commercial lease leverage

[Jeff D.]

The lease on a commercial space I have rented for 7 yrs is up for renewal.   Problem is 6 months ago new building owner took over.    He is taking full advantage.   Increasing rent by 20%.    I know I have the leverage of threatening to rent elsewhere,  problem is,  with my biz (laundromat) - elsewhere is a big expensive ordeal that isn't feasible.       So other than bluffing and threatening to leave (even though i really can't),   what other leverage do i have?
