UK Property Investment in 2024/25 — Key Facts

The UK property market has faced a combination of higher mortgage rates, increased stamp duty for additional property purchasers, Section 24 mortgage interest restrictions, and rising CGT rates — all of which have materially changed the economics of property investment compared to five years ago.

Our stamp duty calculator shows the full SDLT liability for any buyer type, while our rental yield calculator helps you assess whether a potential investment property actually stacks up financially after all costs are considered. We strongly recommend using both together when evaluating a purchase.

For landlords selling property, our capital gains tax calculator uses the October 2024 revised rates (18%/24% on residential property) and includes the Private Residence Relief calculator for properties that were once your main home.
