One bucket for everything that recurs — letting and management fees, maintenance, service charge, insurance — as a share of the rent you collect. Ten per cent is a common working assumption; a leasehold flat with a service charge is usually higher.

Yield before finance and before tax. Mortgage interest, purchase costs and your own tax position are not included, and no rent or price is estimated for you.

Net yield4.1%After voids and operating costs, on the price paid.
Gross yield4.8%Headline annual rent on the price. Ignores every cost.
