They did this in NYC during the 70s/80s. The city owned a lot of foreclosed and burned down property (lots, brownstones, and buildings) and sold them for an extremely low low price. Some of these homes, lots, and hdfcs are worth a lot of money now and it definitely helped boost homeownership
Baltimore's housing stock is mostly rowhouses. The one thing about the $1 houses is that you can buy a house on a block fix it up, and the rest of the block can be leaning over, or the rooves could be collapsed. That's one issue I have with it. I wish more of 'us' invested in these up and coming neighborhoods.
