Do you have to remove the sign to build?

I am also paying for transfer of taxes up to $3500 since I am having my friend removed. 

@Scott Kunz I found it to be a waste of time.

I just don’t want to join because people just want money because I don’t have the money to waste, just trying to get started.

This includes $65 of PMI that I can probably remove if I got it appraised. 

I was going to start looking around a bit but do not want to waste time if there is nothing like this out there.

It's far too easy for me to stray from the plan and end up wasting a ton of time chasing leads.

In NJ, I believe there are licensed contractors for mold removal with only 2 approved procedures as I recall. 

( they have about 90 days to either sale or remove home to dirt only)  This can be very expensive also.My very first flip was a "fire damaged home".   

Yes, but you need to narrow it down a lot to have a coherent answer.You will have to look at (I'd recommend in this order) the city codes (if it's inside a city, many cities above 50-100k population aren't friendly to development of these), the county codes (most counties are friendly to these, but you will probably have significant issues in major counties like Bexar, Travis, Dallas, Denton, Tarrant, Harris, etc), then you will have to comply with the state-level (TCEQ and others) on the water supply and waste water treatment systems.To put it in perspective again, in say Dallas or Austin, you will likely have prohibitions or very significant hurdles on developing RV or tiny home properties even on unincorporated, "unrestricted," AG-zoned properties at both the city/municipal level and county level.
