The way I would like to structure it is not only showing properties for sale, but i would like it advertising on Facebook, Twitter, etc.  

On occasion I need to be 1099'd and I've never had any issues with 1099s being issued in the firm's name and tax ID number.And @Sean Cole's strategy of an LLC taxed as an S-Corp can lead to some pretty advantageous tax treatments in the right situation.I imagine the most likely obstacle to this sort of setup isn't a legal prohibition but a brokerage that, for whatever reason, won't go along with the structure.

Do check the county property appraiser site to be sure their info. on structure/size matches to what's there.

I have my Architect as structural engineer on permitting the garage to livable space and fixing a detached garage to the lot.

Of course your current total loan amount and structure needs to be considered in this decision.Good luck!

Some people would be scared of that but I know the market and the structures of the houses and I can see how they withstand.

Things like fungus damage of the subfloor, support posts in the crawlspace in soil contact, hairline cracks, and (scariest to me) no foundation on a portion of the structure though majority is pier and block.  

The thing you want to be aware of is how the deal is structured with the owner, because they may want you to pay up after a certain amount of time and if your not ready bad things happen.Another way is using your IRA or Self Directed IRA.
