Once refinanced we would want to establish a revolving line of credit based on the equity. 

You should be able to get a revolving line of credit for your LLC that is secured by real estate that you own. 

The idea is to buy wholesale with a hard money loan that is 65% - 70% LTV (includes acquisition money as well as rehab money), fix it up and get a renter in it, then refinance to a 30 year fixed rate mortgage with a bank.Factors I know I need to accommodate for:- HML points up front- HML interest only payments (monthly)- Utilities- Insurance- Prorated property taxes (for the period before escrow is set up on the 30 year loan)- Loan origination fees (if these are not rolled into the loan)I have a near perfect credit score and zero debt, save for the revolving credit on my card, but that is paid in full every two weeks.My questions:1) How much LTV could I reasonably refinance out to?

You didn't say what platform, but if he does politically oriented YouTube, you could open yourself up to discrimination charges, or, if he does sexually oriented camming, you could be accused of sexual harassment.

Cash out refi means locking in the rate and making payments now while a heloc has variable interest rate as revolving credit which you can draw on as needed.

I've tried out one local REIA so far (and will try out the other too), but from looking at all the calendars, each meeting revolves around an "expert" trying to sell you something.

Otherwise, your rental is likely to have a revolving door.

I just got over $50k revolving credit setup and because it's business credit, I can max that out and it won't affect my personal credit score.

@cam@Cameron Harris There is a saying that I found that work for me, "The harder I work, the luckier I get."  

When sold I will buy a duplex and pay off any revolving debt.
