Where can I find a broker that can source out a construction loan for a spec home?

Or any loan that was made for the repairs and the note attached to the property. 

If there's competition for the property, you might need to provide a price first and renegotiate later, especially if you have a contingency for well and septic issues.Step 4: Fixing the SystemsAfter securing the property, we start the permitting process for well and septic repairs immediately.

In most cases your better off buying with "All Cash" and then you can use a "Delayed financing" program to get up to 80% cash back LTC loan to cost.

@Rich Solano, I wanted to provide one additional route you could look into adding on to what @Jon Taylor mentioned. 

Rates will be lower for a 2nd home loan, but as Michael stated you will have to acknowledge in the loan docs that you will not be renting out the property.

Seller often think "Where will I get the money to loan you?"

My plan is to use a first-time buyer's loan program, live in the property for a year, and then turn it into a rental property.

We recently moved a property into our LLC from a business partners personal loan.

Some hard money / private investors have minimal loan amount restrictions.
