my dad was born there and my grandparents lived there many yrs. i hadnt been back there for along time, but when i passed through a few yrs ago now, i thought the older areas at least, looked more run down. there is a substantial crime rate there for a town that size. i always encourage pple moving and especially if they have kids, to check the state website that tracks previous sexual predators. its interesting just how many some small places have.
of course there are some nice areas still, but you have to also think of if the town in general is someplace you want to call home. yes, the sd side has expanded, an escape route...i assume. my relatives lived on the northside, and parts of that are still nice. but overall, would i want to live there? no the job would have to be pretty wonderful for me to consider living there. coming from a big city area with many things to do, you might find it quite dull. yes, omaha is a couple hrs to the south for concerts and more shopping, but still its 2 hrs each way. sioux falls is a much brighter star in the north sky than...sewer city. a name it got from its stockyards odor as you approached the city from the south.
of course you will have to do your own research and draw your own conclusion, but dont jump before being entirely sure. as one person mentioned home sales, if you ended up not liking it and bought a house, you might have some trouble unloading it. best wishes
