What this means for you Summary

Snapshot

• This is a 1-bed/1.0-bath condo listed at $80k.

Deal economics

• At list price, monthly cash flow is $395 ($5k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $80k).
• Cap rate 12.2% vs local median 2.5% in Washington — 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 73/100 on livability (#1 in DC) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, employment A+; Watch: crime F, cost of living F.
• District Of Columbia Public Schools (urban): math 33% / reading 40% proficiency, ranked #8 of 32 in DC (top 25%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 65% free/reduced lunch — lower-income household profile, screen leases tightly.
• Market conditions: Rents rising fast (+6.1%/yr); 276 active listings in the ZIP; 40 comparable units currently listed for rent nearby; rentals at typical pace (median 25d on market — plan ~3-4 weeks tenant-placement turnaround); 1,737 units permitted in District of Columbia in 2024 (1,506 in 5+ unit buildings).
• This rent runs 33% of the median local income ($58k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $553 of loan paydown is wiped out by about $2k of value loss. Plan a longer hold.
• District of Columbia County population projected at +50% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• At projected returns (-3.0% appreciation + 6.1% rent growth), your $22k cash investment doubles in ~5 years — after that, you're playing with house money.

Negotiation context

• Only 2 days on market — expect competitive offers; lowballing is unlikely to land.
• Current owner paid $14k; list at $80k implies a 473% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

• Watch-outs: HOA is 23% of rent; built in 1958 — expect roof / HVAC / electrical / plumbing capex.
• Climate carrying-cost: extreme-heat days projected 7→14/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $79,999

Questions for the listing agent

1. Built in 1958 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
2. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
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. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. 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?
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.
