You are the beginning of the process of that decrepit house become a family's home again.As far as the gun goes-get a concealed carry permit and bring your own. 

However, like an RV a Park Model cannot be permitted as an "Additional Dwelling Unit" (ADU) aka "Granny Flat" and therefore is not allowed to be permitted or permanently installed on a real estate lot or parcel.Unlike their big brother the HUD Manufactured Home, Park Models are built under the ANSI code and cannot exceed 400 square feet of living space.

When I asked the lady in permits about him, she immediately knew who he was.

Leave one or two walls so it won't be a full new build but classify as remodel, it will skip a lot of permit work.

What is hard to find in rural / small markets are licensed electricians and plumbers when a permit is needed.  

In case you missed we are having a Atlanta: BP Networking Open House - Multi-Family Investing scheduled on Dec 05, 2015 from 9:30 - 12:00 pmIf your schedule permits come network with fellow investors here in Atlanta. 

We'll have a soda fountain, mechanical bull (yep, I'm serious), karaoke room, pool table, 500 sq ft skylight (if permit passes) and a hip and cool atmosphere opened up to my local real estate investor friends.  

The general is as follows:-have a builder that owns a property with a partner on a British Overseas Territory-vacation destination with soon-to-increase traffic via increase in major cruise line stops-they have additional property to offer (at least a portion of) as collateral-plan to build 13 condominium units to sell (already permitted); builder claims to be able to construct in 5 months-looking for an individual or organization interesting in financing the project as a Joint VentureNeed an appropriate staging ground (perhaps within this site?)

Tread very lightly.Next go down to the building department and pull up a history of any/all permits relating to the property.

Also, get an invoice for everything and have copies of all the work done (permits etc) on your home.
