We are in this situation right now in Temecula, except we’re the renters. I don’t think you have a whole lot to be concerned with, considering they were owners and are buying a new house – i.e., on the surface it sounds like they’re responsible enough. In our case, we sold to a pair of Chinese retirees, all cash. We needed to rent for 45 days until our new construction is complete, and worked out all the terms in the contract (no deposit, 45 days rent in advance, with an option for more time at market rate if needed). They aren’t nitpicking us about anything (haven’t even heard from them or their pm since closing, in fact), which we really appreciate. Funny thing is, because we still have a bit of an attachment to the place, I’m the one worried about them taking care of it. “They do know they need to hire a gardener asap, right?” We’re taking the same good care of it we always have, and we’ll leave it spotless when we go.
