But with the widow's interest deeded to you, getting clear title should be easier. 

The owner is a widow and her husband was the one that really ran the operation before.Everything else you mentioned makes sense. 

[James 1:27 ESV] “Religion that is pure and undefiled before God, the Father, is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world.”

Our landlord’s estate was still being settled and we said please keep us in mind. 7 months later we purchased a new home. 2 weeks later our realtor told us his widow is liquidating the estate and she’d be selling the 4 plex.

They will say you took advantage of a grieving widow for your own personal financial gain.

And to be honest I feel terrible about it because 95% of the negative feedback is coming from widows who just lost their partner and have no desire to sell their house. 

Be mindful that they have lost a relative or a friend so you want to be courteous but just state that you understand that there may be a home left behind that you would be willing to pay cash for.Let them know the troubles of tryinig to sell a home the traditional way then tell the the positives of selling it to you.I personally don't go after widows because they may still live in the house and have some sentimental attachment to it. you want people who live across the country and don't even know the home exists.

I'm currently getting in touch with the widow for another potential deal.

I am the solace of the widow, the comfort of old age, the cornerstone of security against misfortune and want.
