It would be far simpler to put the $500,000 in a bank account owned by the LLC and you immediately own a fixed percent.

Never built in Houston before so take my feedback with a grain of salt but I'd put money on it being impossible to build a duplex from scratch for $125 a foot (including everything from drawings, engineering, permit fees, general conditions, labor, material, landscaping).Out here in AZ the builder cost is going to be $200 a foot at best, but add 20% on top of that for the client cost.

Brian, MTR's can be very strong in Greensboro.

You are 18, you shouldn't be ready to buy a property yet.

As you can never truly be protected other than making sure it's in the contract with your GC who is doing the project.  

It’s relatively close to Houston and has strong demand due to Texas A&M, events, and business travel, making it a flexible market for STR and mid-term rentals.If you’re open to exploring other high-performing areas, I’d be happy to share insights and data with you.

It will be a great future epsiode of American Greed.  

TN markets are still pretty free market so even if you do get cancelled there will be alternatives.

Any insight on how strictly that will be enforced?

I’d be happy moving forward if they are willing to take that $10K off, and be back at my original offer price.
