Super-fancy house cost calculator

This calculator is designed to figure the total cost of buying, owning, and then selling a house.  See the accompanying blog post for background and excessive verbiage about the parameters and output columns.

As you'll see, once you've chosen some values and hit the button, it will pop up a new window with the detailed results. Also on that window will be a link to the calculator that feeds it the values you used, so that it will prefill with those instead of the defaults (good for bookmarking, or trying different variations).  Also note that you can make the table more readable by clicking on column labels to hide the columns you're not interested in seeing.

UPDATE: the javascript for this was being hosted on Google Drive, which stopped supporting static hosting. In the meantime, I made some small improvements and put a version up on GitHub, so head to klaash.github.io/house-calculator to give it a spin.
