How to get the best buy-to-let mortgage rates

To secure the best buy-to-let mortgage rates, it’s important to improve your credit score, put down a larger deposit to reduce your loan-to-value ratio, and clearly demonstrate that the rental income will cover the payments.

Rates are often lower on two-year fixes compared to five-year deals, and repayment mortgages can sometimes be priced more competitively than interest-only, although the latter keeps monthly payments lower.

How can a mortgage advisor help?

Working with a mortgage advisor can make it much easier to find the best deal for your circumstances. Advisors search the market for you and often have access to lenders that aren’t available directly. More importantly, they can help you weigh up short-term rate savings against the bigger picture.

For example, an interest-only mortgage might mean lower monthly payments, but you aren’t reducing the loan balance. At the same time, a two-year fix may offer a cheaper initial rate but could lead to extra remortgaging costs compared to a five-year deal. An advisor can explain these trade-offs clearly and help you choose the option that works best for your long-term plans.

Typical interest rates for buy-to-let mortgages

The rate you could secure will depend on factors including the property value, the size of your deposit or loan-to-value (LTV), and the type of buy-to-let mortgage you want (personal or business).

It also depends on the type of mortgage you’ve chosen ( fixed or variable rate). One option is a tracker mortgageAs the name suggests, your rate can go up and down with a variable-rate mortgage, usually if the Bank of England base rate changes.

The alternative is a fixed-rate mortgage where your rate stays the same for an agreed period (e.g. five years). The rates can start slightly higher to protect the lender in case the Bank of England base rate spikes.

Why are buy-to-let mortgages more expensive?

Buy-to-let mortgages typically have higher interest rates than conventional residential mortgages as they’re generally perceived to represent a slightly higher risk for the lender. This is because of differences in eligibility criteria, which centre on rental income rather than employment income. Rental income is deemed, potentially, to be more volatile.

How loan-to-value affects your rate

As with any mortgage, having a larger deposit will usually help you to get a lower mortgage rate. Lenders usually require a larger deposit for a buy-to-let mortgage than a residential one. So, you’ll find plenty of deals if you have a 40-50% deposit, fewer if you have 20-30%, and none, currently, with a smaller deposit of 10%.

Repayment vs interest-only

Most mainstream lenders – including those featured in the rates table above – will quote the same interest rate regardless of whether you opt for interest-only or capital and interest as a repayment method for your buy-to-let mortgage.

Of the two choices, interest-only tends to be the more popular choice for buy-to-let investors as the payments will be lower – because they only include the interest element – and the property is usually used as the repayment vehicle to repay the original capital owed at the end of the term.

How to compare rates and deals

You can’t compare mortgage deals by looking solely at the advertised rate. The best – smartest – way to thoroughly assess all of the best interest rates is to seek the help of a buy-to-let mortgage broker.

They’ll be able to help you with:

  • Identifying the right lenders who are offering the best interest rate deals currently available for buy-to-let mortgages
  • Deciding what type of rate would best suit your circumstances
  • Looking more closely at each deal, what fees are attached and whether you can pay this upfront or add it to your mortgage
  • Preparing your application with all the necessary information and documentary evidence gives you the best chance of success – first time!

If you get in touch, we can arrange for a buy-to-let broker we work with to contact you and discuss your requirements in more detail.

Rates for HMO properties

Only around half of buy-to-let mortgage providers will lend against houses in multiple occupation (HMOs). Our table below provides a snapshot of the deals currently available, but please note that these are subject to change.

FAQs

Yes, a little. You’ll need a special purpose vehicle (SPV) mortgage, and these have slightly higher rates, as well as slightly higher fees to reflect the added complexity and paperwork.

When you let to buy, you’ll be taking on two mortgages simultaneously: one for the property you are letting, and a second for the property you’re buying to live in. These two mortgage interest rates are calculated separately.

Find out more in our guide to let-to-buy.

Not always. Rates and fees are two aspects of a mortgage that you’ll need to compare between lenders, and you shouldn’t look at either in isolation.
