Frogman55 - I'm beggining to like you more and more.
Talking about people who don't OWN their houses, rising prices is a very, very bad thing for them. It also affects negatively all the businesses where the business owner is renting the space for his business. Just the other day, i was reading in the NYTimes that the number of libraries in New York is dwindling down, and the most impact is being seen on the highest-priced neighborhoods, like Upper East Manhattan. The business rent there is getting so absurd, the only kind of business that can thrive are those that generate pure or almost-pure profit, like most boutiques and high-couteur - shops made for the rich to expend their excess. Some kid in china weaves the cloth, they put a stamp in it, and suddenly it goes from costing 1$ to make, to be sold at 200$.
Bookstores don't generate a lot of profit. Bookstores thrive on constant influx of costumers. Most Bookstores nowadays also have cafés that serve some drinks and some food. Coincidence? No. It's there because it boosts their revenue a lot, and they need it badly. High prices determine the kind of business that can exist in a given area. If the prices are too high, than most business can't thrive there. There's also the side-effect of rising home prices: rising rent.
Tenants are subjected to yearly rent adjustments. Most of the time, the adjustments aren't too much of a worry. But in a rising-home-price situation, rent adjustments can, and will, make the tenants leave. It causes an exodus of non-house owners, simply because once you hit a certain threshold, the kind of person that would have the kind of money to pay that high a rent, has enough money to BUY and OWN his own house. Rising home prices are very, very bad for those who depend on renting a place to have a ceiling, and, while at first beneficial to landlords, rising home prices can also mean they lose their tenants and can't find new ones, which generates a financial impact in his life. He's forced to either continue to pay the expenses for the houses without it generating any profit, which further impacts his financial life, while HOPING that the price rise trend continues long enough for him to turn a profit even though he had to expend a lot of money to maintain that house until it grew enough in value to be worth selling.
High home prices also generate speculation. Some times, too much speculation. The New York Times had another interesting story on Upper East Manhattan, that began with a russian billionaire. Said billionaire paid a previously unheard-of sum of money for a place in Upper East Manhattan with a view to Central Park. Oh, yes, the place was immensely beautiful and very spacious, with all the luxuries you can imagine. Still, the amount he paid - some US$ 85.000.000,00 - led other brokers to steeply raise their prices on their homes in the same area. Guess what happened. Prices soared, clients vanished, and brokers where left sucking on their thumbs and asking, "what the hell? Why aren't people buying it? They have the money for it, goddamnit!". Well... That's why you don't raise the price on EVERY HOUSE in a neighborhood because one shmuck decided to grossly overpay for ONE house in that neighborhood. What followed was, of course, a sudden and sharp decline on pricing in the area, reaching up to 40% decrease from previous (over)estimated market levels...
