Buy-to-let mortgages typically require a larger deposit than conventional residential mortgages and that can be a barrier for many would-be property investors.

However, it’s possible to buy a rental property with a small deposit if you have the right approach. In this guide, we’ll tell you which lenders require the lowest deposits and how to improve your chances of mortgage approval.

We’ll cover the following topics…

 How much deposit do you need for a buy-to-let mortgage?

Buy-to-let mortgages differ in that lenders often demand higher fees and interest rates due to perceived higher risk. A minimum deposit of 20-40% of the property’s value is often required, with 25% being common. Lenders may require higher deposits, up to 40%, based on the borrower’s financial profile.

Lenders also typically reserve the highest Loan-to-Value (LTV) deals for previously owned houses. If you’re purchasing a flat, maisonette, or any newly built property, you’ll likely require a larger deposit. For example, few lenders will accept less than a 25% deposit for a new build flat.

What’s the minimum deposit requirement?

A small number of lenders will consider applications with a deposit lower than 20%. Deposits of less than 10% are not out of the question but you would need to meet all of the other eligibility criteria in order to be successful.

Can you get a 100% LTV deal?

No, these types of mortgages always require a deposit. You’ll need to raise upfront capital if you want to invest in a rental property, and there are other costs to consider as well as your mortgage deposit, e.g. legal fees, letting agent fees, renovation costs and maintenance costs.

How to get a buy-to-let mortgage with a low deposit

What type of deposit will lenders accept?

There are various ways to raise capital, and you’ll need to provide proof of the source.

Your buy-to-let mortgage deposit can come from:

How your deposit amount affects your mortgage rate

Unfortunately, you’ll usually pay a higher mortgage rate if you have a small deposit. That’s because there are fewer lenders to choose from and the ones that are available see your application as a high risk that they need to mitigate.

After the end of your fixed-rate period or discounted-rate period, you can consider remortgaging. If you’ve saved money from the rental income of the property, you can use that to remortgage at a lower LTV so that you’ll have access to more lenders.

Loan to Value ratio (LTV):

Most lenders won't offer buy-to-let mortgages over a LTV of 80%.

Interest Cover Ratio (ICR):

Most lenders require rental income to be at least 125%-145% of the interest repayments for a buy-to-let mortgage.

Get started with a specialist buy-to-let broker to find out how much they could help you save on your monthly mortgage repayments.

Which lenders require the lowest deposit?

If you’re buying a house, the BTL lenders who’ll accept the lowest deposits include Darlington, Foundation Home Loans, and Vida Home Loans. For flats, Kent Reliance and Kensington Mortgages are among your best options.

Remember that when you have very few lenders to choose from, you can’t afford to be declined. For the best chance of approval, you should work with a broker to prepare your mortgage application and carefully choose the lender best suited to your situation.

Get matched with a buy-to-let mortgage specialist

For applications like these, it’s really helpful if your buy-to-let broker has previous experience with investors who have low deposits. They’ll know what lenders look for and how to optimise your application.
