My agent is @Marcus Auerbach -- he's a seasoned investor and rehabber and understands the market very well.

I'm trying to find a long term financing option that would let us pay off the HELOC after the seasoning period.

I have found that to be the best way as you don't have to find a new vendor for each season. 

you are bringing cash (via wire or cashiers check) to closing for your 20% and the HELOC is secured against the other property, so who cares, unless you are doing secondary market, then they want that money "seasoned" but who buys in their personal name anyway. 

And due to the vapor barrier, (a huge plastic sheet) all the little (and not so little ) poopies stayed nice moist and fresh!

Get the LLC formed as soon as possible and get it seasoned. 

But like Joe said about a local group -- I'm trying to figure out when would be best to have a recurring day/time before I'd start it...but I think around Tax season is possible for us to do a Meet-n-greet.

About $650 average is what I'm seeing.During the busy months, I know the unit will rent out most nights, but I am worried about the off season in Vegas. 

If so, how are you avoiding any seasoning periods?

This is excellent idea, we did a few BRRRR with rate-term re-fi because of the seasoning limitation of cash out re-fi.
