There’s other ways to look at it. If someone is forced to sell, they likely took on too much leverage in the first place or didn’t save enough for a rainy day. Those decisions aren’t your fault, and by buying when prices are low, you are in effect giving them the liquidity they need which is a good thing.

Also, you never have to deprive someone of their housing if they are unable to pay. You can work out payment plans and all sorts of compromises to get through tough times and tenants will generally appreciate that flexibility.

The point remains - real estate is more stable for side income than a bar!
