Mortgage rates for buy-to-let properties can vary significantly based on factors like the lender, your credit score, and the size of your deposit. As of now, rates typically range from around 2% to over 5%. It's important to shop around and compare offers from different lenders, as some may have special rates for specific property types or locations. For the most accurate and current rates tailored to your situation, consider checking with an FCA-authorised mortgage adviser or visiting comparison sites. Always ensure that you're fully aware of all fees and terms associated with any mortgage product.
