The state is already massively overcrowded in the cities and you don't alleviate the housing shortage by converting some SFR's to multi family.

I have run into situations where sellers are ready to sell but they don’t want to give up the cashflow, or don’t want to pay a significant chunk of taxes in the year they sell, these concerns can be alleviated with seller financing  

It is like walking down the street and a 6 foot 5 inch muscle bound biker bumps into you and it is clearly his fault and it is followed by you apologizing to him, Right or wrong.... a fight would not end well.

@Jordan Workman nice work exercising your "deal analyzing muscle" - practice makes perfect, and being able to quickly vet the financials on these deals is an essential skill for any investor. 

even if you don't use them afterwards it has been theorized that writing creates muscle memory and helps you to retain information better!!  

How long it takes you to develop the necessary skill depends on a) where you started, b) how much you "practice" and c) your personality type.It has taken me, as a Real Estate Professional, a great deal of time to develop the negotiating muscles necessary to confidently assure my buyer clients that we have the best deal possible.  

When you communicate your key with confidence, their fears will be alleviated and they will feel more comfortable going through with what you are offering.On the other hand, if you sound unsure of your offer, the seller will not call back or sign the deal.

I'm a cash buyer and can move quickly to alleviate your clients foreclosure concerns by purchasing their house in a win-win situation.

I also used some muscle car stamps instead of the regular American flag ones to hopefully make it seem more "friendly".

Also, is you do right by each party it can lead to a referral or more business down the line.At the end of the day @Josue Velney hit the nail on the head, you are a problem solver and your focus should be to alleviate the problem that the seller has with this property.
