Mortgage tips for first-time buyers in 2026

Getting a mortgage as a first-time buyer in 2026 looks very different from how it looked five years ago. Interest rates are well above the 2010s norm, lenders apply tougher affordability stress tests, and the products that suit a 5%-deposit buyer have multiplied. This guide covers the practical decisions that move the dial — not generic advice.

Start with the affordability calculation that actually matters

Lenders' headline maximum is usually 4.5× your annual income. The number you should plan around is the monthly repayment, not the maximum loan. Use any major lender's online calculator at the rate you would actually be paying — not the cheapest 2-year fix — and assume rates could rise by 1 to 2 percentage points before your fix ends.

If the monthly figure is uncomfortable at today's rates plus 1%, the property is too expensive for your situation. That is true even if the lender will technically lend you the money.

Fix length: 2 years, 5 years, or longer?

Two-year fixes give you cheaper short-term rates and the flexibility to remortgage when rates fall. Five-year fixes lock in certainty and avoid arrangement fees on the next deal. In 2026 the gap between 2-year and 5-year fix rates is small enough that the decision really comes down to your view on where rates are heading and how stable your career and household situation is over the next five years.

If you expect to move within three years, a 2-year fix usually wins. If you are settling in, the 5-year fix removes a chunk of paperwork and uncertainty.

The 90% loan-to-value step

The single biggest rate jump for first-time buyers is between 90% LTV and 95% LTV. If you can find an extra 5% of the purchase price (whether by saving longer, a family gift, or buying a slightly cheaper property), you typically save 0.3 to 0.6 percentage points on the rate — which over a 25-year mortgage is tens of thousands of pounds.

The next big steps are at 85% and 75% LTV. Below 75% LTV, rate improvements get marginal.

Decision in principle is not a guarantee

A Decision in Principle (DIP) tells you a lender is willing to consider lending you a given amount. It does not bind the lender, does not survive material changes to your circumstances, and does not commit them to the actual property you find. Get one before viewings — estate agents now routinely ask — but treat the number as guidance, not a promise.

Watch the arrangement fees

The cheapest headline rate often comes with a £999 or £1,495 product fee. On smaller mortgages (under £200,000), a slightly higher rate with no fee is often cheaper overall over the fix period. Brokers do this maths automatically; if you are going direct, do it yourself.

Five things lenders care about that you might not

• Recent credit applications. Multiple credit-card or loan applications in the months before mortgage application can hurt your score. Stop applying for new credit 3 to 6 months before you start the process.
• Buy-now-pay-later. Klarna, Clearpay, and similar now appear on credit files and lenders read them as short-term consumer credit. A history of using them does not automatically disqualify you, but a current outstanding balance counts as debt.
• Gambling transactions on bank statements. Lenders look at 3 months of statements. Regular betting outgoings get flagged even if the net amount is small. Pause for a quarter before applying.
• Overdraft use. Living in your overdraft suggests you are stretched. Stay out of it for at least 3 months before applying.
• Self-employed income evidence. Most lenders want 2 to 3 years of accounts or SA302s. If you went self-employed recently, this is the structural blocker — you may need to wait until you have the history.

Broker vs going direct

A whole-of-market broker has access to lenders and products you cannot reach directly — including smaller building societies that often have the best deals for unusual circumstances (self-employed, mixed income, non-standard property). The fee is typically £0 to £500, often paid by the lender via procurement fee rather than by you. For most first-time buyers, a broker pays for themselves.

Go direct only if you are confident your situation is vanilla and you have time to compare every major lender yourself.

Don't forget the costs around the mortgage

The mortgage is not the only cost. Budget for:

• Stamp Duty Land Tax (often zero for first-time buyers under £300,000)
• Solicitor / conveyancer fees (£1,000–£2,000)
• Survey (£400–£1,500 depending on level)
• Mortgage valuation (often free, sometimes £200–£500)
• Land Registry fee (£150–£500)
• Moving costs (£500–£2,000)

All in, expect £3,000 to £6,000 of upfront costs on top of your deposit for a typical first-time purchase outside London.

Before you commit to an offer, check whether the asking price is reasonable and have a negotiation strategy ready.
