I’m having issues with people being able to fill out applications on Zillow.

@Andrew Syrios technically, it forbids paying or receiving interest.

I have been renting my townhome up in Issaquah, WA for the last 10 years with no issues.

@Farzan SetayeshYou do technically have the ability to take them to small claims court if you wish.

We have had some issues with getting insurance for the Florida properties in the LLC and also related issue with the Mortgage (which is in our name).When our lawyer requested EINs for the LLCs we were informed by the IRS that we need to file a 1065 for each of the LLCs.Our structure is that the LLCs are owned by the two Trusts (50%) in each of our names.

In conducting a background check, I learn the applicant's current neighbors hate him, he's on a first name basis with the local police or he has a variety of other social/criminal issues chasing him.4.

Not an eligibility issue so much as who is able to take it on.  

Your property sounds to be more unique, therefor likely making it challenging to find acceptable comps. if the property is common for the area, it's likely this could be a non-issue with the right lender. 

Credit score shouldn't be an issue.

This may be a case where you are trying to force the issue by wanting to complete a flip transaction where your market is telling you its not the right time.
