What this means for you Summary

Snapshot

  • This is a 3-bed/2.0-bath single-family listed at $434k.

Deal economics

  • At list price, monthly cash flow is $-763 ($-9k/yr) — negative.
  • To cash-flow at today's rent, offer at most $299k (31.1% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $248k (42.9% below list).
  • Recommended offer: $248k (42.9% below list) — sets the bar for 1% rule.
  • Cap rate 4.2% vs local median 2.6% in Birch Bay — 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 62/100 on livability (#406 in WA) — a middle-class / working-renter tenant base. Strengths: housing A; Watch: cost of living D+, health & safety D, amenities F.
  • Blaine School District (town): math 49% / reading 55% proficiency, ranked #120 of 291 in WA (top 41%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
  • Zoned schools: Blaine Primary School (463 students, 50% FRL); Blaine High School (609 students, 46% FRL) — zoned schools average 48% FRL vs 33% district-wide (15 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: Rents rising (+3.1%/yr); 461 active listings in the ZIP; 1 comparable units currently listed for rent nearby; solid renter incomes; 1,190 units permitted in Whatcom County in 2024 (327 in 5+ unit buildings).
  • This rent runs 34% of the median local income ($87k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Forward outlook

  • In year one you build about $46k of equity ($3k loan paydown + $43k appreciation (10.0% local appreciation)).
  • Whatcom County population projected at +28% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
  • By year 2, paydown + projected appreciation supports a ~$75k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

  • It's been on market 51 days — a 3% lower offer ($421k) is reasonable based on typical stale-listing flexibility.
  • 4 sale attempts since 20y 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 $290k; 50% above their basis — modest negotiation headroom, anchor on the comps not their cost.
Recommended offer $247,778 (42.9% below list)

Questions for the listing agent

  1. What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
  2. It's been on market 51 days. Have you received any prior offers? Is the seller open to a 43% concession, seller financing, or rate buy-down credit?
  3. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
  4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  5. Schools are F-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
  6. The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
  7. 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.
  8. 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.
  9. How much new for-sale + rental construction is in the pipeline within 1–3 miles? Heavy new supply typically softens prices + rents 12–24 months out; constrained supply supports both.

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.
