What actually decides a Harrow 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
Harrow's housing market in 2026
The average property in Harrow sold for £546,655 over the past year, up 1% on the year before and 4% above the borough's previous 2022 peak of £527,692. Semi-detached homes were the most commonly sold property type at £657,595 on average, with terraced houses around Kenton averaging £570,247 and flats at £319,302.
Harrow setting a new price high, led by semi-detached demand around Pinner and Harrow on the Hill, means mortgage sizes here have grown faster than in many outer-London boroughs, a good prompt to check that existing life cover has kept pace.

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 Harrow: common questions
What rental yield can I expect in Harrow?
Average gross yield across Harrow is around 4.4%, with entry prices from about £490k. Yields vary meaningfully within the borough — Harrow on the Hill and Pinner 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 Harrow?
Most buy to let lenders want at least 25%. On Harrow's £490k entry price that is roughly £122,500, 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 Harrow?
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 Harrow?
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.
