I think the bigger issue is lack of communicaiton and how they handle the situation. 

They can find the properties, you handle the renovations, and you split the proceeds based on what you bring to the table.Go to BUILD YOUR TEAM at the top of your screen, and you can search for other MEMBERS or LOCAL MEETUPS.

I’m looking for honest feedback (don’t worry, I can handle the truth!).

As a landlord, what is the best approach to handle this case?

Of course blaming me, complaining about other people, talking about her medical issues and son and how they need a place without stairs and need to move, and on and on.How are other landlords handling this?  

Seeing how they’ve handled similar projects—especially when things didn’t go as planned—can give valuable insight into their problem-solving skills and reliability.How do you usually gather this kind of information?

The only thing that is stopping me is that I will most likely need to upsize my gas houseline to a bigger pipe since tankless wh require more BTUs, and my water heater is at the other end of my gas meter.Another thing to note is if your existing gas service can handle the additional tankless water heater loads.

He just doesn't have the wisdom to know how to avoid/handle that.

If you're handling RE and you have a partner, a lawyer is a very good idea.

I’d say it’s all about finding the right property management team you can trust to handle the day-to-day.
