What does the “pre-war + M train” filter mean on this page?

It narrows the eligible buildings to those tagged as pre-war (built before 1947) and located near the M train corridor, so you can compare similar housing age and transit access at the same time.

How many buildings match these filters in Flatiron right now?

Openigloo shows 106+ buildings for this Flatiron + pre-war + M train scope as of 2026-07-07.

Does “pre-war” tell me what utilities, heat, or hot water will be like?

No. Building age can correlate with certain systems, but the actual setup varies. Confirm heat/hot water details, appliance condition, and any recent upgrades with the building directly.

What should I ask the leasing office before applying?

Ask about move-in timing, the exact fee schedule (deposit, any non-refundable fees), lease start flexibility, laundry access, and any building rules that affect your daily routine.

Are there any data limits I should keep in mind when using Openigloo?

Openigloo signals and community Q&A help you shortlist, but they can’t replace a direct conversation with leasing. Always verify the specifics for the exact unit you’re considering.

Which neighborhoods are trending right now in this scope?

East Village with 11,857+ buildings; Hell's Kitchen with 6,943+ buildings; Yorkville with 9,328+ buildings; Lenox Hill with 8,357+ buildings; Kips Bay with 4,472+ buildings.

How do I use the ratings on Openigloo when comparing older buildings?

Use ratings as a starting point, then look for recurring themes in tenant Q&A from rated buildings—especially on maintenance responsiveness, noise, and day-to-day building conditions.
