• Run every tap, then flush and run them againPressure on the third floor is where 1904 plumbing shows

• Check which way the bedrooms face at four in the afternoonSouth-west light is the reason for the asking price

• Find the meters — gas, water, powerIf they are not in the flat, someone else controls them
