3-year fixed buy-to-let rates, purchase and remortgage.

Three-year buy-to-let fixes cover both purchase and remortgage, but they remain a thin tier in the UK BTL market. Most lenders concentrate their product ranges at 2 and 5 years and introduce 3-year products intermittently, typically when funding conditions or competitive positioning make them worthwhile. The result is that availability fluctuates: these products appear and are withdrawn without announcement, and the table above can be empty for stretches before a fresh batch lands in the nightly ingest.

When 3-year fixes are available, they occupy an awkward stress-test position. Like 2-year products, they typically attract the harder ICR assessment — pay rate plus 2% or a notional floor around 5.5% — rather than the softer stress applied to 5-year fixes. That means a landlord remortgaging with tight rental yield may find borrowing capacity identical to a 2-year deal despite the extra year of commitment. The appeal is behavioural as much as financial: three years maps neatly onto planning cycles, rent reviews and letting arrangements in a way that two years sometimes doesn’t.
