We just moved, and actually bought a few new things picked specially for the exact space - quite different feeling than our usual approach of arranging and rearranging our rummage sale finds
. And we just got new sheets that are *not* the cheapest thing at Walmart - it's rather nice.
Here's my rough estimates, based on a bit of googling:
a new bed: 200-600 (ikea level), 1000-2000 for solid wood
two nightstands: 50-100ea (ikea level), 400+ea (solid wood)
a new dresser: 100-400 (ikea-level), 900-2000 for solid wood
lighting: 100-150 for ceiling light fixture, 50 for two bedside lamps. 50-100 for a floor/table lamp
sheets/pillowcases: 50-200 (depends on how nice)
pillows: 50
comforter or duvet: 200-300
paint: 50-100
wall decor,
bench: 100-200 (ikea-level), 500-1000+ (solid wood)
etc
So I'd say $2000-2500 at the lower end, and $5000-6000 at the upper end (of course, that's my upper end - I'm sure you could spend a ton more if you wanted).
Although, mostly, this reminds me why I'm largely happy with the garage sale finds our parents found for us when we married
. It was really hard for me to drop $5k on setting up our new house (over half on new carpet), though we had it.
