Investment Insights
Based on property information with market context.
Located at 321 Spring Street in Ossining’s Sparta district, this beautifully maintained two-family duplex was built in 1930 and sits on a 0.1096-acre lot. Each apartment is approximately 1,000 SF and includes two bedrooms, one updated bathroom, a living room, kitchen, dining room, and a large bright 4-season sunroom. Oak hardwood floors, stucco walls, and solid wood trim add character throughout.
The full, unfinished basement offers practical separation with two laundry stations, one for each unit, along with plenty of storage. The shared backyard includes a large hardwood deck, and the home also provides an ample driveway with off-street parking.
Heating is oil-based, and cooling is provided by wall/window unit(s) and window unit(s). Public water and public sewer serve the property. Residents may also value the walkability to Arcadian Shopping, the Scarborough-on-Hudson train station to GCS, and the Hudson River Front.

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
$38,956
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
5.53%
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.
