Commercial Property with Residential Mortgage

[Benjamin Benomar]

Is it common for mortgages to have restrictions on another use on the land?

A little background... my partner purchased a quadplex on commercial c-3 zoning in historic neighborhood, Atlanta, GA using a residential loan. The property is on a strip of bars and restaurants. We want to potential leverage the extra land next to the building to develop a bar/restaurant.  Does having a residential mortgage impact the ability do business? Are mortgages tied to the building or land?

Thanks in advanced for any insight or advice.
