Good luck, if it can really rent for 2k per room, thats 40k+ a month which crazy cash flow on 1M loan. 

Is cash flow the main objective?

Cash flow on day one!

I have some cash coming my way soon and trying to determine if I should use some of the cash to recast some of my mortgages to increase cash flow or not.  

Why would I invest in deals with a 4-6% ROI that will cash flow a couple hundred a month (if I’m lucky) and go through the trouble/risk of property ownership when I can get similar returns from other completely passive investments with practically 0 risk?

I can definitely tell you there's still a lot of positive cash flowing and 1% rule deals and you get amazing appreciation.

If you want the long-term play for cash flow, then keep it, but likely, at that price point, it sounds like a flip to me.

We typically buy off market, but I know the networking is one of the best ways to access off market deal flow through brokers. 

I reap the cash flows on those.

What can we realistically expect from a builder in terms of closing cost assistance and/or rate buy-down I would never buy a new build at full price and count on zero cash flow. there was a guy who bought one and it doesn't cash flow and he's counting on appreciation. you should at least look at multifamily and in addition look at building your own.
