I do all of my recordings in a totally untreated room. My approach was to get good near field monitors, a good audio interface, and a DAW. By good I do not mean expensive. You can get the good monitors and audio interface for a reasonable price. Any DAW will do and if you a PC and you have or get Band-in-a-Box it comes with a DAW.

I record my acoustic and electric guitars directly into my DAW: Amp syms have come a long way and can sound really good. My acoustic guitars are plugged directly into my DAW via either the built in electrics or a tuning piezo pickup. I can get virtually any guitar sound I want using effects in my DAW.

I use the following for my dynamic and condenser mics, again I don't have expensive mics:

Also note that there are lots of good free effects and amp syms available as well as some very good inexpensive ones.

Also as been mentioned using Band-in-a-Box (BiaB) can produce professional sounding backing tracks, even at the lowest price point as the engine is identical in all versions of BiaB. The difference in the BiaB versions is the amount of RealTracks, Realdrums, and styles.

I started out and currently am recording with low to middle of the road priced equipment, software, and guitars. YMMV

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
