Need help on "how to think about" a possible sale

[Kenneth LaVoie]

So...the question I need a "boot in the rearend" on is this: I have a 7 unit I bought for 170K in 2011. Under contract for 350K today but appraisal came in at 310K. We're financing 15% of 350K purchase price. I haven't done any renegotiating yet but want to prepare myself. 

Assuming they'll want us to come down, what are some questions I can ask myself to help me decide how MUCH? I was fortunate enough to use another "free and clear" SFH as collateral so only had to put 10% down. So "All in" was $14,500.

PL each year was, starting in 2011

-18,000

-2,200

1,360

17,500

30,500

22,400

29,400

25,800

10,000

42,000 in 2020 to date (less maintenance, etc. due to covid, lower oil use and price)

Assuming things "average out" it will generate $25,000-$35,000 per year from here on out. (NOT inc. deduction for "self managing")

Ideas? Maybe seller finance a little more, also come down a bit, say 10K? Ask agent to take 2.5% vs. 3% "buyer's agent commission?"

OR...scrap the deal and leave it to my daughter with our other 4 buildings, haha!
