Also interested. We have a large home i would love to swap, but would likely need to help someone manage a few quirks (once every few years, basement could flood, electrical has both fuses and a traditional switch box, etc).
How do you manage a possible minor issue or accident. Is it not viable with a larger, older home?
We live in a desirable SF region, so likely the demand would be there, but is it really sensible to loan a stranger a $1-2M asset? Does one throw in access to a few cars?
