Currently selling house. Put up for sale for £295000 just before lockdown. When housing market opened again, we accepted an offer of £278500 from a couple in rented accommodation with a 25% deposit and a mortgage in principal already agreed. While waiting for survey, the flat roof died so we have had to spend £3000 replacing it. Due to flat roof leak, wallpaper at rear of lounge and a small section in the kitchen is ruined. There is a section of the wall which is damp and will take time to dry out. We have had to remove the wallpaper in the section affected.
As we have added value to property by replacing 11 year old flat roof (cost £3000) and also discounted asking price by £16500, is it reasonable to ask our buyers to sort out redecoration after they acquire the house?
