Eligibility guide
First-time buyer mortgage requirements: what counts?
There is no single UK test for a ‘first-time buyer mortgage’. A lender decides whether you meet its mortgage and product criteria. Separate rules decide whether you qualify for property tax relief, can use a Lifetime ISA or can enter a homeownership scheme. You may be able to get a mortgage even if you do not qualify for every first-time buyer benefit.
Start with two questions: Have you ever owned all or part of a home, including one abroad or inherited? And where are you buying? Tell your mortgage adviser and conveyancer about any previous ownership before relying on a first-time buyer product, tax relief or savings bonus.
Which first-time buyer test matters?
The answer depends on the rule you are checking. A lender’s label does not settle your tax or savings position.
| Decision | What to check | Who confirms it |
|---|---|---|
| Mortgage and product | Affordability, deposit, credit history, property and the lender’s own product definition. | The lender, with help from your mortgage adviser. |
| Property transaction tax relief | Rules where the property is located and the ownership history of everyone buying. | Your conveyancer or tax adviser. |
| Lifetime ISA withdrawal | The saver’s eligibility and the purchase conditions. | Your ISA provider and conveyancer. |
| Homeownership scheme | Its current location, property and household criteria. | The scheme provider, with mortgage and legal advice where needed. |
Does previous ownership change your position?
It can. For first-time buyer Stamp Duty Land Tax relief in England and Northern Ireland, HMRC looks at whether you have previously acquired a qualifying interest in a dwelling anywhere in the world. A gift or inheritance can count. If you buy jointly, every purchaser must meet the conditions for that relief. Scotland has its own first-time buyer Land and Buildings Transaction Tax relief and rules. Wales has Land Transaction Tax but no first-time buyer relief.
These tax rules are not a universal mortgage rule. If you previously owned a home, sold it years ago, inherited a share, owned abroad or were added to somebody else’s mortgage, explain exactly what happened. A lender may still consider your application, but product eligibility depends on its current criteria. Your conveyancer should confirm the legal and tax effect of any ownership interest. Read our focused guide to buying again after owning a home, or see our UK first-time buyer property tax guide for the four nations in more detail.
What if you are buying with someone who has owned before?
You can still explore a joint mortgage. The lender will assess the applicants and property. Tax relief is a different question: HMRC requires all purchasers to qualify for its first-time buyer SDLT relief, and Scotland also applies an all-buyers test. Under current HMRC rules, a qualifying Lifetime ISA saver can buy with someone who is not a first-time buyer, provided the saver and purchase meet the ISA conditions. Check each point before you commit to buying together.

What will a mortgage lender check?
Being a first-time buyer does not itself mean a mortgage will be offered. A lender considers the whole application, including:
- Income and commitments: accepted income, regular spending and existing borrowing, to assess affordability.
- Deposit and its source: how much you can put in, whether it is saved or gifted, and the evidence needed. Low-deposit products exist, but availability and criteria vary.
- Credit history: information in your credit file, not one universal score that guarantees acceptance.
- Your circumstances: employment or self-employment evidence, residency, mortgage term and any joint applicant.
- The property: value, condition, construction and whether it meets the lender’s security requirements.
If you are self-employed, have credit problems or rely on a gift, explain that early. For detail, use our existing guides to mortgage affordability, 5% deposit mortgages, gifted deposits and self-employed mortgages.
What should you prepare before asking for advice?
- Write down any past property ownership, even a small share or an overseas property, and say whether you are buying alone or jointly.
- Work out your available deposit and where each part comes from. Keep money aside for legal fees, surveys, moving and property tax where applicable.
- Have a realistic purchase price range, income details and a list of regular financial commitments.
- Check your credit files for mistakes before applying. There is no UK-wide pass mark.
- Gather evidence of identity, address, income and deposit. A lender may request more after assessing your case.
Use our mortgage documents checklist for a fuller list. If you are ready to view properties or make an offer, ask whether an agreement in principle is appropriate. It is an early indication, not a mortgage offer.

We can discuss your mortgage options and what to prepare next. Your conveyancer should confirm tax and legal eligibility.

Check Count Ready before you enquire

First-time buyer mortgage requirements: common questions
Do I need a 5% deposit?
Some mortgages allow a 5% deposit, but this is not a rule for every lender or property. Your options depend on the purchase price, affordability and lender criteria. A larger deposit may change the products available; compare the full cost, not the rate alone.
Is there a minimum credit score for a first-time buyer mortgage?
There is no single UK credit score that all lenders use as a pass mark. Lenders review credit file information and apply their own criteria alongside affordability and other factors. Check your files for errors and discuss any missed payments or defaults with an adviser.
Does inheriting a property mean I am no longer a first-time buyer?
It may affect first-time buyer tax relief if you acquired a qualifying interest in a dwelling, even if you did not live there. The effect on a mortgage product or savings scheme can differ. Tell your conveyancer and mortgage adviser what you inherited, when and where.
Can I get a mortgage with someone who is not a first-time buyer?
Potentially, yes. A joint mortgage application can be assessed even if one applicant has owned before. Tax relief and scheme rules must be checked separately. For England and Northern Ireland first-time buyer SDLT relief, all purchasers must meet HMRC’s conditions.
Does an agreement in principle mean I qualify?
No. It gives an early indication based on information available at that stage. A full application, supporting documents, property valuation and lender checks still follow. Do not treat it as a guaranteed offer.
