The existing rail infra was fucked over by NIMBYs before it even got started, and all future efforts related to public transit get screwed over as well.
A ton of money was dumped into Mopac/Loop 1 and so much of it ended up in walls to cut the sound down in high-value residential areas instead of improving congestion areas.
A large portion of real estate/housing is being purchased by investors tossing money way over asking prices, driving up the local cost. Housing in the area has now raised by ~2X in most parts of the city and it's outskirts. I was on my way towards being able to purchase a house in 2020 before the pandemic struck, then with the economic downturn a massive influx of outside investors took the market by storm. Between mid-2020 and now the target area I've been keeping an eye on went from a median home value of $275k to $485k. Many are now being relisted for rent and the rental market is rising fast as well.
I think we're already seeing the same gentrification/cost of living rise, and it's only the beginning.
