Unless you are actively trying to sell your house, or your neighbors who have exactly the same tract house as you do are trying to sell, how do you know its price is going down ?
UH, excuse me. Knock knock. Hello? Anybody home? Sales don't make an economy. Production makes an economy. What are we going to do when everything we buy is made in China? Start exporting lap dances?
The average selling price for homes in a particular market is measured and reported widely, and it is not too much of a stretch to infer that one's specific home price is going down or up at any given time, this despite the ignorance of others on this forum.
In much the same way, the 'stock market' in general terms, or a specific market sector, is measured and reported as being 'up' or 'down', while an individual stock can of course vary.
But the way to bet is stock market up and house price down, at least for the moment.
Houses just like mine are selling for double what I paid just three and a half years ago.
