Could this new equity interest be attached to a 1031 exchange, allowing me to defer the total value from the property and the equity if I sell it, and possibly defer again? 

I did not use an agent, I made signs with my number and attached them to the building.

Is it possible to 1031 into a business purchase if there is real estate attached? 

This could potentially implicate the buyer.Also, code enforcement liens placed on other properties held by the fund in the same county cross collate and can attach if you purchase.  

The book quotes a lot of the IRC, but just mentions the recommended closet dimension, no code attached to those dimensions.

Most recently I paid $2.75 per square foot for 12mm thick with attached foam underlayment pad at a damaged freight store.

Any offer you submit through your agent will need a pre qual letter attached with it.

But if you have your assets separated, then you only risk the LLC attached to the liability that initiated the lawsuit.You can actually still accomplish this by creating a single Series LLC, compared the the Traditional LLC.

Not only do you not know the quality of the work, but eventually they will embellish repairs that need to be done just to get money off their rent. 

Look for an attached garage with accessible water and sewer plumbing, with garage on same grade or below grade from the house, with adequate headroom if below grade.
