Suggestions for modeling large flex properties efficiently

Hey all,

I’m looking for recommendations on finding the right model for underwriting industrial flex acquisitions. There are plenty of quick models out there, but finding one that allows me to efficiently input a large number of tenants has proven challenging.

Currently, I’m using a Break Into CRE model that I scaled up to 70 tenants. However, once I get past roughly 20 tenants, the model becomes very slow and I start running into more issues.

My main issue with very simple models is the lack of ability to efficiently model second-generation leases and tenant rollover.

I might be looking for a unicorn here, but unfortunately I don’t have the ability or access to use ARGUS.
