Only briefly mentioned above was a dark room. Not 'sort-of dark', not 'nearly dark', not 'I can barely see' dark, either. But 100% dark...can't see your hand 2" in front of your face dark.
While building a darkroom in the basement is an option, just the studs and plywood would be in the hundreds of dollars. A better solution is a pre-existing room without windows somewhere in the house. Then all you need to do is block off any light coming around the door. Note that most interior doors are a loose-enough fit that light comes around all 4 sides, especially the bottom, due to allowance for carpeting, etc. And before you 'set up shop' in a nice-sized walk-in closet, should one be available, carefully remove any clothing or anything else that might be accidentally damaged if splashed with chemicals or might absorb the odors given off by the chemicals. If it were my parents walk in closet, I'd remove EVERYTHING first, carefully hanging what needs to be hung up in other closets.
Also not mentioned was printing. While contact prints made directly from the film are OK to look at, they are film size, eg 36mmx24mm.
An alternative is to scan the negatives into your computer. But you'll need a slide and negative capable scanner to start with. Those scanners typically have a separate film-holder tray to hold the negatives flat and have a light in the lid that shows through the slides and negatives to illuminate the scanner sensor.
Or, you can get an enlarger and table large enough to hold your largest print size and the enlarger itself. Add in trays of developer, etc for the prints. For what it's worth, there's many amateur photographers selling their darkroom equipment for a song these days. Watch Craigslist or
ebay, or even check out the used equipment sources such as
Adorama,
B&H, and
KEH.
Keep your eyes open and find a photography club in the area. There may even be one at the local university campus.
