TallyHome answers the question "how much, right now?".
Your house is the first category TallyHome tackles: how much is your house worth, right now. Have you ever read one of those newspaper articles with a headline like "Sydney House Prices Rise 0.3%" and wondered what that meant for your house? TallyHome answers that question for you, and keeps on answering it, whenever you choose to ask.
We keep track of published house price indexes and use them to value your house right now. You enter the city, state or country that you live in, the most recent valuation (perhaps just the price you paid) and TallyHome figures out the rest.
TallyHome also lets you peek into the future or peer back into the past. Dragging on the top scroller or tapping the right arrow advances into the future. The bottom scroller does the reverse. You can go as far forward or backward as you like... TallyHome probably can't be relied upon if you want to know how much your house will sell for in the year 2500, or equally in 500BC, but knock yourself out in the name of fun.
