Can anyone recommend good companies to root cause  and implement solution to fix this issue?

Now you have a problem because the new people are technically squatting. 

Some of them even walk off the job, even after they pull permits and are technically responsible for the work.  

2) If you do owner-occupied cashout refi for best rate, you technically have to live in the home for 12 months before renting it out. * Some responders here may suggest not worrying about that and renting it out anyways.

They may also be able to temporarily relocate your tenant to avoid any other issues.

I recently came across 1 acre asking for 314k in a very good residential and growing location, so the current owner has added 4 manufactured homes with 4 electrical meters, 4 septic tanks and only 1 water meter for all 4 homes, the homes are sitting on partial slab and partial pier & beam, he also added 2 storage sheds approx. 380sqft with the intention to make them ADUs they are still only the shell so I would have to get those ready to live in, so currently the 4 manufactured homes are being rented and bringing in 2800k a month, 3 of the homes are needing some TLC which could increment rents and possibly get me at 3600k a month, also being a 1ac lot this still leaves about 12,000sqft of raw land where you could build etc.So that is on the good side now the things I did not like so much, the lay out is poorly executed to where it makes it looked crammed up and not professional but it could be fixed.Another is that in reality there is only 4 livable units so that qualifies under a conventional loan but since they're are 6 units on the property the banks are wanting to take it as a commercial so we would have to move out the 2 storage sheds out in order to close as conventional.Another concern, technically you are only allowed to have one manufactured house or single wide in your property according to what I know but I know it could change according to zoning which I will investigate, so my question is has all this been accounted for and if so how can I verify it so it wont leave me in a bind further down the road, I currently asked my agent for the appraisal of the property to see if that might verify.Any recommendations?

Technically as the manager of the LLC you can open an accout with any financial institution though they don’t all cooperate when it’s an IRA owned LLC. 

And you're totally right, housing issues cut across political and other lines.

I left them recently like many others have in the last 5 months and even though our money was technically an investment and a limited partner contribution, they refused to give anyone their money back even after stating numerous times they would give people their money back if they choose to leave. 

Basically, these are lands that technically qualify as Sending sites, but that have issues such that nobody really wants to build there.
