This unit has a listed monthly condo fee of $510 pr mo. The yearly taxes are listed at $1500 pr year. As for a cap on condo fees I would have to confirm. Not sure if you know this but the unit is listed as a "short sale".
If you would like me to futher research this for you and you are not currently working with an agent please let me know and I would be happy to help.
Kind Regards - Vicky
