There is one IRS-approved method for building or improving that uses 1031 funds.Construction 1031 Rules and Process In a nutshell, it goes like this:You go under contract to purchase the replacement lot in OklahomaA 1031 company creates a brand new LLC to act as holding company (Exchange Accommodation Titleholder)You enter into an agreement with 1031 company outlining your plans in the construction exchange You assign the purchase contract for the lot to the new LLCYou arrange financing for the LLC to purchase the lot (this loan can be from you, a third-party lender, or your 1031 sale proceeds)Loans to LLC is secured by Note and Deed of TrustLLC buys the lotNow the LLC can begin paying for improvements to construct the barn-condoDuring the building period, LLC rents back to you and makes you "Project Manager" to oversee the improvements.Once improvements are completed -- or at the end of your 180 days -- 1031 company assigns ownership of the LLC to you. 

I don’t particularly like this method as you will have to track two separate loans.

You cannot get conventional financing using this method.

For the record: "The monthly S&P CoreLogic Case-Shiller Home Price Indices use the “repeat sales method” of index calculation – an approach that is widely recognized as the premier methodology for indexing housing prices – which uses data on properties that have sold at least twice, in order to capture the true appreciated value of each specific sales unit.
