Rents, Prices and Yields in the Local Market
Wellingborough sits within the North Northamptonshire council area, where the ONS recorded an average home price of £258,000 in July 2026, up 2.9% on the year. Rents have grown faster still.
Source: Office for National Statistics, August 2026. UK growth calculated from the published £1,348 and £1,400 averages.
Gross yield, meaning annual rent divided by purchase price, gives a quick first view of returns. Using the ONS averages, the area as a whole works out at roughly 4.6%.
| Property type | Average price | Average rent | Gross yield |
|---|---|---|---|
| Flat or maisonette | £119,000 | £796 | 8.0% |
| Terraced | £205,000 | £965 | 5.6% |
| Semi detached | £254,000 | £1,029 | 4.9% |
| Detached | £411,000 | £1,331 | 3.9% |
Calculated from ONS average prices (July 2026) and rents (August 2026). Indicative only.
Flats show the highest headline yield, but they often come with leasehold service charges and ground rent that eat into returns. Terraced houses tend to offer a steadier balance of entry price, rent and running costs.
Personal Name or Limited Company?
Ownership structure is the biggest business decision you will make. Individual landlords and companies are taxed in very different ways, and those differences are widening.
| Factor | Personal ownership | Limited company |
|---|---|---|
| Tax on rental profit | Income tax at the new property rates from April 2027, starting at 22% in the basic band | Corporation Tax at 19% up to £50,000 profit, 25% above £250,000 |
| Mortgage interest | Tax credit at the basic rate (20%, rising to 22% from 2027 to 2028) | Usually deductible as a business cost |
| Taking money out | Profits are already yours | Dividends taxed at 10.75% or 35.75% from April 2026 |
| Setup and admin | Simpler, fewer filings | Company accounts, filings and higher running costs |
The government’s technical note on new rates for property, savings and dividend income sets out exactly how these changes apply and when they start.
Many investors who choose the company route set up a separate special purpose vehicle that holds only property, rather than buying through their trading business. Lenders generally prefer this, and it keeps the two sets of accounts cleanly apart.
From 6 April 2027, individual landlords will pay property income tax at 22% for basic rate, 42% for higher rate and 47% for additional rate income.

Making Tax Digital: The New Admin Reality
Making Tax Digital for Income Tax now covers many landlords, not just sole traders. If you hold property personally, you will need compatible software and quarterly updates once your qualifying income passes the threshold.
| Qualifying income (tax year) | Required from |
|---|---|
| Over £50,000 (2024 to 2025) | 6 April 2026 |
| Over £30,000 (2025 to 2026) | 6 April 2027 |
| Over £20,000 (2026 to 2027) | 6 April 2028 |
Qualifying income combines self employment and property income before expenses. HMRC’s eligibility checker for the new digital reporting rules explains how to work out your position.
Business owners who already run cloud accounting software are well placed. Keeping your personal and property finances organised, as covered in our personal finance advice aimed at business owners, makes the switch far easier.
Run Your Rental Like a Proper Business
The landlords who do well treat each property as a small company with its own budget, cash flow and compliance calendar. Build these habits from day one:
- Separate bank account: keep rent and costs apart from your trading business
- Cash reserve: hold enough to cover repairs and at least a few months without rent
- Compliance diary: track gas safety, electrical checks, deposits and licensing dates
- New tenancy rules: since 1 May 2026, tenancies in England are periodic and section 21 has ended
- Registration: a national landlord database begins rolling out from late 2026
A good letting agent takes much of this weight off your shoulders and keeps tenants happy. Daira P., reviewing Progressive Lets on Google, praised a team member for making the process swift and easy, with quick replies to every email.
Responsive management keeps good tenants in place, and fewer void months protect your yield.

- Get a mortgage agreement in principle for your chosen structure
