They don't say what the strategy is in the comments (duh) but I seem to remember a similar study from years ago saying the optimal strategy was to always buy if you can.
Meta, but one rule I was surprised to learn: if someone doesn't buy a property when they land on it, it is immediately auctioned off by the bank.
Another interesting strategy was to not upgrade to hotels in order to create a housing crisis by using up all the houses
Many people play without the auction rule (hence, they don't even know it exists).

The optimal rule is a little different: don't sit on cash until a housing crisis.
Just like in a real-life business, sitting on cash that could be working for you is a bad idea.
