Ok, so I am starting a site that has a bunch of sub-directories (37 to be exact). I am planning on making each of these sub-directories rank on the first page of google and renting them out (I have a proven method for the actual client getting part, so I don't need help on that.) All the subdirectories say the same thing right now until its rented out because each subdomain acts like a profile for whoever is renting out that site so they say things like "this is where you profile would go" blah blah etc. The only real difference is the city name and other small things like that. My question is, will having all these subdomains say the same thing be bad for rankings? Like will it trigger spam for Google or duplicate content or something? Thanks in advance for help!
