To understand the rental market, brokers and recent first-time renters recommend searching the Internet for listings and getting recommendations from friends who already live in the city. That elusive $2,000 one-bedroom apartment, for example, can be found in neighborhoods like Harlem, Morningside Heights and Washington Heights, probably in a nondoorman building. And the average price for studios is below $2,000 in the East Village, the Lower East Side and neighborhoods north of Midtown.

Most real estate agency Web sites have guides that explain the intricacies of New York’s rental world. Citi Habitats sends agents to about 20 universities nationwide to offer seminars on what it takes to get an apartment.

Cullen Hilkene, an agent who ran a Citi Habitats seminar at Princeton University last week, said that prospective renters need to know the limitations the market might impose on them. “I give them information so they can figure out how they’re going to be able to live in New York,” he said. “It’s better to know sooner rather than later that they need to bring in a roommate because they won’t be able to rent a studio on their own.”

Alex Sooy, who moved into a two-bedroom near Union Square last June with his roommate, David Isaacs, said he knew the first thing they had to decide was whether to use a broker. For placing you in an apartment, brokers typically charge 15 percent of the annual rent or 1.8 times the monthly rent, which means $3,600 on a $2,000 apartment.

Mr. Sooy said he tried looking online for no-fee apartments, “but we would have to go to all these places on our own and work individually with the landlords and that was an overwhelming process.” Like many recent graduates, Mr. Sooy and Mr. Isaacs planned to travel after graduation and they had only three days to hunt for an apartment. “We hated to pay the fee, but it was the easiest way to look at a number of places in a row without having to do so much legwork ourselves,” Mr. Sooy said.

Their goal was to find a $3,000 two-bedroom downtown. They visited eight apartments with brokers from two firms before choosing one near Union Square with two real bedrooms, as opposed to ones carved out of a living room, for $3,600. They did not need guarantors because Mr. Sooy works for a consulting firm and Mr. Isaacs works for an investment bank and their combined income satisfied the landlord.

Mr. Sooy says his rent is much more than the $400 a month he paid when he was in school and it eats up more than 50 percent of his after-tax income. “I would prefer to have more disposable income,” he said, “but it’s a good apartment and the location is great.”
