People try to say "Well it's technically a service dog, but..." 

I network with many investors in the scranton area as well as Vacation Rental investors in the poconos!

I’m committed to keeping my options open and continuing to learn about being a landlord to ensure I’m well-prepared for my first purchase.To improve my ability to analyze deals, I’ve developed a two-part plan:Join a local BP meet-up group to discuss my goals and support others.Continue learning and engaging with the BP forum.Thank you again for your guidance—it’s truly appreciated!

Selling an existing, well-performing asset has some risks.  

Hello BP Team,I hope all is well!

Will that be paid up by then as well?

Well said!

Even if you only averaged 2.8% appreciation annually, which if you've had it 20 years I have no clue how that's true given prices have well more than doubled in that time, youre skipping over the fact that you have been benefiting from that appreciation on the ENTIRE house, not just the % you paid for.  

Lots of areas that pencil very well on paper but the quality of renter you will get is going to eat into any profit you may think you are getting.

Based on the info in your post, my recommendation would be to turn these assets into well oiled machines and max out their NOI.
