You could definitely find something similar to what you are renting now for around the same price here.
There are a couple things about Birch Bay though that are not so great....but they are tolerable:
(1). At certain times of the year more so than others...there is an absolutely horrible smell along a stretch of the waterfront through Birch Bay......it could be something in the saltwater bay...(it is quite shallow) like in the seaweed and sometimes the beach is closed to shellfish harvesting due to "Red Tide" which is toxic and NOT good to swim in either..."swimmers itch."
GREAT BAY to LOOK out across though....makes me really wish I had a boat, personally! But I won't swim in it....have waded in the bay before but not for long.
(2). 2 miles south of Birch Bay is a large oil refinery....and if you drive past it....it stinks too...or if the wind is blowing from the direction of it....its noticeable....but fortunately.....NOT too often.
Overall.....it is definitely a great little area and quite scenic!
Just be prepared for very long, dark, gray, rainy/drizzle season....ALL winter long....( I would imagine Alaska can relate?)...very early darkness too a lot of drip, drip, drip.....oh yeah....and an occasional...awesome windstorm to livin things up...(sometimes an all day/night steady wind of about 50 mph and gusts over 75 or 80. These are NOT that frequent and generally they occur in October/November and maybe February/March.
Last November was BAD!!!!
Within 4 weeks we had 2 MAJOR windstorms (gusts to 90 mph).....flooding rains before and after the windstorms....then....topped it all off with an 18 inch SNOWSTORM......ALL BEFORE Thanksgiving!
November can be a CRAZY month!!!
BACK to SWIMMING:
PLENTY of other places to swim that have much nicer and cleaner conditions....namely a couple lakes in/near Bellingham.....Lake Padden is great for swimming....Lake Whatcom is ok too....'cept for some bird feathers in the water sometimes....and then Lake Samish....just south of Bellingham....clear water but kinda cold generally.
Lake Padden is my personal fav. and it has a grass beach that a LOT of people sunbathe on....especially when we get a brief but HOT...heat wave.
BTW...In the summer it can be 15 or 20 degrees cooler in Birch Bay than it is only 10 or 15 miles east...(inland)!!
It gets HOT in Lynden and most homes here do not have AC.
(Somethin to think about)....but heat waves are generally short-lasting....generally....except last summer...it was HOT and NO rain for 3 months! RARE here!!!
I'm not much for swimming in the saltwater here though......Hawaii was great for that....but not here, IMO.
Larrabee State Park south of B'Ham and Chuckanut Drive to get there IS GORGEOUS!!!! More so in the fall when the leaves are at their peak colors!
WINTER SPORTS:
Mt. Baker Ski Area is great for snowboarding/skiing.....BUT it is about an hour to hour and/half drive east and in the winter....there can be some really treacherous roads in the Cascades and chains ARE required more often than not.
Whistler/Blackcomb Ski Resort up in British Columbia Canada is about a 2 1/2 hour drive north....(depending on traffic in the Vancouver area as well as the border crossing wait time)....BUT it IS the BIGGEST and by far, the SWEETEST resort in ALL of North America!

EVERYTHING you can imagine in winter recreation is available.....even sleigh rides and intertube rentals for rushing down the mountain...also helicopter (heli-skiing)....high altitude out-of-bounds extreme skiing/boarding.....and it...and Vancouver...will host the 2010 Winter Olympics!
Gotta LOVE the GREAT PACIFIC NORTHWEST!!

Hope ALL this info. helps ya.
