Rehabbing a Rowhouse

Does anyone have knowledge on rehabbing a rowhouse? My main concern is replacing the walls with drywall and adding central air units.

Any tips? Thanks

No different than rehabbing any other house. Why do you want to replace the walls?

I’m rehabbing a rowhouse in Philly. You’re probably concerned because your walls are plaster. It’s messy to clean up, but worth it. I put central air in mine, but it was easy since I tore my plaster walls and ceilings out. I put the unit on the roof, btw.
