In the US anyways you have favorable tax treatments for interest and property taxes, but rent (of private properties like houses) tends to exceed principle + interest + taxes in many areas. I find that to be fairly weird, because you've essentially got a very low out of pocket expense at that point (or even nearly net positive) in raw money exchanged, yet principle is recoverable on sale and tax deductions offset a portion of property taxes. Basically if buying a house and renting it out immediately turns a profit, that's a renter-saturated market, and it seems best to be on the non-saturated side of the market
