In response to your original question, closing agents should handle private loans just like a bank loan. 

Quote from @Robby Sanchez: can you refinance at the end of an interest only loan into another interest only loan? 

I bought a 3/2.00 home in Tampa, FL in April 2022 for $245k at a 4.75% interest rate, I still owe $210K on the loan, my RE agent thinks it could sell for $280k ($70k in equity).

Other than paying for an appraisal or BPO (and maybe a credit report), you should not pay a lender anything until your loan funds.

The DSCR loan would allow you to qualify based on the rent you are collecting and get up to 75% of the value (175 x 0.75 = 131.25k, minus 20k payoff and closing costs.You could get a line of credit or a bridge loan against it to borrow money, but it would be higher interest.

Are you needing a long term or bridge loan?

I am relocating to Southern Florida around March/April to serve as a recruiter at the South Dade Recruiting Station in Miami.I am planning to purchase my first property and aim to take advantage of the VA Loan and Basic Allowance for Housing (BAH) benefits to make this possible.

Right now, the best offers around me are for some 1.3-4 million, that only generated around 100k per year gross, so there would be a high chance of not cash flowing, and paying money, especially with a commercial loan (these buildings have more than 4 units).I was thinking that although the rental itself does not generate money, I would be able to deduct the mortgage interest, and depreciation from my personal w2 income and would be net positive.

So, I've closed hundreds of loans for people. 

@Zach Howard there are a few loan types here in the states for foreign nationals, some that require personal income verification and others that do not.
