What actually decides a Wandsworth buy to let application
Yields here usually clear the interest cover ratio on a 75% loan, though not always at higher-rate tax. The deciding factors tend to be the product’s stress rate and whether you hold personally or through a limited company.
How we approach it
- →Comparing the 125% basic-rate and 145% higher-rate cover tests against your actual position
- →Five-year fixes, where the lower stress rate can materially increase borrowing
- →Whether a limited company structure improves both the tax position and the cover test
- →Product fees weighed against rate — a fee-free product is not automatically cheaper
Wandsworth's housing market in 2026
The average property in Wandsworth sold for £813,572 over the past year, down 1% on the year before and 3% below the borough's 2023 peak of £835,613, a relatively modest correction compared with neighbouring boroughs. Flats sold for £554,926 on average, with terraced houses around Battersea and Earlsfield averaging £1,200,601 and semi-detached homes reaching £1,973,591.
Wandsworth's young, family-forming population, many moving from Clapham flats into Earlsfield terraces, means mortgage sizes, and the life cover needed to match them, tend to step up sharply at exactly the point most families start one.

Buy to let in Wandsworth: common questions
What rental yield can I expect in Wandsworth?
Average gross yield across Wandsworth is around 3.5%, with entry prices from about £700k. Yields vary meaningfully within the borough — Battersea and Clapham will not price the same way. Gross yield ignores voids, management, maintenance and finance costs, so treat it as a starting comparison rather than a return.
How much deposit do I need for a buy to let in Wandsworth?
Most buy to let lenders want at least 25%. On Wandsworth's £700k entry price that is roughly £175,000, plus stamp duty at the higher additional-property rates and purchase costs. Some lenders go to 80% loan-to-value, though rates are higher and the rental cover test becomes harder to satisfy.
Should I buy through a limited company in Wandsworth?
It depends on your tax position rather than the borough. Higher-rate taxpayers often find a limited company more efficient, because mortgage interest is a deductible business expense rather than attracting the restricted relief that applies to personally-held property. Company products usually carry higher rates and fees, so the comparison has to be run on your actual numbers. We are not tax advisers — we will model the mortgage side and recommend you take accountancy advice on the rest.
Will the rent cover the mortgage in Wandsworth?
Yields here usually clear the interest cover ratio on a 75% loan, though not always at higher-rate tax. The deciding factors tend to be the product’s stress rate and whether you hold personally or through a limited company.
