Additionally, installing a makeup air system along with a ducted vent hood seems impractical and costly.I've considered alternative options such as a recirculating vent hood, but I'm concerned about its effectiveness in removing grease and smoke. 

Great information you are sharing.

The text you shared from your contract is very clear that you agreed to renew the lease, you agreed to give 60 days notice of termination, and you agreed to pay the fees for the remainder of the year.Those are bad terms, but you agreed to them.

My concern is; it is a more rural property and comps might be hard to come by.

Hey Ruth, I've got a map of Cincinnati I'd be happy to share.

I communicated with them, shared what the plan was going to be when we renewed their lease, and wanted to ensure that they knew how much I appreciated their long term tenancy in the property. 

I grew up in the finger lakes and am intrigued by the price point, but concerned/unsure about the local economy.

This platform has an abundance of tools for learning and making connections with people who share your interests.

I wouldn't jump into a deal just because the seller is offering to carry the note, if that's the concern.

With the numbers you shared, and the common 75% of ARV calculation you would be heavily underwater if you buy this house at 300,000.
