Yeah I'm still here (on the forum lol) but moved back home to Seattle. Never had a problem with anyone on here and still drop by the SC section to contribute from time to time.
Moved home in December and for me at least it was a good decision. Weather is cold rainy and overcast (which I like) but have taken a few months off work to snowmobile, work on the house, visit family
To the OP: Don't be fooled thinking that the cost of living is soooo cheap that you are going to live like a king if you move to Myrtle beach lol Right now I am paying right around $3.85 in North Seattle for regular gas where it appears to be right around $3.50 in Myrtle Beach. Not a significant difference especially considering I drove much further/more to get to stuff living in MB area as it is spread out. My car insurance was actually more expensive in SC than in WA.
Other things are not much different either. My wife said food in grocery stores seemed slightly more expensive in MB vs Seattle and going out to eat was about the same. Seattle sales tax is 9.5% while it is 9% in Myrle Beach, in SC though you do have an income tax which you dont have in WA.
Going out to movies is cheaper in MB, $8-9.00 vs $10-11:00.....but $2.00 isn't going to break the bank. Other things like clothing etc. I would say is a wash as far as price goes, didnt notice any difference other than styles are behind the times there lol Didn't know they still made jean shorts until I moved to MB
As far as your job goes dont move out there until you have one. If you land a teaching job (if) it wont be "half" of what you are making but it will be less. Also not sure if working in the teachers union is important to you but if it is, they dont exist in SC.
I moved to SC already having a job but my job pays off of a flat fee schedule so I make the same amount as someone living in NYC, Seattle etc. If it was baised on pay in SC I would not have moved. My wife moved out to SC 6 months after I got here and left 6 months prior to me leaving. For the year that she was here she could not find (what we considered) a decent paying job. She has a bachelors degree and 5 years related job experience in her field. The few jobs she was offered out here were in the $24K a year range while she left a job making almost $60K a year. She decided to take a nanny job and hang out at the beach with the kids instead lol
Housing is cheaper which is nice. Looking on Zillow average home prices are just above $100K in Myrtle beach. Not sure where in Seattle you live but in Ballard average home prices are right around $400K - $450K. Rent however seems to be not much less compared to Seattle area. Where I was living in Pawleys Island you can expect to pay between $1,200 to $1,800 for a nice place fairly close to the water. In relation to that my parents rent out a nice older home in Kenmore up above lake washington in a nice neighborhood for $1,700 a month. I would think in Seattle area you should be able to rent something pretty decent for between $1,500 and $2,500 a month. While MB area seems to be less it does not seem significantly less to me but every little bit helps.
Honestly it just depends on what you want. If MB is your dream area you will make it work. If you think you are going to move to a beach paridise and make what you are in WA and pay pennies on the dollar for everything else you will be in for a reality check lol Hopefully this post helps out. I have tried to leave my opinion out and just give you some facts to go off of.
