At what LTV/with what deposit can I get a buy to let mortgage?

You can borrow up to 85% loan to value on a buy to let mortgage, which means you would need a deposit of at least 15% of the value of the property.

If you don’t have that amount in cash, you could go for a lower value property (which could still achieve a good profit), you could raise a deposit from equity in other property you own, or you could invest with someone who could contribute to the deposit with you.

Factors that may impact you getting a buy to let mortgage

  • Some types of poor credit
  • The value of the property being less than you expected

Understanding buy to let deposits and loan to values

Loan to Value, known as LTV, describes how much you want to borrow, expressed as a percentage of the value of a property, and, as a result, shows how much your deposit funds or equity must be.

For example, if a property is valued at £100,000 and you have £20,000 to put down as a deposit, you will require a mortgage of £80,000, which gives a loan to value of 80%.

Lenders offer their products at different LTVs, requiring different deposit amounts. Products commonly range from 50% to 80% LTV (wondering if you can borrow more than 80% LTV? See our 85% loan to value buy to let mortgage page).

You can always put in more than the minimum required deposit, which could get you a lower mortgage rate. The LTVs are there to give the maximum percentage of the property value the lender is prepared to lend.

Our specialist advisors are always happy to talk over anything BTL deposit or LTV related and answer any questions you might have. When you are ready to discuss, do not hesitate to contact us!

We can help you work out how much you can borrow with a cash deposit, or how you may be able to raise funds by borrowing against other property you own.

What our clients say about us

Frequently asked questions

The loan to value ratio reflects the level of risk a lender associates with lending their money.

If the LTV is lower, the lender won’t have to provide as much money towards the cost of a property, which reduces the level of risk they will take on. The risk is also reflected in the rates associated with the mortgage. Mortgage rates are generally lower when the LTV is low.

This means that it is important to discuss every option with your mortgage advisor. If you can provide slightly more of a deposit or top up your equity to a slightly higher LTV, the amount of buy to let mortgage products that you have access to may be larger. The rates may also be lower, meaning your monthly payments could be lower too.

The maximum LTV on a standard buy to let mortgage is currently 85%.

This is not a constant though, as sometimes lenders change their product offerings. It is also important to remember that, if you don’t have 15% of the property value in cash, you may be able to raise it from equity in other property you own.

If you are looking for a specialist buy to let product, e.g. an HMO mortgage, MUB mortgage, or limited company buy to let mortgage, the maximum LTV may differ.

There are no ‘good’ or ‘bad’ LTV rates. The LTVs that you have access to will depend on your circumstances, the value of your property and the amount of deposit or equity you have available.

On the whole, lower LTV rates offer more benefits to the borrower and less risk to the lender. This is because the lender doesn’t have to invest as much of their own money into the property, reducing the risk to them.

As a borrower, putting down a larger deposit means you are more likely to be able to access lower interest rates with lower monthly payments.

The minimum deposit for a buy to let mortgage is currently 15%.

Products that require a 25%-30% deposit or equity in the property are more common, as it is more beneficial for both parties. The lender has less risk and the landlord will have access to lower interest rates.

Wider criteria, relating to the security property, the rental income, and you as a borrower will influence the deposit amount.

Yes, low deposit buy to let mortgages currently require you to put down just 15% of the property value.

Some landlords may only be able to or want to put down the minimum deposit for a property, for various reasons. These may be circumstantial or strategic.

The more you can put down as a deposit, the cheaper your mortgage could be in the long term. This is because high LTV products typically have higher mortgage interest rates.

No, the deposit you need for a buy to let property can be as little as 15%, or any greater amount.

The amount of deposit that you put down against the mortgage will change the products that you have access to. With a 25% deposit, the number of products begins to widen considerably in comparison to those products available with a 15% deposit. At 40-50% deposit, or more, you will usually find that the whole market is available to you. Lenders generally do not reduce their rates any further once you get to 50-60% loan to value.

The amount you can borrow for a buy to let mortgage will generally depend on the rental income your security property can achieve.

Your personal income may also be a factor. Each buy to let mortgage lender will have specific criteria that will need to be met, in order to allow you to access a particular product.
