Getting funding for a half built home (flip)

[Gabriel Ramos]

I'm looking at a property in Oakland that was a was a near new construction. I say near  because several of the walls of the original building are still standing. The foundation is already in and most of the framing looks to be complete as well . this project would work really well for me because I'm in the residential remodeling business. I also have my own Crew so my building cost would be less than a typical investor would need to put in.
I would love some advice on how to fund this purchase. I have a coupled hundred thousand in working capital for my business which I can use for the build out but I would still need money for the purchase and another 300K to complete the reno. I'm will to look into hard money or even a partnership. I just got this today so my numbers are rough at his point but even with hard money and 12 month hold I see the potential for a 30% ROI.
Thanks in advance
