Get out of lease early

Hi, im new to this, so please bear with me.

i have 18months left on my commercial lease, things are really bad financially and i want out.
i have been told that even though my house was not put up as collaterel
when i signed the lease, the landlord can force me if he wanted to, to take a loan against my house to pay the outstanding 18 months of rent that there would be if i left early.
Is this true.?
