A local builder known for their contributions to charity auctioned dozens more homes over the weekend.

Buena Vista Custom Homes offered 52 of its new houses for auction at the Ambridge event center in Portland Saturday.

The 36 homes that sold went for a combined $10 million.

Many who won bidding wars paid thousands less than the home's appraised value.

“It wasn't as hard as we thought it was going to be, you just have to pre-qualify, and hope that nobody bids higher than you,” new homeowner Sandy Blackburn said.

In December, the company auctioned off 141 homes for more than $65 million.

It's believed to be the largest two-day real estate sale by one seller in Oregon history.

Homes offered at auction ranged from 1,113 to 5,073 square feet and were located in some of the areas of highest demand around the Portland metropolitan area.

Additionally, 29 homes were also included from the Bend, Oregon market. Homes sold from as low as $195,000 for a 3 bedroom 2 and a half bath home in Sandy, Oregon to $510,000 for a 5,073 4 bedroom 3 bath home in the Shadow Ridge subdivision in Happy Valley, Oregon.

Buena Vista also donated over $250,000 from the event to area charities as part of Pollock’s “Profit Partners” program. The program donates a portion of each home sold, regardless of price, to 19 area charities.
