i could not afford the capital investment to buy a house, and i am not interested, it would only lock me down. my family once bought an apartment. we lived there for a few years. the mortgage payments were twice as high as the rent would have been. when we moved out we were told the place could not be sold. the family still has the place and it is probably still empty. lots of money wasted.

when you buy a house with the intent to sell it for a profit, then you are driving up housing costs. i'd say that's even worse than renting it out.
