The Four Phases of a Westchester Sale

Phase 1 — Pre-listing preparation (3-6 weeks): This is the phase most sellers underestimate. Professional photography requires a clean, staged home — usually 1-2 weeks of decluttering, minor repairs, and staging coordination. The property needs a market analysis to set the right price, which requires pulling and analyzing the last 90 days of comparable closed sales. Disclosure documents need to be assembled. The listing agent's marketing plan and timeline need to be confirmed. Sellers who compress this phase to one week typically launch with rushed photography and without adequate pricing analysis.

Phase 2 — Active marketing (1-8 weeks): From listing to accepted offer. In top-tier Westchester school districts in spring, correctly priced move-in-ready homes go under contract in 14-21 days. In second-tier districts, 3-5 weeks is typical. Properties priced above current comparable sales sit until either a price reduction or a market shift brings buyers to the price. The most consequential decision of the entire sale — the list price — is set at the transition from Phase 1 to Phase 2.

Phase 3 — Attorney review and contract (1-3 weeks): After verbal offer acceptance, both attorneys negotiate the formal contract. In New York, neither party is bound until both attorneys sign. This phase typically takes 1-3 weeks depending on attorney responsiveness and the scope of contract negotiations.

Phase 4 — Contract to closing (6-12 weeks): After contract signing, the buyer completes their due diligence (inspection, appraisal, mortgage underwriting for condos; board package for co-ops). Single-family home closings typically occur 8-10 weeks after contract signing; co-op closings add the board process and run 12-16 weeks.

What Controls the Timeline — And What Sellers Can Influence

Not all timeline variables are within the seller's control. The things sellers control: the quality and pace of pre-listing preparation, the accuracy of the list price, the responsiveness of their attorney during contract review, and how quickly they can accommodate showings once listed. The things sellers don't control: how long the buyer's mortgage underwriting takes, the board approval timeline for co-op purchases, and the specific closing date that works for both parties' concurrent transactions.

The most impactful seller decisions on timeline: setting the correct list price from day one (an overpriced listing adds 4-8 weeks of DOM before a price reduction and then the additional marketing time at the reduced price) and choosing a responsive attorney (attorney review delays of 1-2 weeks vs. 3-4 weeks are almost entirely within the attorney's control and have meaningful timeline implications).

Planning the Timeline Backward from Your Target Date

Sellers who have a target move-out date — a new home purchase closing, a school year end date, a lease start for the next place — should plan the selling timeline backward from that date.

For a June 30 target closing: contract needs to be signed by late April (6-8 week typical single-family closing timeline), offer acceptance needs to be in early April, listing should go live in March, preparation should begin in January or early February. This is a 5-month process from preparation start to closing. Sellers who begin thinking about listing in March for a June close are already behind the comfortable timeline and will be working compressed.

For co-op sellers: add 6-10 weeks for the buyer's board approval process. A June 30 co-op closing requires a March contract signing, which requires a February offer acceptance — 2 months earlier than the comparable single-family timeline. Co-op sellers who don't account for this consistently close 2-3 months later than planned.
