Personally, I would hang on to the cash.  

I've been informed that completing the course alone may not be sufficient to pass the exam, so I’m seeking advice on how to prepare effectively once I complete it.Currently, my only other resources include a YouTube video, five practice exams, and a textbook.If you have any additional suggestions—whether online or in-person, paid or free—that could help me effectively prepare for the exam, I would greatly appreciate them.

I would personally put them in notice just because they never tried to communicate it on the back end of fixing it.

They do not want the other person's name on the deed or the mortgage once the dirvorce is finalized.

Yes I have known it to work because the owner is not a push over, enforces policy and can make it run good......however, do you have the right personality to do this, AND if you move out can you continue to have the house run smoothly with no one in charge.  

In my opinion, an in person meetup > an online connection.You may want to consider making a connection here and meeting up for coffee or attending a real estate networking event.Best of luck!

I personally started in my local real estate market in Columbus Ohio.
