Great visualizations and simple clean presentation. I tried to use a number of these simple tools to evaluate investment properties but they were usually too high level. I ended up building my own very detailed spreadsheet where the inputs can be tailored very specifically. I know it's not "software" in the HN since, but I made the Google Sheet available online [0] here if any one wants to use it. Note that this is a shared demo so your data will be overwritten by other users.
