How do rental yields in Hertsmere compare with the rest of the East of England?

Across the region, gross yields run from 3.2% in Uttlesford to 6.1% in Norwich. These are gross yields, before costs and tax.
Why is the net yield in Hertsmere lower than the gross yield?
Gross yield counts every month's rent and no costs. On a property at Hertsmere's average price and rent, one empty month a year costs £1,829 in lost rent, letting agent fees at 12% cost £2,414 and repairs at 5% of rent cost £1,006. That takes the yield from 4.0% to about 3.0%, a gap of 1.0 percentage points. Both yields are before mortgage costs and tax, which reduce the return further, as would any service charge or ground rent.
Is Hertsmere 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, Hertsmere's gross yield ranks 228th of 316 local authorities in England and Wales and 29th of 45 in the East of England. With a 25% deposit and a 4.5% interest-only mortgage, a property at the average price and rent would lose about £152 a month before tax after letting, repair and void costs. Rent stops covering those costs and the interest at a mortgage rate of about 4.1%. Individual properties vary widely, so test a specific deal before relying on an area average.
