My goal is to save up 80k cash and get into a deal that I can cover 100% with my own cash. 

It sounds like you need to do a cash out refinance on your investment properties.

In the long run you will save a lot of money while at the same time earning way more money.

Offer hard cash for everything they lose every month they lose it, that MIGHt protect you.

If these have the 2 position's to make up the puchase price, how can I use BiggerPocket's in finding the 2 lender's to satisfy each position to purchase the cash flowing property?

Your best bet is to borrower the downpayment (although, if your property doesn't debt service, you won't cash flow)

Cash flow per unit, how much is left on mortgage per unit, etc.

I would highly recommend, if you househack a multifamily, you should target 3-4 unit properties instead since those will cash flow once you leave.

We did not fund the last few million of the raise, so we are allowing the final slots to come in at up to 20% APR, fixed annual simple deferred return (deferred means you get all of your interest earnings at the end when we repay your principal – and that happens when we finish building and then sell the apartment complex).This asset is our safest MF asset, in my opinion, BECAUSE the project is backed not just by our equity in the apartments – but by our equity in the entire 54-acre land development.

Your PM was using something called pay near me/retail payments for collecting cash payments from tenants at the CVS.
