Welcome to the Proplytics Investor Monthly. Your data-led briefing on what's moving in UK property investment.
Newcastle now leads the country on rental yield at 9.7% gross, with Leeds close behind at 9.6% and Sunderland returning 8.8% on one-bedroom flats. Over the same period the average London home lost 1.5% of its value to settle at £534,375. The distance between where rental income is strongest and where capital is most expensive has rarely looked this wide, and for portfolio investors that gap is the story of the month.
The yield map has tilted north
This is not a one-month blip. The North East recorded annual price growth of 3.1%, taking the average home to £181,703, while the North West rose 3.0% to £248,304. Northern Ireland leads the whole UK at 7.6% over the year. At the other end, the South East fell 2.1% to £382,704 and remains the weakest region in the country, with London down 1.5%.
The reason is affordability. Lower entry prices in the north and the devolved nations keep mortgage costs within reach of more buyers and tenants, so demand holds where it has thinned in the higher-priced south. Higher prices in London and the South East magnify every movement in mortgage rates, which is why those markets feel the squeeze first.
For a portfolio the implication is concrete. Capital parked in a single southern holding is working harder for you in Newcastle, Leeds or Sunderland, both on the monthly rent it earns and on the direction of its price.
Rents keep rising as smaller landlords step back
Average UK rents reached £1,340 a month in May, up 2.5% over the year and the strongest annual growth recorded so far in 2026. Ten of the twelve regions saw rents rise. A handful of places ran much hotter than the average, with Carlisle up 9.1%, Kilmarnock up 9.0% and Halifax up 6.5%.
The driver is supply, and supply is tightening for structural reasons. The Renters' Rights Act took effect on 1 May 2026, ending Section 21 no-fault evictions and converting fixed-term tenancies into open-ended periodic ones. Set alongside the Section 24 tax rules, which tax rental income before finance costs are deducted, and the rollout of Making Tax Digital for landlords earning above £50,000 from April, the running cost of being a part-time landlord has climbed. Many are selling or switching to short lets. Fewer rental homes against steady tenant demand points in one direction for rents.
That result cuts both ways. Income prospects for committed landlords are improving, but the cost of getting possession wrong has risen too. Breaches of the new rules can bring civil penalties of up to £7,000, and serious offences can reach £40,000. The advantage now sits with landlords who can meet higher standards and manage tenancies properly.
Borrowing costs are easing, slowly
The Bank of England held the base rate at 3.75% on 30 April and is widely expected to hold again on 18 June. Swap rates, which set the price of fixed mortgages, have drifted lower over the past month as inflation data softened and energy-market tension calmed. The lowest five-year fixes have come back to around 4.48%.
That is welcome, but rates remain well above where they sat before the early-2026 energy shock. Anyone rolling off a deal fixed in 2021 or 2022 is still refinancing onto a materially higher payment. Forecasters are split on where rates go for the rest of the year, so the useful question is not whether borrowing gets cheaper. It is whether the income on a given property covers its new cost of debt with room to spare.
What this means for your portfolio
Three practical moves stand out this month.
First, run the refinance maths early. If you have a fix maturing in the next six months, model the new payment against today's rent now rather than waiting for renewal. A property that cleared its costs comfortably at a 2% rate can look marginal at 4.5%, and it is better to find that out before your lender does.
Second, take the regional question seriously. The income and growth case for the north and the devolved nations rests on a full year of data, not a single month's print. If your capital sits in a soft southern market, the cost of simply holding is real, and a rebalance toward higher-yielding regions deserves a proper look.
Third, treat compliance as part of the investment case rather than an afterthought. The homes that earn well over the next few years will be the ones held by landlords who can satisfy the new standards and handle possession correctly. That favours scale, sensible structure and good record-keeping.
For investors weighing a regional move or stress-testing a refinance, the Investor Pro report brings yield, capital growth and rate exposure together at postcode and regional level, so you can compare markets on the same evidence instead of on headlines.
The headline base rate may be holding steady, but underneath it the map of where UK property income is strongest is being redrawn. The investors who do well from here will be the ones who follow the data rather than habit. For the full set of regional figures and the analysis behind them, visit proplytics.kabware.co.uk.
