The sales price of your property is affected by the following: location, size, condition, amenities (such as a fireplace), and, here in New York City, whether it's a co-op or a condo.
Another factor to remember is that your place *competes* against all others that are similar and on the market at the same time. If a buyer can find something similar enough or better at a lower price, the buyer will not buy yours.
The easiest and best way to get an idea of what it will sell for is to ask a real estate agent to come over and take a look, and bring comparable listings as well. Appraisals have their place, but they are expensive, and are usually reserved for insurance and mortgage purposes. An appraised price doesn't necessarily tell you the current market price, which is the only number that really matters when you're looking to sell.
