I’ve been thinking about building a “what are my mortgage options” type of tool for this reason. I’m a banking attorney who can code enough to be dangerous but I worry there are too many variables for my self-taught coding skills to handle. If anyone with a complementary skill set would be interested in building it with me (free, open source, no data harvesting, etc.) I think it could be useful to a lot of people. Edit: I’m decently knowledgeable with MEAN/MERN, Django, and Swift. I’m less practiced but still (mostly) capable with Rails and Go. SQL and I are frenemies but I’m working on it.
