In February, rental rates at one-bedrooms and two-bedrooms in Upper West Side buildings without doormen fell, according to a report put out by real estate firm MNS. Listings for one bedrooms without doormen were 10.3% less expensive on a month-over-month basis, and listings for two-bedrooms were 5.6% less expensive.

Rents are still well above their levels in 2012 — in fact, citywide listings in buildings without doormen are 30% more expensive than they were two years ago, says MNS. But as we’ve written before, the increase in rents seems to have slowed, or even reversed somewhat, in recent months. Because of the methodology behind the survey, the changes in rates could just have to do with a change in the mix of available listings, as opposed to changes in the prices of individual apartments.

Here’s where MNS gets the data: The Manhattan Rental Market Report ™ is based on data cross-sectioned from over 10,000 currently available listings located below 155th Street and priced under $10,000, with ultra-luxury property omitted to obtain a true monthly rental average. Our data is aggregated from the MNS proprietary database and sampled from a specific mid-month point to record current rental rates offered by landlords during that particular month. It is then combined with information from the REBNY Real Estate Listings Source (RLS), OnLine Residential (OLR. com) and R.O.L.E.X. (Real Plus).
