Craigslist, yard sales, thrift stores ... all kinds of options for inexpensive furniture. And having no credit is your own damn fault. Get a gas card as soon as you can drive and make your monthly payments religiously. By the time you are in the market for larger ticket items your credit rating should be looking pretty spiff.
Yeah, but that actually takes work.
Depending on one’s budget and location, consignment stores are a good way to find quality furniture at a reasonable cost. In the DFW area, yard/rummage/garage sales in the more affluent neighborhoods are also a good way to find good furniture at an equally good price. If you don’t mind a ding or two, scratch-and-dent places are good for new appliance with minor issues with the finish. The other posters are correct, it just takes some work and a little effort to find something within a person’s price range.
