I am considering doing this but should I charge a fee to write up and get the lease addendum signed?

Getting a mother-in-low to co-sign is not the answer.

It used to be my job to protect our celebrity clients from so called investment specialists who promised more than the investment was worth and delivered less or nothing at all.

He signed a binding contract and then changed his mind.

Sometimes the trailers I buy do still have titles on them, in which case we either have the seller cancel the title with the DMV before we close, or we have them sign the title into our name, and then we cancel the title ourselves.

I don't think a degree will help, I'd sign up for courses and learn as much as you can.

I ended up signing with them as well - 3 months in to the lease so far and it's going well.

However, I cannot be signed into both her account and my own VRBO for my 2 properties at the same time.

When you sign almost all mortgage closing packages, you are signing an Occupancy Clause that states you are intending to live in the home for 12 months.  

Seeing the success of others and resenting them rather than celebrating them.
