Investment Insights

Based on property information with market context.

This two-story commercial building offers 2,460 square feet of flexible space designed to accommodate office, retail, or service uses. The layout includes multiple private rooms and meeting areas, along with a full kitchen for daily operations. A balcony overlooks Main Street, adding an additional indoor-outdoor feel to the space. Parking is available at the rear with privacy, supported by street parking in front.

The property is located in Historic Downtown Humble with prominent frontage along E Main Street. The setting provides direct street visibility and convenient access for customers and staff. It is positioned minutes from FM 1960, I-69/US 59, and Beltway 8, with approximately 15 minutes to George Bush Intercontinental Airport.

For an owner-user or investor, the building’s mix of private rooms, meeting space, and kitchen supports a range of small-business concepts that may benefit from both street-facing presence and functional interior separation. Its historic character and downtown positioning can also support mixed-use strategies where a primary business space and secondary uses can share the same structure.

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
$32,222
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
7.94%
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.
