The comparison counts only the costs of owning you never get back: interest, running costs and what the deposit and purchase costs could earn elsewhere. Loan repayments build equity, so they are left out. So is any rise in the home's value, because nobody knows it in advance. Rents here are asking rents with charges included, from the ANIL rent map, so they run a little above what tenants pay in rent alone, and the yield reads a little high.
