I'm the VP of a roofing company in South Florida and work with a few good PM companies on a regular basis, a lot of bad ones too.There are good and bad PMs in each of those companies. 

I'm still in the process of growing my portfolio, but have heard others 1031 all their smaller properties into a larger building and have a property management company manage, OR, set up a seller financing deal with another buyer that gives you the cash flow you desire. 

@Christopher Smith there are many...but in my opinion really only three companies out there that offer the ability to 721 into a large and diversified REIT that i'd feel comfortable with. 

Ask your mortgage company.

I am currently living out of state so I have hired a property management company to handle this task, however, my home is still sitting vacant with very few prospective tenants.

I was new to the SFR investment world, and it was important to me to work with company with good reputation that can act quickly.

@Kana Watanabe HI Kana,  I work with a company who specializes in ADU's.  

Companies typically last only ten years on average.

So this program is between the property mgmt company and us, mostly. 

Quote from @Trent Reeve: well, a company would have to 50 states and build in integration functionality for 50 different systems.
