If the increase in equity should be satisfactory, that's an argument for just letting everyone live in the place for free. I mean, you're coming out ahead.

I know other landlords with multiple units. If they don't think something will be an income producing property, they won't buy.

My point is that you charge market price. Because that's how markets work.

Price to rent ratio varies very widely between different markets. If you don't want to buy in a market with a high price to rent ratio that's fine. There's simply no rule that guarantees a price to rent ratio such that rent covers all costs plus the full payment on a 30 year mortgage in all markets at all times.
