I bought my house about a year ago, since then it's gone up in value by about 30% (based on comps of nearby home sales) A neighbor sold his house recently, he said he had a half dozen offers in a week, 3 were over his asking price, 2 were all-cash with no contingencies. I don't know how this market can be sustainable or how the average buyer can compete if they need a loan.
