The reputation of your properties is faltering, your being put at risk of state intervention, fines, and lawsuits. 

If you fail to follow the rules, you may open your personal assets to a lawsuit.

A follow up question, for those properties in your name, how did you manage to shelter yourself from any potential lawsuits? 

(Glass doors on the bath or shower are a lawsuit waiting to happen--IMO).

When they see this they you will most likely be named individually in the suit.To @John Mocker 's point, one of the reasons for the LLC is to keep your personal name out of lawsuits. 

So i think, best bet for us is to acquire a SFH with a mother in law suite/adu while we are still here in DFW. lastly , Can we still be qualified for another FHA if we decide to live in California and do another Duplex/ multifam?  

SFH-rent by the room, SFH-in-law suite that can be sourced as an STR or LTR, SFH-basement that can be converted into an additional unit, SFH with an ADU, & duplex (which seems to be your main priority) are all probably viable options in your market.

Non-disclosure is the biggest cause of real estate violations, fines and law suits, so you'll want to take care to disclose.I suggest the following:1.

However, it will not provide any asset protection if there is a lawsuit by a party outside of the partnership.

I believe this to be a rare find as I would actually consider it a mother-in-law suite but it is currently zoned as a single family residence while sharing a wall with the other unit.
