@Dennis Nemitz The Phoenix market is healthy, supply and demand are not way out of balance.

If your market is demanding, you can filter some out through questions that might not consider discrimination.... like why are you moving from your current resident, what is your total income/month, ... etc By starting the conversation, you will have a feeling who you want to let into your house.

I mean as far as comparing it to other parts of south philly where there is and has been high demand for. 

For instance, you may learn from a tenant that the building blows fuses easily in which case you probably want an electrician to see what's going on (old wiring not able to keep up with modern demands?)

There is too much supply (too many investment opportunities offered in the marketplace), and too little demand (too little investors investing in these deals).

@Mike Mercado Like the people here have said, there is a lot of demand.

So the effects of supply and demand come in.

Can the land lord file vandalism charges for two bags of trash in the kitchen, and scribbling on the wall, and demand $100 cash to be paid in 3 days, or tenant be evicted?

The irony to me, is that lower priced areas are have consistent demand and the upper end off shore markets are still depressed.

Then I would look towards filling your spot and refinancing some of the new found equity and use some of that cash flow as income towards your next house hack, preferably multifamilies in a high rental demand area.
