First off, are you employable? This can matter quite a a bit. If you are employable, you should save cash, and visit the town that you plan on moving to. --This can be made easier if you have acquaintances in this town who can lend you floor/couch space to utilise whilst checking out the town you plan to move to.
I'd like to say also, that if you are collecting disability payments, I have no Idea as to how you would relocate to another town under that scenario, sorry. --You may want to ask around for people in your own country as to how this can best be done. The US Disability System is barely known to me, and the UK version is even more alien to me.
Save up more cash, and check the pricing/availability of apartments, and neighborhoods. In the US, it is best to find a place that rents for at most one third of your monthly post tax income. If you can find something that you like for less than that, get it. You may have to share a place. --If you know people from forums that live where you want to move check into an apartment sharing scenario, but be forewarned, DO NOT DO THIS WITH A GIRL/GUY THAT YOU WANT TO PURSUE A SEXUAL RELATIONSHIP WITH!!!!!! THIS SETS YOU UP FOR A COMPLETE DISASTER IF THE RELATIONSHIP DOESN'T WORK OUT!!!! --YOU WILL WIND UP HOMELESS!!!!
You may have to save up yet more cash to pay a deposit equaling the three times the monthly rent in order to sign a lease. If you have a lack of rental history, what this does is ensure that you have not only your first and last month's rent payed, but also to pay for anything in the apartment that you may destroy or otherwise fuck up. --Be mindful of the neighborhood you want to move to. Anything close to government housing projects ( I think they're called Council Estates in the UK) could potentially be inviting disaster in the form of High Crime Rates, Drugs and Violence.
That being said, though I currently live in The Slums and I can get by quite well with no problems, as nobody really fucks with me anyways.
Once this is accomplished, find a job in the town that you want to live in. One way of doing this is to find a job at a place that has locations in both the town that you currently live in, as well as the town that you want to move to, and transfer over to the new location.
DO NOT just decide that you want to move to a new town and make the rash decision of just moving there w/o cash and knowing nobody, chances are incredibly high that if you do this, you will wind up homeless.
