The Long Dollar

What one subsidy dollar does over thirty years

What this tool does

A subsidy that buys down one home can be written two ways. It can be retained, staying with the home and holding it affordable for the next buyer and the one after that. Or it can be repayable, returning to the program when the owner sells, to be spent again at whatever the market costs by then.

This model follows one dollar down both paths for thirty years and reports what each one cost to hold a home affordable over that period. It sets renting beside them both, so the picture is complete for funders, homeowners and the community. Enter your market below. Nothing is assumed about you that you cannot change.

The model runs entirely in your browser. When your numbers are set, Create exhibit produces a four-page document with your market and your name on it, ready to print or hand to a funder.
