I get that there is some mental benefits to paying off your mortgage but you could be investing it and have someone else pay off your mortgage.

There are thousands of different ways to invest that money, each will have their pros and cons, and also the time suck or mental brain damage that comes along with them.

It's a mentality of paying experts to do the work. 

Wealthy people have an abundance mentality.

I know without a doubt I will be doing deal, embarrassing the chaos of construction until the day I die or lose all my mental functions.

Scott Trench says it well…. carefully put together your “buy box”, be patient in waiting for that (realistic) deal to come, have your financing in order, and be mentally and emotionally ready to pull the trigger when you come across that deal.

I know the mental dilemma and challenges of it.

I would rather spend my mental energy elsewhere rather than on a creepy neighbor lol. 

My previous job was a Registered Nurse but after losing my 21-year old daughter to a senseless act of gun violence on August 3, 2015, I could no longer handle the mental and emotional demands of nursing.

His Fiance either knows and doesn't care, doesn't know and won't believe you, or he isn't mentally ill and has some other agenda.
