Well... I was 1/3 heir to a large apartment building that around that time was worth approximately 30 million dollars. It was not a family member of mine. But I had been performing most of the maintenance tasks in the building for about 4 years at that point.

I walked away from it over a couple things. The children of the owner were causing issues because I was entrusted with a lot of access and other things they didn't like, the owner had no concept of value of other people's time, and the owner had created a safety hazard in the building fire alarm system and ignored it even though i told him it needed to be fixed and was outside of my purview.

A few years after I left the fire alarm panel still had the same issue. The battery charger was not working correctly and the batteries needed replaced/upgraded. The Fire Marshall walked into the building after an anonymous tip I made and the panel was in an audible fault condition.

After I left my wife was sick and we were nearly homeless living in an old rv in a friend's driveway. It took us about 7 months to get back on our feet again.
