A band I was in a couple years back had a practice space that was part of a large storage complex, like the kind you see on those shows where people buy other people’s delinquent stored property. Anyways these spaces were a bit larger than the one’s you see on those kind of shows and about half of their business was renting rooms to bands on a pay by month basis. Most of them had been acoustically treated (although the bleed through from your neighbors was worse at certain times of day than others) and some had been converted to recording spaces. I saw one with a mic booth and a drum isolation booth.
They had a bulletin board for people looking to share a space or who had a space and were looking for someone to share it with. You could take a chance and google it to see if there’s something like that local to you, rehearsal spaces for rent. They may have a similar bulletin board or something like that as part of their website. Just one idea if you wanted to look into it.
