Second Home Mortgage FAQ
Everything you need to know about financing a second home in the UK, from deposits and interest rates to the stamp duty surcharge.
Second home mortgages are usually assessed on affordability alongside your existing mortgage, so lenders check you can comfortably afford both. Maximum loan-to-value is often lower than for a main residence, deposits are typically larger, and interest rates can be slightly higher to reflect the additional risk to the lender.
Yes. In England and Northern Ireland, buyers of an additional residential property pay standard Stamp Duty Land Tax plus a 5% surcharge on the full purchase price. The surcharge applies to holiday homes, buy-to-let purchases and second homes bought before an existing main residence is sold, though it may be reclaimed if the previous main home sells within 36 months.
Most lenders ask for a minimum deposit of 15% to 25% for a second home, though some require more depending on the property type, location and your overall financial circumstances. A larger deposit generally unlocks a wider choice of lenders and more competitive interest rates.
Some lenders offer interest-only second home mortgages, particularly where the property will be let out as a holiday home, but you will usually need to show a credible repayment strategy for the capital, such as savings, investments or an intended future sale of the property.
It can. Lenders generally factor in your existing mortgage commitments when assessing affordability for a second home, and vice versa. Total borrowing across both properties needs to fit within what you can reasonably afford based on your income, outgoings and any rental income the second property may generate.
Not usually. A standard second home mortgage assumes the property is for personal use, while a holiday let mortgage is a specialist product designed for properties that will be rented out to paying guests. Holiday let mortgages are typically assessed on projected rental income and often carry different rates and criteria.
