it's hard to scout an area if you don't live locally, it costs money to get there, potentially somewhere to sleep overnight if it's a long trip. Then the same for the job interview. And possibly several trips for the house as well.
Then even if you find the job, the house, and other practicalities you've still got to find the money to move!
tbh unless the job was going to be well paid I can't see many people wanting to do that even if they could source the money from somewheere.
I had to take out a social fund loan just to help me move almost 2 years ago - I'm still paying it off. Will be until the middle of next year.
I can also agree with Dooin on the bus fares and timetables not fitting with work.
Last year exH applied for a job in the next town, he was offered it. FAB you'd think.
Except we didn't have a car, the only way to get a bus there in the mornings was to arrive 1 before he started work with the journey taking 1 1/2hrs (and the office wasn't open before then), and then the bus back he would have had to wait almost 2 hours for the bus - for the same 1 1/2hr journey back, for minimum wage, and a bus fare of £10 return a day.
6hrs a day travelling/waiting (and no-where to wait either other than at the bus stop) for minimum wage.
After much number crunching and talking he didn't take it(which in hindsight was just as well as he was actually really rather ill at the time but we didn't know it then).
I have a close friend whose daughter works in a nursery on the same industrial estate. Thankfully the DD has just passed her driving test, as he mum was having to drive her over to work in th emornings , before driving back to our town and to her own job, and then back to pick the DD up after work. Different working hours to exH's job but the bus times and fares just made it impossible to do otherwise.
