<prompt> Human: Are there any rules of thumb on what to spend on a basement of house worth?We bought a house with an unfinished basement. It is all framed out, has lighting ready, electrical run, insulation, windows, and has plumbing ready for a bathroom. So I think it just needs some drywall, ceiling, finishes, etc. I am trying to come up with a rough budget before we start interviewing people to do the work.Any ideas? It should be cheaper with the above work already done correct? The house is about 500k basement is around 1200 square feet.  <response>: DrywallOddly enough, not dependent on your square footage. This will be determined by how many linear feet of wall you have in your basement. If its just a couple wide-open rooms, itll be cheaper than several smaller rooms.Electrical - if its already stubbed out - will be determined by how many fixtures and how nice they are.The big items are going to be bathroomkitchen and flooring. Also whether you opt to DIY it or have others do it.What you need to do - absolutely - is get everything documented. People blow their budgets because they failed to account for everything. For drywall, youre pricing out hanging, plaster, sanding, priming, painting, doing cutouts, and depending on where youre at, moisture barrier in the basement. For the bathroom, youre pricing out the vanity, sink, faucet, toilet, shower, tub, shower fixture, light fixture, tile flooring, and you probably want greenboard drywall.Point being, figure out what you want it to look like, and write down extensive notes. The price will be much less of a surprise, and contractors wont have to guess.
