Having a job lined up prior to the move is probably a VERY GOOD idea...yes there are jobs that pay well....they may be hard to find though.
I completely agree. Two years ago I wanted to move without having a job first (had a BA and some grad school, with more than 2 years of experience in my field). I am very glad I didn't. If I had moved without a job back then, I would have definitely run out of money.
Later, once I was finished with most of my master's (I am finishing it now, and could have done it from anywhere) a friend of my brother's let me use her address on my resume (a very good idea....I found that there is such high competition in Central Florida for jobs, most companies won't deal with an out-of-towner unless the resume is top notch), and I
still had a hard time getting interviews. Even still, jobs in Central Florida, due to the massive influx of qualified candidates who have relocated, tend to pay significantly less and offer less benefits (I did a lot of internet research when contemplating my move).
When I got a job offer with a company in Orlando back in August, I had to turn it down because I wouldn't be able to pay for cost of living here in Buffalo let alone Orlando (I would have been making at least $10-15k more per year here in Buffalo for the same job. I was working on my master's thesis, now had more than 3 years experience, and was offered $26k...I have nearly $100k in student loans
alone, and rents in Orlando are double Buffalo...I wouldn't have been able to pay my bills at all on that salary). I was devastated, and sometimes wish I had taken it, but I do believe I made the right decision.
Another job opp. came and went in January due to health problems, so....what I'm saying is, definitely plan ahead (I planned for 2 years and there were still factors I didn't expect that made an impact, ultimately), and definitely have a job lined up (Currently, I am considering pursuing opportunities with two employers who have offices within 2-3 hours of WDW. That way, I will have job stability before leaving, and the opportunity will be there to move back if I choose so).
Good luck if you ever decide to move!
