Setting up a refinance with an escrow would be fine, but if your ARV is only 75k, then most groups would do 70% of ARV, which after your 7500 payoff and closing costs, puts you with an escrow around that 40k mark. 

Get specific and refine your investor avatar.

If you can, I would wait another 12 months to refinance.

Hopefully you didn’t just do the cash out refinance.

For example, if in your 3, interest rates drop to 3%, could I refinance then into a traditional loan?

As a buyer, you're less likely to get the terms you want, you may pay more for a house than it's actual value, and you may lose some of the offers that would have won.Buy now, refinance later (if that makes sense for you).

I never imagined I would sell or refinance the 2 best ones because I have 2.65% mortgages on them and they cash flow well, but want to make sure my equity is working up to it's ability for me. 

The mortgage holders may call you to pay off the mortgage (refinance) if the deed is moved over to a LLC. 

That said, I'm unfamiliar with the market and would love to meet with other investors who are finding some success (and mishaps) to help refine my game plan.If there are any REI meets ups please let me know!

If you are looking to hold long-term, I would bring on a private lender for the rehab and then refinance and pay them off.
