Good that you mention that - and setting up some basic acoustic acoustic treatment is neither costly nor time-consuming.
I'm not a pro and only doing music stuff for fun. But I would advise against monitor speakers if the OP doesn't have a proper mixing room. IMO the money would be better spent on a pair of good studio headphones in that case.
I bought some basotect scraps on eBay, some plywood panels and cheap cloth and made two pairs of DIY absorbers that do a pretty good job - the whole thing cost about 50 bucks and an afternoon including fetching the material.
