My tenant just told me that he wants his fiance and their one year old child to move in with him in a few weeks.

Then they took over your child's education with public schools.

Renting to college kids will give one direction to go ( 9 months of click click click), renting to mostly boomers another(think US Mail). 

We have a young family (one child) and are looking to make our money work for us rather than just waiting until retirement.Opportunity (and where I could use advice):I came across a social media post from a former high school classmate—now a loan consultant—who was seeking investors for potential flip or BRRRR projects.

The beneficiary would be your family, I.e a child or whoever the trust is essentially for at the end of day, and the trustee yourself.  

I also have my first child on the way due in about a month so I am considering if I want to take on the work of furnishing the unit, marketing it, and generally learning something new while I am learning to be a dad.

You can also pay your child out of the rental property as opposed to the LLC.

I'd wanted to just keep him because I just had my first child and don't really want to do a reno right now which the apartment does kinda need.

You say credit cards, loans, car repo, student loans, collections and child support.

I went through this learning curve with our red-headed step child property.
