How loan to value affects the deal you qualify for
Typically, most buy to let lenders require a deposit of between 20% and 25% of the property’s value. With this kind of loan-to-value (LTV) ratio, you are likely to have a wide range of products to choose from. That creates competition among lenders and, subsequently, competitive rates.
With an LTV of 50% or lower, you may find you can secure the lowest BTL mortgage rates on the market.
If you’re looking for a buy-to-let mortgage with an LTV of 85% or above, it’s essential you apply through a specialist broker as your borrowing options will be limited by going it alone.
Typical BTL rates by LTV are:
- 50% – 59%: Under 4%
- 60% – 69%: 4% – 4.5%
- 70% -79%: 4.5% – 5%
- 80% – 89%: 5% – 6%
- 90% – 100%: 6% +
These are average rates but, as you can see in the table above, there are better deals available where your circumstances match a lenders’ lending profile more closely.

How repayment interest rates compare to interest-only
Most BTL mortgages are taken out on interest-only terms to help limit monthly outgoings, but they are available using the repayment method too.
Whether you opt for a repayment or interest-only mortgage, the rate you get will be the same, but the amount you pay will differ. Take a look at our rates table below to get an idea of the repayment buy-to-let mortgage deals available.

FAQs
As a rough guide, most landlords would expect to pay between 4% and 6% at the time of writing (January 2023). BTL mortgage rates are not calculated in the same way as residential rates.
The amount you can borrow and deal you can secure are based more on the rental profit you expect from the property rather than your personal income.
Other factors that will affect the rate you’re offered include:
- Experience as a landlord
- Loan to value (LTV)
- Credit score
- Portfolio size
Yes. These are commercial BTL mortgages which are unregulated and generally come with higher rates of interest.
But competitive rates are available if you know where to look and one other option could be to consider using a Special Purpose Vehicle (SPV) for your buy-to-let mortgage. Many lenders in this niche only accept applications via an intermediary.
Let-to-buy mortgages require you to have a BTL mortgage and residential mortgage at the same time.
Rates are calculated according to the lenders usual eligibility criteria, but each mortgage will affect affordability for the other.
Often, yes. Nobody works for free and where a mortgage is advertised as no-fee, the broker arranging the deal will usually receive a commission from the lender.
It’s not uncommon for the lender to offset this by charging a higher rate. The rates can also be higher if you’re a first-time landlord due to the increased risk the mortgage provider is taking on by lending to someone with no track record in BTL.
