It can’t even be a factor for checking into her credit further (sort of the fruit of the poisonous tree doctrine concept).

These deals are extremely few and far between, the seller usually isn't in a position to pay commission on the sale, and the juice is simply not worth the squeeze for a successful real estate agent who needs to make a living. 

But, there's no way I'm growing my own banana tree and harvesting the fruit.

This is in Broward County, where it seems that all our deals are made by negotiation and not much low hanging fruit here.   

What the seller appears to be doing is juicing the numbers for over market value to provide seller financing.With interest only there is no paydown of the note.

2) What are the low hanging fruit? 

I feel like I need to make a solid run in the next 5-7 years and then move to a more passive role where i am able to enjoy the fruits of my labor with less of a time commitment on a regular basis. 

I'm sure the hours spent on networking and lunch breaks is bearing fruits for your right now :)

So if when looking at numbers with a hefty vacancy factor, and a decent reserve fund,  and the "juice is still worth the squeeze" - Then I say go for it. 

These will burn through a 20% discount in a heartbeat.Perhaps, in a sub $200K price range a 20% discount would get a rental investor juiced up a bit.
