The mortgage on a $250,000 home right now is $1200 a month.  With good credit history you can usually qualify for a loan up to around 35% of your gross monthly salary.  That would mean you would have to be making approximately $3500 a month - or $42,000 a year.  In 2013 the average per capita income on Whidbey Island was about $43,000.  Per Capita = each person.

So yes......that housing price range is the affordable price range for one income families - and very affordable for two income families.
