Do you want a housing calculator that:
- Is completely client-side
- Is easy and straightforward to fill out
- Is comprehensive; we include fields such as expenses you budget for which many calculators do not include
- Is open source
Look no further, because I have a solution for you. I've compiled the formulas that I am using to vet whether or not particular houses are within my means into a webpage that's easily accessible and understandable (and, a little more accurate than ones I've seen online).

I post this somewhat in jest - it is fairly trivial to build something like this, but I hope to share it in case others would like to use it or build upon it for their needs.
