Next year, I plan to purchase a second home and move into it.

But we moved out the low rent tenants and after the rehab we filled all units with market rent tenants.

Hello,I have invested in a few properties meant for long-term renting.I have also since started a rental property management company that operates in areas we know very well (ascendiadynamics.com)Porto and Lisbon are very expensive areas at the moment. 

You could also do a 1031 and trade up, could get into a nicer area

Maybe look at PropertyRadar, PropHawk, PropStream and Podio. 

I work out of my basement and have been trying to find a location near me that rents out individual offices. 

And take the roof off and build up.

With many heirs and a 50-year history, you have no idea what skeletons could be hiding in the closets.

@Bryon Andrews was spot on in his advice too - do some Zillow and FB Marketplace surfing every few weeks to see what rents in the blocks near your property have been renting for recently, and track how those fluctuate over time for a few months.
