Income property real-estate evaluations, lightning quick and customized to your investing style.

Lightning Pro Forma makes it easy to quickly evaluate any real property for investment purposes. You get the information you need to make an informed decision without having to fill in countless fields of data every time. You just provide the purchase price and the expected rent and Lightning Pro Forma takes care of the rest.

And if you want to change the basic assumptions for the evaluation, you can do that too. You can also maintain as many different variations as you need so you can quickly flip between different financing assumptions or different rental markets.
