ran a seller-financed deal on a duplex in youngstown back in 2021, same situation, same paranoia. what gets recorded is the mortgage instrument itself, not just a placeholder lien. in ohio that means the full document goes into the county recorder's database, stamped and indexed, and yes the rate, the balance, the balloon date, all of it is visible to anyone with a recorder.gov login or who walks into the stark county recorder's office. the promissory note itself is a separate document and does NOT get recorded, that's the piece with the payment schedule and the fine print, but the mortgage or deed of trust that secures it will reference enough of the key terms that a note broker can reconstruct your deal in about four minutes. i had three calls within ten days of my youngstown closing from people i'd never heard of who knew my exact maturity date.
what i'd push your attorney on is whether the recorded mortgage can be drafted to reference the note by its date and parties only, rather than restating the rate and balloon explicitly in the mortgage body. some ohio attorneys do this, some don't bother unless you ask. the note itself stays private as long as you don't hand it over, but the mortgage language is where your exposure is. is your attorney using a standard form mortgage or drafting it specifically for this transaction, because that one difference is going to determine how much of your negotiating position is sitting in a public database by february.
