Buy To Let Mortgages

Updated: Apr 5, 2023

What is a Buy To Let mortgage?

A buy to let mortgage is comparable in many ways to a residential mortgage. There are however some notable differences….firstly the interest rate is typically higher and you usually are required to put down a larger deposit.

Lenders will look at the expected rental income and don’t assess the mortgage on your personal income as they would with a typical residential mortgage. If you want a mortgage for a property you are going live in, a lender will look at many factors, including your personal income and expenditure to help decide if they are happy to make an offer.

The harsher conditions reflect the higher risks attached to buy to let mortgages as statistically borrowers are more likely to default on a buy to let mortgage than residential mortgages.


What is the maximum amount I can borrow to purchase a buy to let property?

 Most lenders will allow you borrow up to 70% of the value of the property. This will be conditional on the potential rent on the new property.


What do I need to know when buying a rental property?

Property is traditionally a good investment and a buy to let makes it possible to boost your monthly income whilst investing for the long term.

So long as the rent paid to you covers or exceeds your monthly mortgage payments, you could make a tidy profit.

You might also make a nice return when it comes to selling up but like all investments, there are the usual risks attached to buy to let.

Seeking out the right property in the the most appropriate location is important when deciding on a buy to let property.

Students for example are likely to want an affordable property in proximity to a university whilst families will be particularly keen to rent a property having a garden and to be near schools and other amenities.


Can I afford a buy to let property?

Generally, lenders determine how much you can feasibly borrow by looking at the property's overall value and the expected rental income.

It's usual practice to build in a safeguard too. This allows for latent costs such as the property occasionally being empty, paying estate agency fees, taxes and expense on maintenance. It is calculated by using what's known as the interest times cover ratio. The Interest times cover ratio determines the amount the lender would like the rental income to be, to cover the mortgage and other costs.

Regulation changes of late mean these calculations have got more stringent. Lenders will also 'stress‒test' the mortgage, to make sure that an increase in interest rates won't cause any problems and you will still make a profit. The minimum stress test rate is usually 2% above the actual rate.


Will personal income be factored into assessment for Buy to let mortgage?

Some lenders will take into consideration your personal income if the stress-tested monthly rental calculation explained above falls short. They will assess how much you earn compared to all you spend, including your residential mortgage, household expenditure and rental property costs.

Should you have additional income after covering all your outgoings, these lenders will combine it with expected rent to calculate the maximum amount you can borrow.


What if I am a professional landlord?

If you already own 4 or more properties, or intend to further extend your portfolio, there are now additional regulatory requirements for lenders to factor in to their assessments. The regulation is not arbitrary, but some examples include the lender's relationship with the borrower, how much experience the borrower has as a landlord, and a view of the borrower's overall property portfolio.
