Lease Rec for Renting out Garage Space-Chicago

[Chelsea Pfeiffer]

Hi BP community, 

Curious to know how others go about renting out their garage spaces here in Chicago. I have some turnover and the incoming tenants don't need the open space in the garage, so I am looking to rent it out. I am used to the garage being wrapped into the Chicago lease, but since the space will now be independent of a unit rental what lease(s) would you recommend I utilize? I was looking into Curbflip, Spothero, etc. but am not too keen on the commission the sites impose for using their services. 

Kind regards,

Chelsea
