Investment Insights
Based on property information with market context.
A 5,600 SF professional office building in owner-occupied condition, offering views of Sylvan Lake. The property is currently configured into four office suites plus a large garage/warehouse area, supporting both office use and storage or light operational needs. Owners may remain as tenants or vacate, and floor plans are available for review.
Located at 813 Main St in Avon-by-the-Sea, the site sits within the General Commercial Zone and is part of the North End Redevelopment Plan. The building provides visibility and easy access to major arteries, with parking on site for 10 cars and convenient street parking.
This configuration can be a practical fit for professional operators looking for multiple office spaces under one roof while retaining a substantial garage/warehouse component for equipment, storage, or back-of-house functions. Buyers may also find value in the flexibility to occupy as-is with the current suite layout, or to reconfigure based on their tenant or operational requirements, using the available floor plans as a starting point.

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
$91,857
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
5.25%
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.
