@Mark Cruse knows Baltimore very well and can probably give you good advice. 

However, I would like to gain some practical experience in the world of Notes as well.

Absentee owners are a plus as well...you're really looking to find someone who already has a property manager, does not live locally, and is underperforming (but with a good property/location).

Well worth every penny. 

I have both courses and others as well.

Many people are quick to tell me that I will never be able to collect on any judgment, and I’m well aware of this likeliness.

I'm looking for a property management software that will allow me to upload documents as well.

This is not to say this is the only successful method of real estate investing, but as I'm sure you're well aware, with current interest rates and overall market conditions, sourcing and acquiring LTR deals is difficult unless you're going off-market. 

I know there are monthly meetups around town as well that are hosted by individual investors.

The plan is to short term rent some rooms, or mid-term, and live in the primary until its doing so well I have to move out and refocus on a previous renovation that has stopped until this one is complete.
