What to check before choosing a pre-war building near the SIM10 bus in Flatiron
- Expect older buildings (pre-war, built before 1947). Ask about heating setup, plumbing/elec updates, and how maintenance requests are handled.
- Use the SIM10 match to sanity-check your commute: confirm the exact stop proximity from the building’s entrance (walk time can vary).
- Before applying, verify current rent, required deposits, and any move-in fees listed for the specific unit—total monthly cost matters beyond the asking price.
- Check lease terms in the paperwork: move-in/lease start dates, renewal expectations, and any constraints tied to the unit or building rules.
- If you have pets or plan to share occupancy, ask the building directly about approvals and any documentation requirements, even when a building seems suitable on first look.
