Homeowners Insurance for a NYC Co-Op: How much?

Hi, our homeowners insurance is coming up for renewal and we were wondering if we had too much or too little insurance and whether our premiums were in line. Apartment: 3 BR Coop on the east side 1) Building Property Protection: $100K (deductible $500) 2) Personal Property: $50k (deductible $500) 3) Additional Living exp: upto 12 months 4) Liability Protection: $1 million 5) Loss assessment $1k each occurrence (deductible $250) 6) Annual premium: $500/year Note: the above is what we have taken out personally and is different from the Coops own insurance. Does any of this seem out of line?
