A 91-unit apartment complex near Costco's Issaquah headquarters has traded hands for $37 million, marking one of the more notable Eastside multifamily deals of the year. Seattle-based Timberlane Partners acquired Vista Ridge Apartments, an eight-building garden-style property at 201 Mountain Park Blvd. SW, from longtime owner Belkorp Holdings.
The sale, reported by CoStar, closed out nearly 30 years of ownership for Belkorp, which originally purchased the complex in 1996 for roughly $7.3 million, according to Multi-Housing News. That works out to more than a fivefold increase in value by the time of the August sale — a striking illustration of how much Eastside multifamily real estate has appreciated since the property was completed in 1992.
The deal broke down to $406,593 per unit, a figure that actually came in slightly below East King County's Q2 2026 submarket average of $432,000 per unit, the outlet's report notes. Commercial brokerages have observed growing willingness among property owners to negotiate on price as higher interest rates reshape the multifamily buying landscape, creating openings for private capital to move in on assets like Vista Ridge.
How the Purchase Was Financed
Timberlane financed the bulk of the acquisition with debt, according to Commercial Observer, taking out a $27 million first-mortgage loan — about 73 percent of the purchase price — from Mesa West Capital, an investment platform within Morgan Stanley Investment Management, through its Mesa West Real Estate Income Fund VI Holdings. That debt facility is expected to cover both the purchase itself and the renovations Timberlane has planned for the property.
King County tax records placed Vista Ridge's 2026 assessed value at about $31.4 million, meaning Timberlane paid nearly an 18 percent premium over the county's valuation. The transaction generated approximately $1.26 million in state and local excise taxes, and the deed transfer was recorded on August 27, with $36.95 million of the total attributed strictly to real property, per the same tax filing.
Renovation Plans as Leases Expire
Vista Ridge is running at 97.8 percent occupancy as of August, the outlet's report states, with most of its interior layouts remaining in near-original condition from their 1992 build. Timberlane intends to modernize units one at a time as individual tenant leases roll over, adding quartz countertops, stainless steel appliances, and updated plumbing and lighting fixtures.
The property sits along the Interstate 90 corridor about 17 miles east of downtown Seattle, drawing renters connected to major nearby employers including Costco Wholesale's corporate headquarters, Microsoft, and T-Mobile. The submarket combines strong demographic demand with minimal new housing construction, conditions that have made existing apartment stock especially valuable to buyers like Timberlane.
Part of a Broader Acquisition Push
Vista Ridge is the third property Timberlane has acquired through its Timberlane Acquisition Fund II, following the fund's earlier purchases of the 532-unit Jackson Apartments in Seattle and Wonderland Creek Townhomes in Boulder, Colorado, according to the Puget Sound Business Journal. Fund II is the firm's second closed-end private investment vehicle.
The Jackson Apartments deal was itself notable: in December 2025, Timberlane partnered with PCCP to acquire the LEED Platinum, 532-unit property in Seattle's Central District for $173 million from Vulcan Real Estate, a transaction that ranked as the largest in the firm's history at roughly $325,187 per unit, per Daily Journal of Commerce. Founded in 2011 by Dave Enslow and John Chaffetz, Timberlane has offices in Seattle and Los Angeles and active local development underway, including 300 units planned in Ballard and 189 units planned in Fremont.
A Tight Housing Market Around Issaquah
The Vista Ridge sale lands as Issaquah considers additional housing options. In July 2026, a proposal surfaced to convert two vacant office buildings near Costco into 262 residential apartments, a project Hoodline previously reported. The proposal would add apartments through an office conversion, while Timberlane plans value-add renovations at Vista Ridge.
