## Why I built this

I have been obsessed with property since I was a child, and it started with a board game. The little houses, the rent you collected when someone landed on your square, the gamble of when to buy and when to hold. It taught me, years before I understood it, that property is really a game of cash flow, timing and nerve.

I have spent most of the last fifteen years living that out for real. I listed my first flat in Istanbul in 2010. I built Erasmusinn, a student-housing marketplace that grew to around ten thousand rooms. I bootstrapped Oval Experiences and ran about sixty short-let apartments, where I learned the hard way how quickly an operation falls over when it depends on people remembering everything. With Fullog I took the same playbook into fulfilment, arbitraging space and running the logistics on top of it. Today I am building Cendra, putting AI to work on the messy, human side of running rentals.

Rental Rush is all of that, distilled into a board game. Every mechanic comes from something I have actually felt: the void period in low season, the owner who wants paying on time, the licence that drags on for months, the building lease that bleeds you before it earns a penny. It is a small love letter to the operators who keep the lights on, and an experiment in how much real operating intuition a simple game can carry.
