I just don't want all of my savings sitting in a bank account, I want to invest my money to have a more comfortable life in the future.

What demographic areas are you comfortable with?

If you are comfortable with your new mortgage payment after you refi, I would totally do that. 

Your husband could then commute in relative comfort and use the commute time on the train for podcasts, reading, relaxing.

I’ve done quite a bit of research on BiggerPockets, youtube, podcasts, and still have a few remaining questions before I feel comfortable enough to take the plunge.1) Have you ever worked with a wholesaler directly?

Since we will be using it as Section 8, chances are the room that it is located in would go to a child, and I would rather not have to deal with giving a child access to a sink in their carpeted room.

Three things:1) After we moved when I was a child, my parents rented out our old house so I had seen RE work before.2) I am a mathematician and I'm compulsive about running the numbers, so I knew it was a good deal.3) I always knew that I wanted to get rich.

I'm the only child and she is divorced. 

Can you make the cash out pay for itself and if the answer is a comfortable yes at those interest rates, then do it. 

If you are self-managing now and comfortable with the process of taking service calls, it won't be much different when you are out of state.
