What this means for you Summary

Snapshot

• This is a 2-bed/1.0-bath townhouse listed at $240k. Condition is rated good.

Deal economics

• At list price, monthly cash flow is $-33 ($-393/yr) — negative.
• To cash-flow at today's rent, offer at most $235k (2.0% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $211k (12.0% below list).
• Recommended offer: $211k (12.0% below list) — sets the bar for 1% rule.
• Cap rate 6.1% vs local median 3.6% in Cortland — 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 76/100 on livability (#184 in IL, #3,520 nationally) — a middle-class / working-renter tenant base. Strengths: crime A+, cost of living A+, housing A+; Watch: amenities F, commute F.
• Dekalb CUSD 428 (suburban): math 11% / reading 16% proficiency, ranked #541 of 620 in IL (top 87%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
• Zoned schools: Cortland Elementary School (math 8% / reading 8%, grade F, #1,627 of 2,056 statewide, top 81%, 519 students, 0% FRL); Huntley Middle School (math 12% / reading 16%, grade F, #529 of 665 statewide, top 80%, 934 students, 0% FRL); Dekalb High School (math 18% / reading 28%, grade F, #312 of 693 statewide, top 46%, 2,083 students, 0% FRL) — zoned schools average 0% FRL vs 48% district-wide (48 pts lower); this property's tenant base skews higher-income than the district average.
• Market conditions: 53 active listings in the ZIP; 2 comparable units currently listed for rent nearby; 260 units permitted in DeKalb County in 2024 (73 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 $7k of value loss. Plan a longer hold.
• DeKalb County population projected to shrink 5% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.

Negotiation context

• It's been on market 88 days — a 6% lower offer ($226k) is reasonable based on typical stale-listing flexibility.

Recommended offer $211,035 (12.0% 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 88 days. Have you received any prior offers? Is the seller open to a 12% 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 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?
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.
