Rent in. Mortgage out. Job done?
Not quite. π
Take a typical East London one-bed flat:
π· Rent: Β£19,800 a year
π Mortgage interest, service charge, maintenance, insurance, agent fees and voids all come out first
π§Ύ Then Section 24 takes its share of the tax
Whatβs left? Just Β£914 a year on Β£115,000 of cash invested. Thatβs under 1%, not the 5% the headline yield suggests.
Most landlords never work out their true cash return. They track the rent, guess the costs, and assume capital growth will cover the rest.

β
