All but 1 tenant had to be evicted, was arrested, or went missing due to mental illness. 

If you don't have the additional mental bandwidth, can't deal with stress in healthful way or do not have much time to commit atleast 14 months of focus then do not build.

I think dismissing potential ideas on the basis of them being too complicated is an awful mentality and I would rather know exactly why it wouldn't work or a path that would make it work and then decide for ourselves if it's worth it or not based on the steps it would take.

This is a really hard mental challenge to overcome because you don’t know what you don’t know about other investments.

Other group homes for abused, veterans, and mental challenged usually have less opposition. 

The lead issue, coupled with an overall discomfort with the neighborhood and the home itself, has significantly impacted her mental and physical well-being.

Quote from @Kar Sun: My tenant's lease is coming to a close and I am relieved she will be moving soon.She has been paying on time but has been extremely unpleasant and rude.While the money does not smell my mental sanity is more important than money in this case.She sent me a registered letter stating that she feels "unsafe because we have not done the fixes the way she wanted it".She requests to have her witness for a walkthrough.In my state a walkthrough is required but I am not about to grant it to her to bring any witnesses as that is not in my contract.If she feels unsafe she does not have t be present.I also do not treat a final walkthrough with a tenant as a final sign off.This walkthrough does not include a detailed inspection of the plumbing and the appliances that will be done after she departs.This is simply for the visible cosmetic issues and should take less than 1 hr.  

You have the usual causes like drugs/alcohol problems, mental illness and then you have the working poor who remain homeless.

The “I helped the seller by a sub to purchase” and the “you screwed the seller by a sub to purchase” are both correct AND incorrect.Because it depends on whether the seller was provided with a full disclosure of the ramifications and possible consequences of entering into a sub to transaction; whether the seller is mentally competent to understand the ramifications and consequences, and whether the transaction is accomplished without lying to the lender.

But after enduring my first construction loan gut renovation, along with a couple of other partial ones, this issue has been one of my primary mental obstacles.
