Cost of living Index
Moving? There are many Cost of Living Index comparison sites on the internet (perform a Google Search to find them). You should look at 2-3 sites to get a good idea of what a comparable salary in your new location should be. Here are two to start with:
When you use the name of a large city, you are using data for the more expensive downtown area of that city. Using "Dallas" in your research means "downtown Dallas". If you plan on living out in the suburbs, then use suburb names in your research to get useful comparable cost of living data.
Knowing what a comparable salary is to your current situation doesn't mean that a comparable salary will be offered in your new location. Look at job posts for your desired new location to see if the salaries match up with the comparable salary ranges being calculated by these sites.

Finding a job in a different city is very difficult when that city has a lot of local talent for employers to draw upon.
Many people find they have to actually move to the new area in order to "be local" and get interviews. Many employers simply refuse to deal with the hassle of people having to come in from out of town for interviews, then waiting for them to sell a house and/or move all their things here, and adding the risk that their spouse or kids or other relatives will throw a tantrum against the move (or whatever else crazy might happen) that stops the person from actually starting (or staying if they do start).
Time and time and time again we hear our clients say "no out of town candidates - PERIOD!". We find that managers/companies will only consider out-of-town candidates when they are backed into a corner and they must look at non-local talent.
Note: Some potential employers will interview candidates that come into an area on trips, so you may have to schedule multiple trips (long weekends or better yet entire weeks) in your desired area in order to get interest from a hiring manager. Our experience is that hiring managers won't do phone interviews first so that you can then schedule a trip to the area if the phone interview went well (that's too logical, right?). But if we tell them you are going to be local on certain dates and available for interviews, then hiring managers "may" pull the trigger and schedule a face-to-face interview.
Paid relocation usually only happens when the skill set required is very hard to find locally and they are willing to pay for relocation in order to get it.
Bottom line, if a company doesn't have to pay relocation, they won't.
"But I am willing to relocate on my own!" Saying this helps, but you still run into problems where companies just refuse to interview out of town candidates because of the hassle.
