What we do

Sell a commercial propertyPricing, marketing, buyer screening, escrow

We price from recent comparable sales and the property's income (net operating income and cap rate), prepare the offering package, market it to qualified buyers and brokers, and manage the transaction through escrow. We tell you up front what the commission is and put it in the listing agreement.

Talk about selling

Buy or investRetail, office, industrial, mixed-use, 5+ units

We help you define what you can buy and why: location, zoning, tenants in place, lease terms, deferred maintenance and financing. We run the numbers with you before you write an offer and coordinate inspections, environmental reports and lender requirements during escrow.
