How many Buy to Let properties can you own?

There is no fixed legal limit on the number of Buy to Let properties you can own. However, most lenders impose limits on how much exposure they are willing to have with a single borrower. Some lenders restrict borrowers to one Buy to Let property. Others may allow three or more, depending on income and experience. Portfolio landlords may need to spread borrowing across multiple lenders. If you are unsure which lenders are still available to you as your portfolio grows, our mortgage advisers can assess your position and identify the most suitable next lender.

Repayment or interest-only mortgages

With a repayment mortgage, your monthly payments gradually reduce the balance, meaning you will own the property outright at the end of the term — assuming all payments are maintained. Interest-only mortgages require you to pay only the interest each month. Many landlords prefer this option as it keeps monthly costs lower and allows flexibility during void periods. It’s important to remember that interest-only mortgages do not repay the capital. A clear repayment strategy should always be in place.

What deposit do I need for Buy to Let?

Most Buy to Let mortgages require a minimum deposit of 25% of the property value. Some specialist lenders may require larger deposits depending on the property type, rental yield, or borrower profile.

Is Buy to Let a good investment?

Buy to Let property can be profitable if approached carefully, but it is not risk-free. Landlords must be prepared for void periods, maintenance costs, and changes in regulation or taxation. As with any investment, you should never commit funds that you cannot afford to lose. Proper planning, realistic expectations, and expert advice can significantly improve the likelihood of long-term success.
