How many tool kits do home index rewards give?

The kits arrive inside toolboxes, one handed out each time your home index reaches a new level, so you collect them gradually rather than all at once. Twenty-two is the whole supply from this source. Once the last milestone is claimed, raising the score further gives you no more kits.

The home index is not the only place modification kits come from. Homeland level-ups also grant them, alongside cosmetics, extra health and access to crafting systems. If you are short on kits, push both tracks.

Every decor item you buy and place from the build menu for the first time adds Home Index points. That makes the cheapest route to those toolboxes buying inexpensive decorations you have never owned with Bud Tickets, placing them, and selling them back for half price. The linked guide covers that loop and where the Bud Tickets come from.
