We have a very small budget, so I found all the fixtures on Craig's List. Bath, surround, stool, sink, in wall medicine cabinet for under $250.00
When we needed a new living room suit, sofa, love seat, coffee table, two end tables, small end table and shelves. All from Craig's List, all for under $250.00
Not the colors I would have chosen but I can remedy that as time and money allows.
You can even get stuff for free if you are willing to take it out or pick it up.
People who go the "rent to own" route are just foolish and bad at math.
I have also bought various building materials on Craigslist. Most recently a 32” Fiberglass exterior door for $100. Many times people will order a door and buy the wrong size, swing, etc. You can not return a special order.
This door would be about $300 new.
I have bought hardwood flooring, furniture, tools, snow blowers all on Craigslist. I am currently looking for a used Kubota 29-30 HP, L series compact tractor. Brand new they are $30K. Used $12-19K depending on the hours.
