Buy to Let mortgage borrowing guidelines:

How much can I borrow?

In most cases, you will need to put down a 10% to 20% deposit depending on the mortgage lender.  The maximum is 90% loan to property value, meaning on a £100,000 property you would need to put down £10,000.

So how are Buy to Let mortgages calculated?

Buy to Let mortgages are calculated on whats called the rent to interest cover calculation.

This means monthly rental income needs to be a percentage higher than the monthly interest only mortgage payment.  This percentage varies between mortgage lenders but normally monthly rent needs to be between 10% and 30% higher.

For example if the interest only monthly mortgage payment was £500, and the rent to interest cover was set at 125%, then the monthly rental required would be £625. 

If the monthly rental income does not meet this required figure then the overall mortgage lending would be set at a lower percentage loan to value.  This is because the monthly interest mortgage payment will automatically be lowered if the loan is lessened.

Who will assess the potential monthly rental figure and the property value?

An independent valuer (surveyor) appointed by the mortgage lender, who works in the local area and has a good knowledge of the local rent potential and residential values.

So do most people borrow on an interest only basis?

Yes, in the vast majority of cases because people want their capital to stretch further and maximise capital for further purchases.  This means they can maximise any property potential.

Does it matter what type of tenant is in the property?

Yes, only certain mortgage lenders will lend to certain tenant types.  DSS tenants and asylum seekers for example are more difficult to fund.

Does it matter what type of property?

Again yes, certain mortgage lenders will only fund certain property types.  It therefore makes sense to explore funding options before committing to any purchase.

What about if your borrowing as a limited company?

Many people do set up limited companies to invest in property for tax reasons.  Mortgage lenders have recognised this fact, and a proportion will allow limited company borrowing.  Investors should however be aware that limited company borrowing will tend to be slightly more expensive.

Is a problem if I do not have a clear credit history?

No, Buy to Let mortgages are available for individuals with adverse credit histories, but again investors should be aware these will be more expensively priced.
