Proof of Funds Letter for Flips?

[Joshua McCarthy]

Hey all, 

I'm currently looking at a potential flip in my hometown of Batavia, NY and have come to an agreed upon price. The seller is asking for POF with the written offer. My plan was to use private funding or HML but I'm open to a JV with a partner that can finance the project.

My question is, if i don't have the property under contract how do i go about showing the deal to a potential partner that i don't know and trust? Couldn't they just cut me out at that point? 

If i go the HML route, is it as simple as giving them the address and numbers and they provide me with a POF letter?

I have a residential construction background but this is my first time securing financing for a flip. Any advice/ insight/ tips would be greatly appreciated!

Thanks!
