Charles Burnett, CCIM is the Principal of Sound Property Group, a Puget Sound real estate team specializing in multifamily and investment properties.
A Seattle-area native with more than two decades of real estate experience, Charles has built his career around helping multifamily owners and investors make better decisions about their properties. From 2015 through 2025, Charles ranked #1 in Washington State for the most multifamily properties sold.
Charles specializes in the valuation, marketing, negotiation, and sale of duplexes, triplexes, fourplexes, apartment buildings, and other investment properties throughout the greater Puget Sound region. His experience spans hundreds of multifamily transactions and gives his clients a level of market knowledge that comes from actually negotiating and closing deals—not simply analyzing them.
As a Certified Commercial Investment Member (CCIM), Charles combines advanced investment analysis with hands-on transaction experience. He helps owners evaluate more than just a potential sales price, including property performance, return on equity, market timing, 1031 exchanges, seller financing, and other strategies that can affect the ultimate return on their investment.
Charles believes every property and every owner's situation is different. Whether a client is ready to sell today, considering an exit several years from now, looking to complete a 1031 exchange, or simply wants an accurate understanding of their property's value, his goal is to provide straightforward advice and a strategy built around the client's objectives.
Through Sound Property Group and SoundMultiFamily.com, Charles provides multifamily owners with specialized market expertise, extensive buyer exposure, strategic marketing, and experienced representation from initial valuation through closing.

Most Multi-Family Income Properties for sale in Seattle are fully rented and are listed as "drive by only, subject to inspection". This is because the sellers do not wish to disturb the tenants for a home showing unless they have an acceptable offer in hand. While this would be considered unusual for a single-family home sale, it is the standard case for income properties.
Offers Subject to Interior Viewing
When conducting an investment property search in Seattle and throughout the Puget Sound area, it is important to be aware of a property's classification. This is based on factors such as location and property condition (usually A, B, C, or D). For more info on this topic:

Multi-Family Properties in Seattle are divided into two categories: Residential and Commercial. Residential Income Property is defined as a multi-family home with up to four separate living units (duplex, triplex and 4-plex/quadraplex). These units may be within a single structure or as separate structures on the same lot. A Seattle multi-family property with five or more units is considered a Commercial Property. Living spaces may be stacked, built side-by-side, or separated by a firewall. Income Properties allow for profitable gain when renting out individual units as the property appreciates. Properties zoned both Residential and Commercial present an opportunity for investors to combine their home, business and rental spaces.
