Investor read

• This is a 2-bed/1.5-bath townhouse listed at $70k.
• At list price, monthly cash flow is $842 ($10k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $70k).
• Only 8 days on market — expect competitive offers; lowballing is unlikely to land.
• Local home prices are declining (-3.0%/yr); year-one equity from $483 of loan paydown is wiped out by about $2k of value loss. Plan a longer hold.
• Location reads 76/100 on livability (#90 in MD, #3,396 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, housing A+; Watch: schools D, crime F.
• Baltimore City Public Schools (urban): math 7% / reading 16% proficiency, ranked #24 of 24 in MD (top 100%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 79% free/reduced lunch — lower-income household profile, screen leases tightly.
• Watch-outs: property tax is 3.9% of price; built in 1900 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: Rents rising (+2.3%/yr); 133 active listings in the ZIP; 40 comparable units currently listed for rent nearby; rentals lingering (median 45d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 50% of comp listings sitting > 30 days — soft ceiling on asking rent; solid renter incomes; 1,273 units permitted in Baltimore city in 2024 (1,104 in 5+ unit buildings).
• Baltimore County population projected to shrink 4% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
• 2 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.
• At projected returns (-3.0% appreciation + 2.3% rent growth), your $20k cash investment doubles in ~3 years — after that, you're playing with house money.
• 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.
• Cap rate 20.7% vs local median 6.0% in Baltimore — 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.

Questions for listing agent

• Built in 1900 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• Property tax is high relative to price — has the assessment been appealed recently, and will the sale trigger a re-assessment?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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?
• Crime grade is F in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
• 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.
• 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.
• 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.
