My initial thought was looking into the best approach (if any) with this lender to get one of these two specs at a discount which would get one of them off their books.

I’ve periodically had tenants at the Multis offer to “help with the landscaping” in exchange for a discount on their rent.

This was a major rehab ($160K) and I've already discounted the price $40K from ask.

Have you looked into working with any local businesses to provide discounts for guests and piggyback off their customer base?

She sold it to us at a significant discount due to years of deferred maintenance—broken doors, heaps of junk, and more.

They might give you a discount to add it.

They tend to start doing "fire sales" which means dropping prices which causes all of the homes they closed on the previous 12 months or more to lose value based on new discounted comparable sales.That is why you see builder always offering crazy "Builder credits" which in most cases are "ghost" funds. 

(Both that you know about now and that you are told about form your buyer’s inspections.)Most buyers are going to discount their offer by double what they think it will cost to repair what they can see plus the “mystery repairs” you’re hiding with your as-is sale so you will make much less on the sale. 

Reasonable rates and options for a discount if rented more than (x) days.Make the home extra attractive buy some things that make the home stand out like games for both the parents and the kids.

Option 2: I found a house that the asking price is 930k , but I’m sure I can get a discount on it because it needs a lot of work , it doesn’t qualify for traditional financing , so I would need to take a hard money loan , it needs about 150k worth of work , the plan would be to offer the full 930k asking price but ask for a 6% seller concession , I calculated 20% down payment and 7% closing cost , so total after seller concessions comes out to 21% down payment which is $195,300 .
