Honestly, if you don’t trust them or like the way they are communicating I’d interview a couple more PM’s in the area.

Quote from @Casey Nelson: Send them my way please always like looking for stuff on market and of course off market.I have a private money lender in my back pocket  just trying to get started.I guess I can’t post my email on here  No worries, we'll continue communication in DM. 

Investigate conventional finance, FHA loans, and other programs that can be in line with your objectives.Through networking, word-of-mouth, or direct communication with property owners, take into consideration investigating off-market options.

Very slow to communicate, having to send multiple emails and voicemails without any response.

That being said, like most things with being a landlord, if you are a decent person treat your tenants like people, remain communicative and respectful, make necessary repairs, it is highly unlikely you will ever get sued or anyone will ever question if you did everything by the book.  

They have consistently failed to communicate essential information to the sellers and their attorneys. 

There is no secure, streamlined way to communicate with all parties.

I should lay this out right off the bat - I've only been with Evolve a few months and really have had no issues with them so far, I just want a little more control over my listing/communications and don't see much value in the automated messaging that they do.

The industry is seemingly caught very off guard by the massive failure of NAR to communicate the potential outcomes and timeline of the agreement to its members. 

You realize all your communication you are liable for?
