A postcode yield table can help narrow a property search, but it cannot tell an investor what a particular home will earn. Property Investments UK’s Manchester guide, labelled as updated in February 2026, reports a gross yield of 7.9% for M14, followed by 7.2% for M13 and 6.8% for M11. These are the publisher’s comparison figures, not independently verified returns on completed investments.
Understand the calculation
The table pairs average monthly rents with average asking prices. That is different from comparing the agreed rent and completed purchase price of the same property. It also means the figures should not be described as net income after costs. The guide cites several data sources, including PropertyData and HM Land Registry, and identifies its update period. Anyone using it now should check whether more recent evidence is available.
Make the comparison specific
Before using a headline percentage in a budget, assemble a small set of genuinely comparable homes. Note the number of bedrooms, condition, furnishing and location for each one. Keep asking rents separate from rents known to have been agreed. A larger shared house and a smaller flat can sit within the same postcode while serving very different tenants and carrying different costs.
Write down the purchase assumptions too. A lower advertised price may reflect work that must be paid for before letting. For a flat, request the service-charge information rather than leaving an empty line in the forecast. These are due-diligence questions for the individual property, not conclusions that can be drawn from its postcode.
Test the cash position
MoneyHelper advises landlords to plan for gaps in rent and major repairs, and warns against assuming a sale will always repay the mortgage. Ask what happens to your cash reserve if an empty period and a repair occur together. Include borrowing costs and obtain advice on tax before treating any surplus as available income.
The useful outcome of a ranking is a better research shortlist. It is not proof that the highest-ranked area is suitable for every buyer, or that an individual property will reproduce the average. This replaces a short archive introduction with a dated, qualified explanation of the available comparison.
