Doing a property self-check won’t protect you but it might make you notice concerns you want to raise with the agent or your building or pest inspector. When you look around the property try to assess it with less emotion and check a few common issues:
See that windows and doors open easily. Inspect skirting boards, walls and ceilings for damp or mould. Look out for paint jobs that may have been used to cover up mould. Look out for sagging ceilings or buckling walls. Lift up carpets where possible to check for rotting or damp floorboards. Turn on all the taps and check for hot water and leaky taps. Flush the toilet to check for running cisterns. Look under sinks and give the plumbing a gentle shake to test sturdiness. Look out for rust and other damage to the pipes.
Review the hot water system for size and age, and check for damp in all wet areas. Try light switches and look at the fuse box to evaluate circuitry age and see if there is an Earth Leakage Safety Switch. Look at the general state of the roof, guttering and drainpipes. Inspect exterior walls for cracks and other defects.
