Republican U.S. Senate candidate Dino Rossi earned at least $380,000 last year, boosted by real-estate deals he made working at an Everett firm, according to his personal financial-disclosure report filed Friday.

His income included $16,000 in speaking fees for a series of real-estate 

seminars attacked by Democrats because they included advice on how to profit from buying foreclosed homes.

In all, Rossi owns property and other investments worth between $4,395,000 and $15 million, his filing said.

A former state senator from Sammamish, Rossi has a long background in commercial real estate, and he frequently talks about buying his first apartment building when he was 25.

In late 2008, after losing his second gubernatorial bid to Gov. Chris Gregoire, Rossi joined Coast Equity Partners as a principal in charge of property acquisitions and investor relations.

Rossi's exact finances are impossible to determine because the financial-disclosure forms that all candidates must file only require them to check boxes representing broad ranges of income. For example, Rossi's biggest slice of income from Coast Equity was listed at "between" $100,001 and $1 million.

Rossi previously was granted an extension from regular filing deadlines for the financial-disclosure forms after entering the campaign in late May.

He would not further clarify his finances, saying he'd complied with reporting requirements. He pledged to place most of his real-estate investments in a blind trust if elected, to avoid any appearance of conflict of interest.

His total income last year was listed as between $380,000 and $1.5 million, according to the filing with the Secretary of the Senate. In 2008, when he last ran for governor, he reported income of at least $255,000.

Rossi made the bulk of his money from rent on several apartment and medical office buildings. Some buildings he has owned for years, while he received ownership interest in others through his work for Coast Equity.

His biggest asset was Hartford Court LLC, which owns apartments in Lake Stevens. It was valued at between $1 million and $5 million.

Incumbent Democratic Sen. Patty Murray's finances are comparatively simple, according to her latest filing in May. Read more of   click here.
