For new builders, you need to visit the sales office with them on your first visit. 

I recently considered using a 12mm water resistant laminate (was on sale at $2/sqft) that had a real wood look and is click lock (floating) laid down. 

So, you'll find things like sales and listing history.

Purchase price: $186,000 Cash invested: $100,000 Sale price: $515,000 This house was in BAD shape, bank owned, and no bank would loan on it because the well and septic were shot.

Tenant left, and, again, with my Realtor and trusted contractor, made $5k in repairs and improvements to make it sale ready, taking total investment to about $158k.

(long story, not very interesting read) It's a balloon at sale or maturity of the first loan.Anyway, I plan on recording it in second position.

I know I could risk it and see if the bank acts on the "due on sale" clause, that is not the question. 

The profits would then get re-invested into the next home and continue the trend until I am able to able to build the next home with the profits that were made from previous sales.

Can I still approach a short sale with seller financing?

South Carolina being a lien theory state, one would normally have an attorney draft a mortgage (which creates a lien on the property and makes the full balance due upon sale) and promissory note (which outlines the payment terms, interest, etc).
