Unique Hard Money Lending question

[Mark Vannasdall]

I am building a home in Florida. It will be a second home but also part time rental.  it wil cost 500K but homes exactly like it or some with  less upgrades are selling for 650- 700K quickly     Should i get a regular mortgage and then do refinance cash out or is there a way of using hard money/ or other financing  and rolling that into a new loan after close.   Has anyone encountered this and have advice.  Thanks
