Why I built this

I always wanted to invest in property, but the math was killing me. The bookkeeping was killing me. I always wondered if I was truly making money on my deals.

For years I barely managed to record some key events, but I was always stuck in the blue. Properties lose money through so many funnels — vacancy la, broken stuff la, spike electricity la — all of it made me wonder if I was still making money. I mean, I kind of knew, but there was no black and white for me. The gap just kept growing and no one seemed to care.

I wanted to compare — my property against my stock investments, ASB, or even just FD. Not that it would completely change the game, but I just wanted to know. Like how exercising is good for health, but it's good to weigh yourself once in a while and enjoy the numbers.

PropBook started as the tool I needed — one that factors in every cost and shows you the real number.
