Hard Money, Bank, Private Financing ?

[Roy Means]

Ive decided I want to create financial freedom through real estate investing. And the BRRRR method (Multi-unit) is the way I want to go with flips on the side.

Im about a month in on learning and self educating, I have a few quick questions about the financing/Money part of the deal.

With Hard money lending do you pay monthly payments on the interest of the loan as soon as you close the deal? For example: 100k loan for the house, 8-14% Interest, Monthly payment 8-15,000

How would you be able to pay that monthly payment while in the process of rehabbing and putting tenants in place if your just starting out?

If the goal is to refinance and then pay off the Hard money loan. If you had a plan together and in place Would the lender wait 8-12 months before the first payment? Is that normal? Until Ive completed the Refinance to pay them back?

I do apologize for the long paragraph would love some feedback on this if possible,

Thank you all,
