Your personal residence is more than just an investment, it is your home. If I were to assume that both homes equally met your needs regarding size, layout, storage, deferred maintenance, if any, parcel size, mechanicals etc, then we could talk apples for apples. In that instance, I would probably have to mention Beachwood's strong tax base, community amenities, and highly rated school system. No one has a crystal ball. People can prepare elaborate ptojections, but all they are are projections. Lastly, please don't dismiss the potential emotional impact of moving into your parents' home. If you feel warm and fuzzy about it, great. Otherwise, maybe best to sell.
