I'm 24, currently have about $200k saved up, and have talked with a mortgage lender but not finalized getting pre-approved. 

For the previous 2 homes I own, I had my parents cosign the loan and that's how I got approval for each of loans, 1st primary residence in 2021 and 2nd in 2024.

With only a $50 or $100 origination fee, and "essentially" not losing any money to an interest rate, TSP loans are probably one of your cheaper loan options out there.I just took out a 40+k loan from my TSP to invest in other ventures and it was a very simple and straightforward process.

Or do the lenders require that I establish primary residence first, before getting an fha or a fannie mae loan for a primary? 

The deposit is common in commercial loans.

The single payment will cover both the original loan amount and the additional cash-out amount.HELOC might be better if you need intermittent access to funds, while a cash-out refinance could be more suitable for a one-time need with a clear purpose.

Rest assured that you don't need to bring all cash to the table on a fix and flip and we can assist you in closing the loan.

I understand that residential rental properties can provide positive incentives through loan paydown, tax incentives, cash flow, and appreciation.
