Factories reduced production of everything during COVID getting ready for a recession type environment that never appeared. 

Even your "US" brands have factories and get parts from other countries. 

The other factor is getting a builder (unless you already have one lined up). 

The only " what if factor " is the annual insurance.

We also have long term tenants because of our factory jobs here.

The other huge factor is your CoC return on that money, so dependent on how much you're putting down.
