Looking for landlord tenant advice for state of Ohio.?

We have been living in a duplex for a little over a year and have had nothing but problems since we moved in. We tired getting out of our lease but had to give sixty days notice and didn't know that so we are stuck till April. We found out this past week that our landlord is now renting the place next door to someone who has a pet. We moved here in the first place because it was pet free and my husband is allergic to animals. Is there anything we can do? We really just want out of our lease it's been a horrible mess the whole time we have lived here. Our garage floods and it was promised to be fixed and still hasn't. Also our lease was never notarized and I found case law in Ohio stating that a lease that has an automatic renewal clause like ours has to be signed in front of a notary. I have contacted a lawyer before but my husband is the only one working and we don't have the money to obtain one. Any help would be appreciated.
