Once non-paying tenants have been evicted, decent rent insurance should also pay at least some money while you advertise for replacements. Letsure, for example, will pay 75 per cent of the rent for up to two months till the property is re-let, while Endsleigh will pay 50 per cent for up to three months. The problems you would otherwise face paying the bills during void periods are just one reason why experts like the Association of Residential Lettings Agents (www.arla.co.uk) say single property buy-to-let investors are most in need of rental protection. Landlords with many properties may be able to subsidise one empty property with the money coming in from their others. New investors without this opportunity may risk going into arrears if they donít have decent insurance.
