Well, just a few things that come to mind: * Speaking the language -- in some places they don't speak much English, and certainly don't do official paperwork in it. * Local laws * Safety * How much stuff you need is going to be nearby * Internet access * Local culture * Employment * Friends and family Like, I don't know much about Serbia (just looked up where housing is cheap), but from what I hear I could get a pretty good deal if I moved to Russia -- they're desperate for tech workers and offering some very good perks regarding mortgages and so on. But on the other hand, is living in Russia that good of a deal right now? I don't think so. They've got a bad government, slow and very restricted internet access, a not terribly pleasant society overall in my impression, and the economy is circling the drain due to all the sanctions.
