What is a second home mortgage?
A second home mortgage is a loan secured against a residential property that you intend to use yourself — as a holiday home, a base near family, or a property for personal use — rather than a property you plan to let out. This is the key distinction from a buy-to-let mortgage, which is assessed on rental income rather than your personal income.
Because you're already committed to your main mortgage or rent, lenders assess a second home application more cautiously. They'll want to see that you can comfortably afford both sets of payments at the same time, not just the new one.
How second home mortgages differ from your main residence mortgage
Larger deposit
Most lenders ask for a bigger deposit on a second home than they would on a main residence — typically starting from around 15%, though many lenders prefer 25% or more depending on the property and your circumstances. A larger deposit generally opens up better rates.
Stricter affordability checks
Lenders will look at your income, your existing mortgage or rental commitments, and any other debts to make sure you can service both properties. Some lenders factor in the total borrowing across both mortgages when calculating what you can afford.
Rates can be higher
Second home mortgages are sometimes priced slightly higher than standard residential mortgages, reflecting the additional risk lenders take on. Not every lender offers second home products, so working with a broker who knows which lenders are active in this space matters.
Stamp Duty on a second home
If you already own a property and you're buying another one, you'll usually pay the 5% Stamp Duty Land Tax surcharge on top of the standard rates. This applies to the whole purchase price on properties over £40,000, not just the amount above a threshold — so it's a significant cost to budget for alongside your deposit, legal fees and survey costs.
If you're replacing your main residence and sell your previous home within 36 months, you may be able to reclaim the surcharge. If you're planning to let the property out rather than use it yourself, you'll usually need a buy-to-let mortgage instead — see our buy-to-let mortgage page for how that's assessed differently.
Can I use equity from my main home?
Some buyers release equity from their current home through remortgaging to help fund the deposit on a second property. This can work well if you have significant equity built up, though it means increasing the borrowing on your main residence. We can talk you through whether this or a standard second home mortgage makes more sense for your situation.

Frequently asked questions
How much deposit do I need for a second home?
Most lenders ask for at least 15%, though many prefer 25% or more. The exact figure depends on the lender, the property, and your overall financial position.
Can I get a second home mortgage if I still have a mortgage on my main home?
Yes, this is the most common scenario. Lenders will assess whether your income can support both mortgages comfortably.
Is a second home mortgage the same as a buy-to-let mortgage?
No. A second home mortgage is for a property you intend to use yourself. If you plan to rent the property out, you'll need a buy-to-let mortgage, which is assessed differently based on expected rental income.
Do I have to pay the Stamp Duty surcharge on a second home?
In most cases, yes — the 5% surcharge applies if you already own a residential property. There are some exemptions, including replacing a main residence, so it's worth checking your specific situation.
