How to Value a NYC Apartment: A Fair Rent Formula

The Formula in One Line

Fair monthly rent = neighborhood median for the bedroom count × size × finish × light and view × bathrooms × amenities × spot in the neighborhood × furnished × length of stay × time of year, plus a dollar amount for utilities that are included.

Each factor is a small multiplier around 1. A factor of 1.10 means "10% more than typical", 0.92 means "8% less". Multiplying them keeps the adjustments in proportion: a doorman adds more dollars to an expensive apartment than to a cheap one, which is how the market behaves.

Step 1: Start from the Right Median

The biggest mistake in pricing New York rentals is starting from too wide an area. Manhattan’s median one-bedroom asks $4,875 a month, but inside Manhattan the neighborhood medians run from $2,715 in Washington Heights to $7,005 in Tribeca. A borough average prices neither one correctly.

So the starting point is StreetEasy’s median asking rent, October 2026, for the neighborhood and for the same number of bedrooms. StreetEasy publishes these monthly for about 170 areas. Where a neighborhood has too few listings for a reliable figure, the method falls back to what the neighborhood’s overall median implies for that size, and then to the borough.

A private room is priced as a share of the whole apartment: the median for the apartment’s bedroom count, divided by its bedrooms. A room in a three-bedroom in the East Village starts at $8,120 ÷ 3 = $2,707.

Step 2: Size, Read from the Photos

Rent does not double when floor area doubles. Within the same bedroom count, the method uses an elasticity of 0.55: a place 10% larger than usual is worth about 5% more, and one 20% smaller about 12% less. The usual sizes it compares against are 450 square feet for a studio, 675 for a one-bedroom, 950 for a two-bedroom and 1,250 for a three-bedroom.

Most listings do not state square footage, so it is estimated from the photos: each room is measured against objects of known size (a queen bed is 60 by 80 inches, a kitchen counter is 36 inches high, an interior door is 80 inches tall), the same room seen from several angles is counted once, and rooms that are not pictured are added at a standard size. Listing photos are usually wide-angle, which makes rooms look larger, so the estimate leans on counted objects and floorboards rather than the feeling of depth.

Step 3: Finish, on a Five-Point Scale

Kitchens and bathrooms decide the finish level. Furniture, decor and tidiness do not: a beautifully staged dated apartment is still dated.

• 1, worn (-16%): damaged surfaces, a very old kitchen or bathroom.
• 2, dated (-8%): clean but old. Laminate counters, a plain tub with a curtain.
• 3, standard (no change): an ordinary well-kept New York rental.
• 4, renovated (+10%): stone counters, matching stainless appliances, new tile, a frameless glass shower.
• 5, top of the market (+22%): condo-grade throughout, floor-to-ceiling windows, central air, a spa bathroom.

Light, ceiling height and view are scored separately and together move the number by a few percent either way.

Step 4: Amenities and Bathrooms

Each amenity adds a share of rent: a doorman about 7%, laundry in the unit about 4%, private outdoor space about 4%, an elevator about 4%. The doorman, elevator, gym and in-unit laundry figures follow a published regression of New York listings by RentHop; the others are our assumptions.

The median listing already has some of these, so the method subtracts about 6% before adding anything, which stops a typical elevator building from being counted as a premium one. An extra full bathroom beyond the usual number for the size adds about 5%.

Step 5: Furnished, Length of Stay and Season

StreetEasy’s medians describe unfurnished apartments on 12-month leases. A furnished place adds about 15%, and a stay of three months or less adds about 8% more per month, because the landlord or tenant carries the cost of turning the place over more often. Together that is about 24%, the low half of the 20% to 40% range New York brokers publish for furnished short-term rentals.

Then the calendar. Citywide, asking rents peak in July and bottom out in December, a swing of about 6% measured from StreetEasy’s own series.

A Worked Example

Take a furnished one-bedroom in the East Village for a summer stay, June 1 to August 15: renovated, about 760 square feet from the photos, bright, in an elevator building with a dishwasher. The estimate starts at $4,045 and ends at $6,115 a month, with a likely range of $5,685 to $6,545. The chart shows each step.

What This Method Cannot Know

It cannot see noise, smells, a difficult landlord or how a block feels at night. It reads location only as distance to trains, parks, campuses and work districts, and never looks at who lives in or near a place.

Several multipliers are assumptions rather than measured facts, and its accuracy has not been scored against signed leases yet. Treat the result as the middle of a range that is usually about 8% to 15% wide on each side.

How to Use It on Your Own Place

1. Look up the median for your neighborhood and bedroom count in the table linked below.
2. Be honest about finish: compare your kitchen and bathroom to the five levels, not your furniture.
3. Add the amenities you really have, then subtract a little, because the median already has some.
4. If you are subletting furnished for a summer or a semester, add the furnished and short-stay premiums.
5. Check the lease and the law before you price: a rent-stabilized tenant generally may not charge more than the legal rent, plus 10% if furnished.
