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
$23,361
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
5.31%
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.
