I’m considering a model with savings and housing. Like @aledinola mentioned, [Chen(2010)](https://github.com/robertdkirkby/Chen2010housing/blob/main/Chen2010.m) can be an example (i.e. generating transition path if downpayment ratio decreases). vfiToolkit will report an [error](https://discourse.vfitoolkit.com/t/olg-transition-path-error/314/10) if the model has more than one state variable.
