What actually decides a Kingston upon Thames 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
Kingston upon Thames's housing market in 2026
The average property in Kingston upon Thames sold for £588,860 over the past year, down 1% on the year before and broadly in line with the borough's 2022 peak of £593,178.

Kingston's prices sitting almost exactly at their 2022 peak means buyers here aren't benefiting from the discounts seen elsewhere in London, all the more reason to make sure mortgage protection is reviewed at the point of purchase rather than assumed to be cheaper than it actually is.

What our clients say
I have used Mortgage International a few times and they have always been very helpful, professional and reasonable. I would highly recommend and will always use them and recommend everyone does too.
Roger has been great to work with over the last few years, I got my first mortgage with him and have used him for our remortgages since. He was always quick to respond and explained everything clearly.
Roger assisted me in purchasing my first home during lockdown. He was helpful and provided great guidance during this process, especially as a first time buyer. I have since used him to remortgage too. Would recommend his services.
Buy to let in Kingston upon Thames: common questions
What rental yield can I expect in Kingston upon Thames?
Average gross yield across Kingston upon Thames is around 3.8%, with entry prices from about £580k. Yields vary meaningfully within the borough — Kingston Town and Surbiton 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 Kingston upon Thames?
Most buy to let lenders want at least 25%. On Kingston upon Thames's £580k entry price that is roughly £145,000, 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 Kingston upon Thames?
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 Kingston upon Thames?
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.
