4 million bells is a decent sum of money, but it all depends on why you’re considering selling your town in the first place. if it’s because you don’t like your town layout or name, your character’s name, where you’ve put certain permanent pwps (ex. the roost) or because of anything about your town you can’t change, i say go for it. of course, you’ll lose your villagers, all the progress you’ve made, any badges you’ve earned and any items/clothing you’ve obtained, but that can all be replaced if having a new town is something you really want.
however, if it’s because of something like you just want a save file with more bells, you can always earn more by catching rare beetles and fish on tortimer’s island and selling them at re-tail, selling stuff in general or even buying bells from other players in the
re-tail trading board on here. i know people occasionally give bells away for free as well.
the choice is entirely yours, though; no one can tell you what to do with your town. you just have to ask yourself why you want to sell it, and if doing so would be worth having to start all over. good luck!
