We have 2 rentals at the end of the Elizabeth line in London. Never raised the rent. Tenants have been in each for 6 years. One 2 bed house goes for £1120 and the other 3 bed is £1300. They were always competitively priced but now they are each quite a bit below market rates. For context, a rather grim two bed flat (not house, local authority building, no garden) is on for £1500 - so £400 less than the two bed house and a 3 bed on the same road as our 3 bed was recently advertised for £1900, £600 less than we are charging, and was snapped up. During Covid we let tenants off with at least a couple of months of rent. Houses are maintained. Not the flashiest area but whenever the tenants want anything we do it asap. What is a fair increase? We want to keep them below market rates as I think it would be too much to stomach. Is it better to raise it by, say, 7% this year and another 5% next year or do a bigger rise in one hit? If you’re a tenant, which would you prefer? We are 30% or so below market rate but I think market rates in London are insane. However our costs have massively risen too and they’re not about to go down.
