Start with the actual unit, not the architectural label. Lowell's architectural guide describes varied and sometimes mixed building styles. National Park Service material documents the history of mill conversions, including tall windows and open interiors; its older rents, businesses and redevelopment proposals are not current housing offers.
In a converted building, examine the private unit and the shared route separately: entry control, elevator dimensions and reliability, corridor turns, loading access, sound transmission, heating and cooling, and where deliveries wait. Large windows and high ceilings do not establish an easy furniture route or low energy bills. In an older house or multi-family property, inspect the porch, vestibule, stair landing, handrails, laundry and storage responsibilities.
Compare written costs in three groups. First, the recurring housing commitment: rent or mortgage, applicable taxes or association charges, insurance and renewal terms. Second, the services actually included or separately paid: heat, electricity, water, internet, laundry and parking. Third, one-time costs: deposits, setup, moving, storage and any required building fees. Keep an annual or one-time charge separate from a monthly bill. Two advertised prices are not comparable until their inclusions and usable space match.
Walk your largest existing piece from the legal unloading position to its intended room. Measure the item, clear door openings and the useful depth of each landing with doors and handrails in place. Confirm permitted disassembly and who can authorize it. Record repairs, storage permissions, meter responsibilities and promised parking in the agreement. For a lower room or basement, ask about previous water entry and what may actually be stored there.
