Using a HELOC to purchase land for ground up construction cabin project

[Zachary Cain Humphrey]

I have about 60K in Heloc money I could use to purchase land lot in the Red River Gorge of Campton KY, pay that land off with the heloc, then use that paid off land to secure a construction loan from the bank or PM lender for a new ground up build. We currently have used our personal funds to purchase one lot already and have our first ground up construction going right now. But are wanting to move with pace! Any recommendations? Preferably the plan would be to pay the heloc off on the back end when we refi out of the construction loan or sell the property later once build is completed. I know the big thing would be to factor that full heloc payment into your carrying costs equation. 

Thank you all for any advice you may have!
