Rental Yield Calculator

As a rough rule of thumb, many investors look for a gross yield above 5%, though what counts as "good" depends heavily on the area, property type and your own goals — a lower-yielding asset in a strong capital-growth street can beat a high-yield one on total return over ten years.

Conventional things like insurance, maintenance and void periods, plus letting fees if you use an agent, compliance costs (certificates and their renewal) and any service charge or ground rent if the property is a leasehold flat.

That's a question for a mortgage adviser rather than a rule of thumb — the answer depends on the rates available to you, your lender's attitude to portfolios, and the tax treatment of your current holdings. Our advisors handle limited-company and portfolio cases.
