Dear Monty: We have an offer on our house. There are several contingencies, one of which is a home inspection yet to be scheduled. When the buyers initially looked at the house, they asked if we ever had any condition issues. I told them we hadn’t. We had a leaking roof several years ago, but I didn’t mention it because we had it repaired. They got wind of it and are now backing out of the deal. I knew it was a little white lie at the time, but I didn’t think it was a big deal. What can I do to rekindle their interest?…
