My main focus is just wondering which might make more profit on the short and long term you know as In monthly income and Also over all winnings .

first you have to decide what you want to do in the note business.. what most of the responses are talking about is buying bad debt.. and 2nds at that which this is the most risky and the most work..if your looking for work and risk and job then that kind of note investing is for you.If your looking for Passive income with no work and Limited risk then you simply need to align with a great HML who takes on private clients or those that understand where performing notes are generated.. we have done over 1700 performing notes for clients that last 5 years and really don't advertise at all. simply because once you get conservative investors in your program it just feeds itself.. deal flow is the key right now.. most have a hard time finding quality. finding defaulted seconds is easy.. and the most risky. 

My first project was simply renting our townhouse while our house was being built but that's not what I'm here to discuss!

It doesn't sound like a very appealing tenant so I'm torn on what to do but I guess simply because she mentioned the M word (which I never use around tenants) I would probably replace it and have that one cleaned up as a backup unit.

They would simply sell it to another person for market value.

The benefits can be incredible and the opportunity to work in a niche that is a win-win for both investors/sponsors and renters alike is even more rewarding.

This mortgage is the only debt I have so I see it as a win-win as I personally don't have to pay as much on the mortgage and my family isn't living in a crowded space with rude neighbors. 

We simply cannot take this person anymore.

I like Omar's suggestion of allowing a mentee to simply be a fly on the wall for existing business you are working anyway. 

Deduct an appropriate amount from what you think it will return.All that said, if you have plenty of other investments to make you comfortable and you are simply intrigued with owning a large manufacturing facility in Wisconsin I say do as much research as possible and then go for it.
