Someone I know explained to me that in commercial real estate, when it comes to borrowing against a property, the total amount of rent collected is less meaningful then the amount of rent per occupied square foot.
My lower than average rent PSF might reduce the amount the building owner could borrow against the property so better to leave the space vacant and not lower the average.
This was pre-COVID and the great push to WFH. If I came to the building owner now and made the same offer he might not have been insulted.
As it stands, I moved into a nice office space with a great landlord. Electric and gas are included in the rent and the entire building is covered by a generator.
