new figure.

Does Landbay consider remortgages within six months of purchase?
Yes. We consider applications where the applicant has been the registered proprietor for less than six months, provided they are registered as the owner at the date of completion. Where value has increased within six months of ownership, loan-to-value may be restricted to 75%.

Place the ownership and valuation questions first

A day one remortgage is a criteria case, not an unusual product. Establish how the lender measures ownership and which valuation basis it will apply, assemble the evidence behind the purchase before you submit, and build the timetable backwards from the bridge expiry. Get those three right and the case runs like any other remortgage.

Buy to let is all we do. If you want to talk through a case where the client has owned the property for less than six months, speak to your local BDM.
