Frequently asked questions
What is the rental yield in HA1?
The indicative gross rental yield in HA1 (Harrow) is 5.2% — the ONS mean private rent of £1,755/month for Harrow, annualised, divided by the £403,000 HM Land Registry median sold price. It is a gross figure (before mortgage interest, voids, management, maintenance, ground rent and tax) and is area-level, not address-level.
How is this yield calculated?
Gross yield = annual rent ÷ price. The rent is the ONS Price Index of Private Rents mean for the outcode's local authority (ONS PIPR, edition published 20 May 2026); the price is the median of recent HM Land Registry Price Paid sales in the outcode. Both are real published figures, but mixing an LA-level rent with an outcode-level price makes the result indicative — use it to compare areas, then check the exact property before you buy.
What about buy-to-let stamp duty in HA1?
Buy-to-let and second homes pay the additional-property SDLT surcharge — currently +5 percentage points on every band on top of the standard residential rates (England & NI). On the £403,000 HA1 median that is an upfront cost to include in your calculations. Use the HouseCheckup stamp-duty calculator with the additional-property toggle.
Are there flood, coal or subsidence risks that affect insurability in HA1?
flood: recorded nearby · coal: no point match · subsidence: Probable · radon: 1/6 For a landlord these are insurability and mortgageability questions, not just safety ones — a flood or subsidence flag can raise premiums or narrow the lender pool. This is an area-level screen at the representative point for HA1; risk varies street by street, so check the exact address before you offer.
