we just managed to get ong to run all new lines and separate meters for our whole apartment complex at no cost to us. 

That’s fine down the line, but for your first property, I’d lean toward familiarity.2.

AirBNB is a platform.Personally I like a single, eye catching line.

I’m hoping to find more success in Phoenix, but as you stated, the old fashioned way may be my best bet.

My bet is you do not get sued.  

Don't be afraid to ask them why they don't want to apply.When I'm having pricing discussions with owners I work with, I always remind them: a month of vacancy costs your bottom line more than a unit filled with a rent reduction.

The second was in 2022 when I had 3 or 4 in line to be rehabbed and one became occupied by squatters who bothered the neighbors.

Do you have a price point you're targeting and are you looking for turn-key properties or something along the lines of a "fixer upper"?

Seems like the new on line marketing methods  Section 8 is the new shinny object..

You have used home equity lines of credit to purchase investment rentals and want to know the best way to pay down the HELOCs.Between the two properties you bought, after expenses, you have $250 a month positive cashflow to use.What I like to do is pay down some principal every month with my positive cashflow.I use my extra active income from real estate commissions helping other investors to pay down the principal even more which just frees up that credit for me to use again.I know I can refinance the HELOC debt before it changes to principal and interest as it is just interest only payments as yours are.One difference is the cashflow, I have greater positive cashflow and could make the principal and interest payment in the future with the extra cashflow I already enjoy.I always get HELOCs on my income properties as well after purchasing them to pull out as much of my downpayment as possible.
