In terms of square feet, most of a property's façade is made up of walls. Consequently, they have the greatest impact and it's worth making sure that the finish on walls is as good as it can be. Buyers will be put off by crumbling mortar, cracks in the stucco, or huge fissures in cladding, because they know they might find some real nasties beneath and that these problems may cost a pretty penny to fix. If brickwork needs repointing, render needs repairing or replacing, or the façade needs painting,
I would always recommend that you do it before you put a property on the market.
