If you have a signed 1-year lease, you may be able to make him honor the terms, and there are usually tenant hotlines through your local government that can answer those questions for you.  

The only time you can sell a house and not have the government take a share is with the sale pf a primary residence I sell the house then leaveage the money to get  investment properties Id purchase a new primary residence with a 50 % down and have a line of credit not a mortgage so as not to tie up all my funds..........but that is just my opinion

You will need to set up the proper structure and comfy with SEC and state securities regulations of course but thats easily handled by an SEC attorney.The one thing you do not want to do is purchase a property under your company and do a JV or profit split with an investor.

One of the hurdles in buying these properties (and the reason you can get a good deal on them) is that oftentimes they have deficiencies that make them ineligible for government financing (FHA, VA, USDA) and make it much more difficult to obtain conventional financing. 

The complication is that any mortgage would have to satisfy the laws, rules, and regulations of two different states.

If the governing authority in your jurisdiction would consider allowing you to build more units on that lot this could be a winner even if you flipped this once the approvals are in place.I just completed 165 room Marriott and the city was very cooperative.

California has regulations about this.

Does the Villages allow STR in their regulations?

Just as important as the Act itself is learning how the Residential Tenancies Tribunal (RTT) {formerly the Office of the Rentalsman} applies the law and the regulations which accompany the law.  

That being said, it will take me quite some time to save up the amount of money the government is sending my way.
