I moved from an apartment after it was sold and approved for condo conversion. I did have first choice if I wanted to buy (I didn’t). Most residents moved before the 180 days was over and I was one of the last to leave. They ended up giving me $2k for moving expense (I moved myself for $500) and my complete security deposit without having to clean anything (they were gutting it anyways). If you do get the notice, it might be worth it to stick around for a while and see if you can get some freebies.
This was in SD in 2003 at the height of the craze. The people that bought are probably well underwater by now. They were listed at $420-500k for approx 1200sf 2bed/2bath directly under the flight path (had to ask people on the phone to hold when a plane passed). Rent was $1295.
