What this means for you Summary

Snapshot

• This is a 1-bed/1.0-bath manufactured listed at $45k. Condition is rated good.

Deal economics

• At list price, monthly cash flow is $-163 ($-2k/yr) — negative.
• To cash-flow at today's rent, offer at most $21k (52.3% below list).
• Meets the 1% rule at list price ($1k rent vs $45k).
• Recommended offer: $21k (52.3% below list) — sets the bar for cash-flow.

Location & tenants

• Location reads 65/100 on livability (#183 in MA) — a middle-class / working-renter tenant base. Strengths: crime A+, health & safety A, employment A-; Watch: schools D+, amenities F, commute F.
• Dennis-Yarmouth (suburban): math 31% / reading 42% proficiency, ranked #222 of 302 in MA (top 74%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Market conditions: 26 active listings in the ZIP; 657 units permitted in Barnstable County in 2024 (178 in 5+ unit buildings).

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $311 of loan paydown is wiped out by about $1k of value loss. Plan a longer hold.
• Barnstable County population projected at -20% by 2050 — secular population decline; favor cash flow + early exit over multi-decade hold.

Negotiation context

• It's been on market 251 days — a 12% lower offer ($40k) is reasonable based on typical stale-listing flexibility.
• 2 sale attempts; this cycle's ask has dropped $20k (31%) from the opening price — seller is motivated, your offer sets the floor, not the list.

Risks & watch-outs

• Watch-outs: HOA is 65% of rent.
• Climate carrying-cost: severe wind risk, 80% chance of damaging wind over 30y — expect insurance premiums to compound above CPI over the hold.

Recommended offer $21,468 (52.3% 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 251 days. Have you received any prior offers? Is the seller open to a 52% 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. 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. Schools are D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
7. 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?
8. 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.
9. 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.
10. 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.
