Its a scare tactic and she is trying to bully you into letting her get away with this BS.You need to screen WAY better and/or hir e PM for future tenants. 

Some of the materials we choose and asked him to pick up (such as flooring) he replaced with low quality materials, I assume to keep more of our money for himself. 

Buy a quality property, stay away from the hood, rehab it as if you would move in, take your time picking a tenant, you'll be find.

Don't invest in a market if you can't find a quality PM!

The scope of work, quality needed, location etc will determine the cost.

@Derick JenningsRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.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?

One bit of advice where you can be ahead of the curve is to write down your screening criteria for possible tenants and commit to following it.

Go to BUILD YOUR TEAM at the top of the screen and look for local investors or meetups in your area.

You'll get differing amounts and qualities of leads depending on the type of marketing, but also depending on who you're marketing to and where.

@Nick HulmeMaking improvements to your primary to make it high quality enough to rent above market rents, rent it.
