BRRRR concept and paying back a hard money, private money

[Joe Prew]

3-part question:

1). Is the idea to pay back the hard money with the money we get back from the Refinance part of the deal? If not, how would we pay them back?

2). Can we refinance right away, is it generally 1 or two years out?

3). Lastly, what tools (documents/paperwork) should I use to have my strategy and numbers outlined so it looks and sounds professional when I'm sitting I'm pitching my ask for 80K to 100K.
