@Anthony Wick if you understand and follow your city/state laws, keep your properties in good repair, and are honest and communicative with your tenants, I truly believe you will avoid 99% of any lawsuits.

Send very short non accusatory communication stating just facts of area concerns.

Super good communication and low rates, solid underwriting process.

It also explained that they were having trouble communicating to the "tenant" and not hearing back from her, and the last thing they heard from people at the residence was when the boyfriend called asking if the property was for sale.

Sounds like there was a material lapse in communication with your lender, which led to information surfacing during underwriting that negatively impacted your deal. 

Don't get me wrong, every agent should absolutely provide great communication and service from day one.

@Adrienne Green @Chris John your written criteria can include a section on “demeanor and quality of communication/interaction during the application process” Perfectly legitimate to rank a group that is tough to deal with (kids or no) as less qualified. 

That is a communication between you and the sponsor.The K-1 will tell you what payments were made from the partnership/LLC to you which is mentioned on line 19.

Decent process, though their written rules (e.g. 30 day close or earnest money in 48 hrs) is not what actually happens each time (15 day close and about a week to EMD) and communication not the smoothest.

@Louis LordGo to school, learn how to read and write properly, work on your communication skills, make as many friends as possible, play a team sport, pass high school,  go to university, get a high paying job, save money for down payment, buy a duplex and live in one side and rent the other side.
