Main Street McMinnville is looking for a new home after having to pay $5,280 in back rent to the Chamber of Commerce.What was once a complimentary stay in the basement of the Chamber of Commerce building in downtown McMinnville will now cost the nonprofit organization in monthly rent. The new expenditure, the Main Street McMinnville board fears, could stretch its budget. That fear led to discussions MSM may want to seek a new home.The move to look at other locations comes after the resignation of co-director Brook Holmes and the appointment of interim executive director Paige Chastain.
