Hi there.
While I do not live in Pomona, I do live in Rockland County and hopefully can answer a few questions you have.
Pomona is quite affluent, average income is over $100,000. Haverstraw is about 6 miles away from Pomona. Pomona's school system is East Ramapo School District. I believe they are served by the police of either Suffern or Ramapo. Taxes are high (school tax makes up a large portion) depending on the value of your condo, probably $4,000 to $7,000/year.
Pomona is small and family minded. I'd say it's a pretty typical suburban town. It's pretty quiet. It's also a nice point that it's also very close to the New Jersey border - the Palisades Parkway & NYS Thruway are minutes away (hello cheap gas!)
Rockland County has a sytem of public buses called Tor of Rockland as well as Coach/Red & Tan lines which make trips to the city. There is a train you can catch from Suffern that goes to NYC via Hoboken PATH (which makes a stop at 14th Street). I'd say the majority of Rockland County commutes to NYC on a daily basis.
HTH!
