> me having an "oversupply" of money will So, if you were to buy a house you'd spend more for the next 5-10 years but because your payments are fixed, whereas rents will increase each year, there will be a crossover point where your mortgage+tax payments will eventually be quite low. So people who buy a house may pump more cash into the economy in the future. Plus theoretically, whoever sold you the house will be spending any extra cash they get from it (if they buy/rent in a lower cost of living area, or if the house was sold as part of estate that goes to a younger generation). But yes, in the short term you might be pumping the economy with more cash than you would if you bought a house, depending on your ongoing savings rate vs. spending rate.
