Property Transfer Options (Family)

[Gage Ealey]

Hi my name is Gage. I am a new real estate investor based out of the Baltimore area. 

Background: 

I purchased my first property (current residence) in baltimore, md during the summer of 2017. My plan was to live in the home for a few years before renting it out. The property location is northeast Baltimore, just a few min drive from multiple universities. 

Today:

I have now been living in my property for about 3 years and ready to rent it out. My mother lives in Columbia, MD and has a town home that she purchased about 6 years ago. She got the property as a foreclosure for well under market value. Since purchasing her home the area has continued to developed including a brand new multi-sport recreational park just a short walk from her front door.

Now that I am ready to move out and begin renting my property, my mother suggested me possibly taking over her home as my residence and she would look to buy a duplex where her and my grandparents would stay. 

My main questions:

1. If my mother and I want to come to some type of agreement on me taking over her home, what is the best way to go about this? She would essential like me to take over the current loan, however we aren't sure if the best option is for me to take out another mortgage by myself or make some sort of agreement on a 50/50 split of the home.

2. One concern I have is that my mothers home is worth significantly more than what I would be paying for it. Is there a solution in which I can make her a part owner of my current residence?

Any help or experience anyone has would be greatly appreciated.
