DealGauge

Grades any rental deal A to F after every real expense

What it does

Free rental property calculator. Grades any deal A to F, shows cash flow, cash-on-cash, DSCR and cap rate after every real expense, and gives you the highest price you can pay with the binding constraint named. No account, no limit.

Five costs decide whether a rental makes money and none of them are on the listing: vacancy, maintenance, capital expenditure, management and reserves. Put in a price and a rent, or leave ours in place if you do not have a property in mind yet, and in 90 seconds you will know what it really cash flows once all five are counted, and the most you could pay before it stops working. The numbers already loaded are an ordinary looking house at an ordinary looking price. Watch what the grade says about it. No agent, lender or seller pays us. We sell spreadsheets to people who want to go deeper, and that is the entire business. It is why this tool is free to tell you a deal is bad, and fair…from getdealgauge.com

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
