In a sign that Oregon's business landscape continues to shift away from home-grown ideals, most of the top commercial real estate deals closed so far in 2018 involve out-of-state buyers.

That includes, of the top transactions for which the Business Journal was able to confirm details, 11 California companies that have either entered or solidified their Oregon base.

Another four companies purchasing major Oregon commercial real estate holdings are from Texas.

Just nine of the transactions were closed by Oregon buyers, suggesting that the way locals do business might continue to retreat from the more-provincial and collegial Portland model displayed during the late 20th Century.

The data, which comes from American Cities Business Journals (the Portland Business Journal's parent), reveals the top 32 deals for which the buyers, the property address and the price were obtained. Those 32 transactions were worth an average of $27.5 million, with the high-end set at $1.34 billion.

The Business Journal tracked deals between Jan. 1 and Aug. 31.

Of the properties, 16 are in Portland while seven are in the western suburbs, including Beaverton and Hillsboro.

Five are in Vancouver while Portland's eastern suburbs, including Gresham, count one apiece.
