If you can't treat this like a business and get rid of bad renters, then I recommend you hire someone to do it for you. 

@Jessica Carcamo I would recommend going to meetups and meeting investors and others doing what you want to do and offer to bring in some capital and find the deal and partner with a seasoned investor on your first few. 

Anyone have a good recommendation for a contractor or handyman in Spokane, WA?

Are there any other books you recommend?

This is what I recommend for you:1.

Also if this is a good strategy do DSTs offer this type of investment and if so any recommendations. 

My brokerage hasn’t made it a requirement yet but has highly recommended it and the experienced agents are mostly doing it, especially the females.

My recommendation is to get a vendor to access and provide a written report, go from there based on findings.

The one tactic I'd recommend for those who can afford it, is putting down more equity (30-40%). 2.
