I converted a house into 3 flats a while ago, and I am thinking of selling the flats on long (99 year) leases. It is normal practice to charge the leaseholders a ground rent of a couple of hundred pounds a year.

My question is: are there any rules about how much I can charge, or how the rent will increase in future years? I appreciate that a higher ground rent would (or should) be reflected in a lower sale price, but are there any actual laws controlling it?

For example, how about I charge £1000 per year and make the rent go up each year with inflation.
Interesting ST. I am sure you would not have batted an eyelid if the rent had been £100 instead of £50 when you were buying a (presumably) £100,000+ on a flat. It does make we wonder why the builder did not do that.

As you say, multiple small incomes add up and if the builder had done e.g. 100 flats in that development, the difference between 50 and 100 would be a nice little bonus for them at Christmas! Or more practically, pay for the collection costs which I am sure is a pain when you have to go after multiple little amounts like that.
