Investment Insights
Based on property information with market context.
Welcome to Princes Bay. This oversized two-family semi offers a versatile layout across a main unit and a one-bedroom apartment, with tile flooring and updated interior finishes in multiple areas.
The main unit features a spacious living/dining area, a custom-tiled half bath, and an inviting eat-in kitchen with stainless steel appliances and natural stone backsplash that opens to a family room with sliders to the deck and yard. Upstairs, the primary suite includes vaulted ceilings, double closets, and a three-quarter bath with double sinks, along with two additional bedrooms and a full bathroom. The one-bedroom apartment offers flexibility with an updated granite kitchen, a remodeled bath, and tile flooring. Abundant closet space supports convenient storage.
Outside, fully paved front and rear yards are fenced for privacy and low maintenance, with an exterior gas connection for summer BBQs. A private driveway provides off-street parking for two cars. Built in 1999 with vinyl siding, the home is heated by natural gas forced air. Express and local buses are right outside the loop, with the train a few short blocks away, and nearby parks, schools, and shopping and dining options are close by. Sold as-is.

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
$66,323
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
8.04%
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.
