Condo HOAs usually cover the maintenance of the shared building parts (HVAC, roof, plumbing outside the units, etc). One danger sign is a condo with a HOA that is too low - it likely means maintenance is being put off or done incorrectly or you're going to get hit with a special assessment soon.
Older buildings start getting hit with the "every 20/50 years" maintenance, and also get hit with lawsuits against the building/HOA itself. Those can start to add up over time.
And the size of the building can also affect it; a smaller building with the same amenities would have higher HOA fees.
I personally wouldn't touch them with a fifty state pole, but some people like it.
Sounds like it could have been a co-op which would include taxes in the HOA.
So 11 * 40 * 52 / 12 = 1906$/month + SS.
$15.40 for employers with 21 or more employees (including all domestic workers, regardless of the number employed) $14.50 for employers with 4-20 employees

But, you can subtract reasonable room and board fees, so actual cost could be lower if you had a spare room and someone was willing to take the job.
2k plus a room.
