Rent Increase Calculator — reverse calculation mode

The Rent Increase Calculator can now find the implied increase percentage from current and proposed rent, or still calculate new rent from a known percentage. Same page, same URL.

Added

  • I know the new rent mode: current rent + new rent → increase %, monthly increase, and extra cost over the selected months

Improved

  • Clearer mode choice so percentage and new-rent inputs are not shown at the same time
