Section 8 process in Columbus

[Sean Haran]

Hello! I am looking into renting out a duplex in Columbus through section 8. Would love to hear people’s advice/opinions/experiences. I’m rehabbing the duplex before renting it out so I already know I’ll have to make sure everything is up to section 8 specific standards. 
My main questions would be: how long does the entire process take from applying to actually having possible tenants to start picking from, and how do they determine exact amount for rent (the amounts listed on the housing authority site seem way higher than market rent, I’m wondering if I will actually get those numbers or not)

any other general tips or advice is also appreciated!
