Benchmarks to Hit: Portable to Permanent

Portable vs. Permanent. Are there benchmarks/metrics you should look for to move to permanent? Is there a cap on what you should pay for portable?

We never let the building cost exceed 35% of the budget for a campus. Create a ceiling and do not let yourself exceed it. 
We don’t have set benchmarks to determine when a campus should become permanent. Sometimes circumstances let us stay portable longer. The GrowLeader Team would be happy to connect and discuss your specific situation.
