Rooms range from £65 per week for the smallest, £80 per week for the medium size to £100 per week for the largest. Prices are all inclusive of utilities, internet and, in a house full of hygienically challenged boys, a weekly cleaner. Therefore, in a 5 room house of 1 small, 3 medium and 1 large rooms you can expect £410 per week or £21,320 per year. Utilities amount to £4,200 per year, leaving £17,120. The average house cost £174,000 in 2007 which means just under a 10% yield without taking voids and non payments into account. Hard work, but a pretty good return in the current climate (unless you were left a portfolio of properties by a great grandfather without any mortgages!). Deposit is £150.
