What this means for you Summary

Snapshot

• This is a 1-bed/1.0-bath condo listed at $275k.

Deal economics

• At list price, monthly cash flow is $465 ($6k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($3k rent vs $275k).
• Recommended offer: $258k (6.0% below list) — sets the bar for market timing.
• Cap rate 8.3% vs local median 4.3% in White Plains — top-decile yield for the area; either an underpriced asset or a hidden risk that comps aren't pricing in. Stress-test before assuming the spread holds.

Location & tenants

• Location reads 71/100 on livability (#410 in NY) — a middle-class / working-renter tenant base. Strengths: commute A+, employment A+, crime A-; Watch: amenities F, cost of living F.
• White Plains City School District (urban): math 49% / reading 54% proficiency, ranked #313 of 590 in NY (top 53%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Zoned schools: White Plains Middle School (math 36% / reading 53%, grade D, #348 of 729 statewide, top 50%, 1,517 students, 50% FRL); White Plains Senior High School (math 89% / reading 67%, grade A-, #577 of 1,100 statewide, top 52%, 2,220 students, 53% FRL).
• Market conditions: Rents rising fast (+6.4%/yr); 111 active listings in the ZIP; 40 comparable units currently listed for rent nearby; rentals leasing fast (median 14d on market — plan ~1-2 weeks tenant-placement turnaround); high-income renter base; 954 units permitted in Westchester County in 2024 (649 in 5+ unit buildings).

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $8k of value loss. Plan a longer hold.
• Westchester County population projected at +10% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
• At projected returns (-3.0% appreciation + 6.4% rent growth), your $77k cash investment doubles in ~9 years — after that, you're playing with house money.

Negotiation context

• It's been on market 76 days — a 6% lower offer ($258k) is reasonable based on typical stale-listing flexibility.
• 4 sale attempts since 8y ago with the ask held roughly flat each time — persistent listings suggest the price (not the market) is what's stuck; bring a comps-based counter.
• Current owner paid $215k; 28% above their basis — modest negotiation headroom, anchor on the comps not their cost.

Risks & watch-outs

• Climate carrying-cost: major wind risk, 27% chance of damaging wind over 30y; extreme-heat days projected 7→15/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $258,499 (6.0% below list)

Questions for the listing agent

1. It's been on market 76 days. Have you received any prior offers? Is the seller open to a 6% concession, seller financing, or rate buy-down credit?
2. Built in 1964 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
3. Any open or pending special assessments — roof, HVAC, plumbing, elevator, façade? What's the per-unit balance and payoff schedule, and is the seller paying it off at close or rolling it to the buyer?
4. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
6. What's the average days-on-market for RENTAL listings here right now (not sales)? A rising rental-DOM trend means longer vacancies and softer asking-rent achievability than the comps imply.
7. What's the recent tenant-quality profile in this submarket — average credit score on applications, eviction rate, late-payment / NSF rate, and stable-employment percentage? A property-management company in the area should have these aggregated.
8. How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

For passive investors: Depreciation is non-cash, so a rental often shows a tax loss while cash-flowing — sheltering income. Rental losses are passive: they offset passive income freely, and up to $25,000/yr can offset ordinary (W-2) income if you actively participate and your MAGI is under $100k (phasing out to $0 by $150k); unused losses carry forward. On sale, claimed depreciation is recaptured at up to 25%, and gains may owe capital-gains tax (a 1031 exchange can defer both). Figures are a year-1 estimate at your 24.0% rate — not tax advice; consult a CPA.
