Ohio uses which document as the security instrument for real estate loans?

Deed of trust is incorrect as it's used in trust deed states where a third party (trustee) holds title until the loan is repaid. Ohio does not use this security instrument for real estate loans.

Security deed is primarily used in Georgia and a few other states, not Ohio. It functions similarly to a mortgage but has different legal terminology and requirements.

Land contract is a financing agreement where seller retains title until buyer completes payments, not a security instrument used by traditional lenders in Ohio.
