Stamp Duty (SDLT)
Stamp Duty Land Tax (SDLT) is a major cost when buying UK residential property — particularly for investors, second-home buyers, and non-UK residents who face additional surcharges.
Use our free calculator to estimate how much SDLT you’ll owe based on the latest rates, property value, and your individual circumstances. We account for the 5% ‘additional properties’ surcharge and the 2% non-resident surcharge where applicable.
A Smarter Way to Access Property — Without Paying Stamp Duty Yourself
When you invest through Housemartin, you're not buying a property yourself, you're lending to a company that acquires the property on your behalf. That company pays all the upfront costs, including stamp duty, using the capital raised through the loan.
Unlike buying property yourself, where stamp duty is an unrecoverable cost, Housemartin loans are structured so that when you exit, a new investor buys you out at a price that reflects those original purchase costs. This means your share of the stamp duty, and other fixed costs, is typically recouped on resale via our Exchange.
- No personal SDLT or surcharges
- Fixed costs recovered when resold to another investor on our Exchange
- Monthly income, tax-free via ISA or SSAS
- Fully managed, socially beneficial properties on long-term inflation linked leases
