That is a LOT of repairing, even if you buy all the houses in every town. If only you set up the houses to auto repair, like the homes you buy for yourself. That would be a good idea. Imagine taking time out from actually doing the quests and storyline to hurry home and repair everyone's houses. LOL "Hold on, bad guy, I have to run back home and repair some homes and stuff. Can we duke it out in a few hours? Thanks, bad guy. Back in a mo."
