In the past, home owners wanting to participate in the rental program were required to buy the parapet railings. However, they recently changed the rules such that you can opt for the railings (extra cost) or you can opt to have the wall built at 3 feet tall vs 2 feet with a railing. Building the wall to 3 feet is not an additional cost to the home purchase price. Therefore, since the cost of the railings is considerable, we've opted for the 3 foot walls.
That's about it in updates. I believe they are set to start construction next week. It's starting to feel more real now.
