@George Torres
In NYC, coops are generally less than condos and SFRs, for a number of reasons, some of which @Matt R.pointed to. LA might be different, though. I suggest taking another look at the comps or maybe enlist a broker for a professional opinion.
Some things to consider for yourself and for your end buyer:
1. Is the coop in a good financial position? No one wants to buy into a dud.
2. How much is the monthly maintenance fee?
3. What are the requirements of the board? One might be able to get a loan with 20% down, but a lot of coops require 25-35% down.
4. Is the board easy, ok or difficult?
5. What are the board's reserve requirements? Some boards might require 1-2 years of maintenance + mortgage, etc. after closing.
6. Flip tax?
7. Upcoming assessments?
Coops are somewhat of a different animal. Do some more research, particularly on that coop you are interested in. Some buildings have certain reputations, good or bad.
Best of luck!
