With homes, most property characteristics that are attractive to some buyers hold the potential to turn others off. Swimming pools promise exercise and recreation to some, but loom as a dangerous nuisance and maintenance problem to others. Some buyers think gated communities are tony and prestigious, while others find them exclusive and bourgeois. Urban/suburban, condo/single-family home -- heck, I've even had clients who didn't want to live in our town's best school district because they don't want kids walking on their lawns!
But there's one home characteristic in my world that lately seems to be unanimously sought after by buyers of all sorts: walkability.
