Investment Insights
Based on property information with market context.
This well-maintained duplex offers two separate units with distinct layouts. The upper unit features 2 bedrooms and 1 bathroom, while the lower unit has 1 bedroom and 1 bathroom. Both spaces have been refreshed with new flooring and fresh paint throughout, supporting a clean, move-in-ready experience for tenants or owner-occupants.
The property is located in Clear Lake, IA, just moments from Main, placing it within convenient reach of local activity. The overall site is listed at 0.16 acres, with a total property size of 1,243 square feet.
From a practical perspective, the configuration supports flexible living and leasing options. An owner can occupy one unit while renting the other, or lease both for rental income. The addition of two brand-new central A/C units is also notable, as it helps improve comfort and reduce near-term major maintenance concerns for whichever unit(s) are occupied. Overall, it presents a straightforward duplex setup with recent interior updates and updated mechanical comfort.

Financial Insights
Estimated NOI and Cap Rate
NOI = area × lease_rate × (100 − vacancy) / 100 × (1 − expense_ratio). Net Operating Income — what the owner takes home each year before mortgage payments and income tax. Effective rent (asking rent minus vacancy losses) minus operating costs (taxes, insurance, maintenance, management).
NOI / Yr
$10,610
Cap rate = NOI / list price × 100. Capitalization rate — annual return on a fully cash purchase, before financing. NOI divided by price. Higher means more income per dollar invested, but usually also more risk or older condition. 5–8% is typical for stabilized commercial property; double digits often signal distressed deals.
Cap Rate
3.69%
Suggested Prices Based on Cap Rates
Cap rates vary significantly by property type, market, and asset quality.
Typical U.S. stable-market ranges:
Multifamily — 4.5% to 6.5% (Class A in primary markets often sub-5%; Class C in secondary markets 6%+)
Industrial / Logistics — 5.0% to 7.0% (compressed heavily in recent years due to e-commerce demand)
Office — 6.5% to 9%+ (wide spread post-2020; CBD Class A vs. suburban Class B varies dramatically)
Retail — 5.5% to 8.5% (grocery-anchored on the low end, unanchored strip centers higher)
Hospitality / Hotels — 7.5% to 10%+ (higher due to operational risk)
Self-Storage — 5.5% to 7.5%
Medical Office — 6.0% to 7.5%
Net Lease (single tenant, credit) — 5.0% to 7.0% depending on tenant credit and lease term
Rules of thumb:
Primary markets (NYC, SF, LA, Boston, DC) trade at lower cap rates than secondary/tertiary markets, often by 100–200 bps (bps, aka basis points; 1 bp = 0.01%).
Class A assets trade ~50–150 bps tighter than Class B, and Class B tighter than Class C.
Cap rates move inversely with price — a lower cap rate means a higher price for the same NOI.
Spread to the 10-year Treasury is a common benchmark; historically 200–400 bps over the 10-year.
