Rental Gain is a pre-launch opportunity intelligence product for small rental investors working 2-4 unit buildings in Washington County and Fond du Lac County, Wisconsin. It screens candidate properties on modeled cash flow rather than asking price alone, and shows every assumption behind the number.
The portal currently displays hand-authored demo records: no live listing feed, alert delivery, account system or billing is connected yet. Nothing here promises a return. The browser-based cash-flow calculator is fully usable today and runs entirely on your device with no account required.
