Both figures are before mortgage costs and tax.

How do rental yields in Swansea compare with the rest of Wales?
Swansea's gross yield of 5.0% is 0.6 points above the median of 4.4% for the 22 local authorities in Wales, and 0.6 points above the England and Wales median of 4.4%. Across the region, gross yields run from 3.1% in Powys to 5.8% in Merthyr Tydfil. These are gross yields, before costs and tax.
Why is the net yield in Swansea lower than the gross yield?
Gross yield counts every month's rent and no costs. On a property at Swansea's average price and rent, one empty month a year costs £852 in lost rent, letting agent fees at 12% cost £1,125 and repairs at 5% of rent cost £469. That takes the yield from 5.0% to about 3.8%, a gap of 1.2 percentage points. Both yields are before mortgage costs and tax, which reduce the return further, as would any service charge or ground rent.
Is Swansea good for buy-to-let?
RealYield does not rate areas as good or bad investments, because the answer depends on the property, the price paid and your own circumstances. On the published averages, Swansea's gross yield ranks 88th of 316 local authorities in England and Wales and 6th of 22 in Wales. With a 25% deposit and a 4.5% interest-only mortgage, a property at the average price and rent would make about £71 a month before tax after letting, repair and void costs. Rent stops covering those costs and the interest at a mortgage rate of about 5.0%. Individual properties vary widely, so test a specific deal before relying on an area average.
