Instead of just traditional homes and condos, I want to venture into the unique world of Airstreams, Tiny Homes, Shipping Containers, Treehouses. 

Related to that last point and true whether you use one or more QB files, I create a unique category for each note.Because I have ZERO creativity, I use the address of the collateral securing the address as the category.  

I am in a fairly unique situation, and would love some advice on a first real estate purchase. 

Putting money into unique properties is also more risky.

*An RIA must be licensed with the State Securities Division, or in the case of California the Department of Business Oversight, which is in the state where your home office is located.

The market here is quite unique compared to the rest of the nation, and even to the rest of California for that matter. 

When first starting out do not do anything unique or different than what is average.

Once I am giving a Price Notice, and make the payment to the Alabama Department of Revenue Property Tax Division and received my Tax Deed for some property, more specifically a vacant lot in a now built up subdivision, can I sell to an investor or another individual whom wishes to build their own home on the lot.

You should start with a general idea of price point and strategy, which should get you narrowed down a bit, then you'll want to look at job and population growth (City-Data.com) and get a feel for each of the markets, once you have selected a market you can go a bit deeper into sub-markets and unique details of the market as a whole.

I'm not personally familiar with the ones on BP, but google the "Division of Real Estate Contracts and Forms" from DORA at colorado.gov.
