How can I negotiate to buy a house that didn't sell at $749k on the open market, subject to the existing mortgage with cash over, seller pay the broker fee and i buy "as is, where is"?

Purchase price: $300,000 Cash invested: $35,000 Multi-family property with two SFR homes on parcel.

. $16k entry cost plus closing costs.I have 20k saved in cash$83,000 pp 2bed 1bath 950sqft.

We’re under contract with them for an all cash deal but they keep missing closing dates.

But if your friend is not the actual buyer and signed the mortgage docs this could be impossible.sell in 2 weeks for cash. this can happen. as stated a above payoff the loan in cash now.If your friend is in title to the property they can file BK  which can be pretty devastating to someone long term but gives them time ..

Purchase price: $360,000 Cash invested: $80,000 This was initially a fix and flip deal that turned BRRRR.

Purchase price: $289,000 Cash invested: $25,000 4 2 bedroom units bringing in $800 for each unit.

Is it cash flow, is it appreciation, is it another strategy like a househack, etc.? 

Most will tell you to replace all to cash the big check.

In that environment buying in the hood becomes very tempting, but that little bit of cash flow comes with a huge cost in headaches, the probability of property damage (things like a charcoal grill in the living room) and long term you might just be treading water.Average net cash flow is probably around $200 per door after you have stabilized the property, so you need a few units before it amounts to something.
