And for an OOS, I always advise to keep things simple at start, don't get greedy, go for quality and consistency, then work on maximizing monetization later. 

I had a tenant force me to pay for some dumb azz air quality test where she claimed my air was bad and making her sick.

@Ezra Avery you might want to read below to understand Classes of Property/Tenants.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

I'm curious about the size and quality of a house you could build for $375k. 

The biggest thing to me is buying in quality areas that will increase in value over time.

Are their listings detailed with good-quality photos?

An eviction will make it challenging for her ever to find a quality rental in low vacancy areas.
