Best Buy to Let Mortgage Rates UK 2026: Top Landlord Deals Compared

Buy to let mortgage rates are under significant pressure in April 2026, rising sharply due to the Middle East conflict. Here's the full picture for landlords — including whether BTL still makes financial sense. Updated April 2026

Best Buy to Let Mortgage Rates — April 2026

TermBest RateAvg RateChange Since Jan 2026
2-Year Fixed~5.0%5.29%+0.63%
5-Year Fixed~4.9%5.32%+0.66%
Tracker~5.5%5.8%+0.5%

According to Moneyfacts, buy-to-let fixed rates over both 2 and 5-year terms have increased sharply since the start of the Middle East conflict in March 2026. Overall product choice has fallen by approximately 1,300 deals since the start of March.

The Rental Stress Test — Can Your Property Still Pass?

Most lenders stress-test buy to let mortgages at a higher notional rate (typically 5.5-6.5%) and require rent to cover 125-145% of that. Here's what that means in practice:

Property ValueLoan (75% LTV)Rent Needed (125% @ 5.5%)Rent Needed (145% @ 5.5%)
£200,000£150,000£860/month£998/month
£250,000£187,500£1,074/month£1,247/month
£300,000£225,000£1,289/month£1,497/month
£400,000£300,000£1,719/month£1,996/month

In many UK regions outside London and the South East, rents are not keeping pace with these requirements, making new BTL purchases harder to finance. Landlords with existing mortgages at lower historic rates face a stark reassessment when they come to remortgage.

Buy to Let: Still Worth It in 2026?

Buy to let is still viable in 2026 but requires much more careful financial modelling than in the low-rate era. High-yield areas (Northern England, Scotland, Midlands) are more profitable than low-yield areas (London, South East). Portfolio landlords with low LTVs are better positioned than those with high leverage.

KAELTRIPTON VERDICT
Buy to let mortgage rates are rising sharply in April 2026. Landlords remortgaging in 2026 will face significant payment increases. New purchases need careful analysis — only high-yield properties in strong rental markets can currently generate positive cash flow at today's rates.
Rating: ★★★☆☆ Challenging but Viable in Right Areas

Q: What is the rental income requirement?
