Buy to let mortgage rates are usually a little higher than residential rates at the same loan to value, because lenders see rental property as higher risk. Within that, the rate you're offered comes down to a few things: how much deposit you have, the type of product, the fee you choose, the property, and whether you buy personally or through a limited company.
I won't quote live rates on this page, because they change too often to be useful here. What I can do is explain how lenders price buy to let, so you know what to look for, and then compare today's deals for your situation when you're ready.
Fixed rates follow the cost of money in the markets, while trackers follow the Bank of England base rate directly.
The bigger your deposit, the lower the risk to the lender and the better the rate.
Lenders adjust pricing to win or slow down business, which is why the best buy changes week to week.
Most landlords end up choosing between a handful of product types. Here's what each one means in plain English.
Your rate is set for two years, then you review. Good for flexibility, but usually stressed at a higher rate for the rent test.
The most popular choice with landlords. Five years of certainty, and lenders can often test the rent at the pay rate.
Tracks the Bank of England base rate plus a set margin. Payments go up and down, and charges for leaving early are often lower.
You pay just the interest each month and repay the loan at the end, usually from the sale. Lower monthly payments, but the debt doesn't go down.
Higher monthly repayments, but the mortgage is cleared by the end of the term. Some landlords mix the two as part and part.
For HMOs, multi unit blocks, holiday lets and limited companies. Different criteria and pricing to standard buy to let.
There's no right answer for everyone. It depends on how long you'll keep the property, how much rate movement you can absorb and how tight the rent calculation is.
The best buy to let deal isn't always the one with the lowest rate. It's the one with the lowest total cost over the time you'll keep it, that still passes the rent test and suits your plans.
Add the fee to the interest you'll pay over the fixed period. On smaller loans a no fee deal often wins.
Rates usually step down at 75%, 65% and 60% loan to value. A small extra deposit can move you into a cheaper band.
A great rate is no use if the rent doesn't pass that lender's stress test. We check both at the same time.
Specialist lenders and broker exclusive deals don't always show on comparison sites, and can beat high street rates.
If you might sell or refinance within a few years, early repayment charges matter as much as the rate.
Lenders reprice often, sometimes with a day's notice. Once we find the right deal, we can usually secure it fast.
The higher rate works out about £500 cheaper over the two years. Illustrative rates only, not current offers.
Every product has rules about leaving early and what happens when the deal ends. It's worth knowing them before you choose.
Most fixed rates charge a percentage of the loan if you repay or switch during the deal, often sliding down each year. If you might sell, look for lower or no charges.
When a fixed or tracker period ends, you move to the lender's standard variable rate, which is usually much higher. Few landlords should sit on it for long.
You can take a new deal with your current lender or move to a new one. Read our product transfer vs remortgage guideand our buy to let remortgage page.
Lenders see rental property as higher risk than a home you live in, and they hold more capital against it. That's usually reflected in a slightly higher rate at the same loan to value.
It changes almost daily and depends on your deposit, the property, how you own it and the fee you're happy to pay. The lowest headline rate often isn't the cheapest overall, so we compare the full cost for you.
Five year fixes give longer certainty and often help you pass the rent test, because lenders can test them at the pay rate. Two year fixes give flexibility if you expect rates to fall or plan to sell.
Usually, yes. You'll pay interest on it over the term and it nudges the loan to value up, which can matter if you're close to a rate band.
Often slightly, though the gap has narrowed a lot. For many higher rate taxpayers, the tax savings outweigh a small difference in rate.
Around six months before your fixed period ends. Many lenders let you secure a new deal that far ahead, so you're protected if rates rise before your current deal finishes.
