No, you pretty much have to be a "financial institution" of some sort in order to be required to issue a 1099-INT. Read the Box 1 instructions and decide.
Box 1 instructions:
"Enter taxable interest not included in box 3. Include amounts of $10 or more, whether or not designated as interest, that are paid or credited to the person's account by savings and loan associations, mutual savings banks not having capital stock represented by shares, building and loan associations, cooperative banks, homestead associations, credit unions, or similar organizations. Include interest on bank deposits, accumulated dividends paid by a life insurance company, indebtedness (including bonds, debentures, notes, and certificates other than those of the U.S. Treasury) issued in registered form or of a type offered to the public, or amounts from which you withheld federal income tax or foreign tax. In addition, report interest of $10 or more attributable to a TIH of a WHFIT, or accrued by a real estate mortgage investment conduit (REMIC), a financial asset securitization investment trust (FASIT) regular interest holder, or paid to a collateralized debt obligation (CDO) holder, as explained later.
Also include interest of $600 or more paid in the course of your trade or business not meeting the above criteria, such as interest on delayed death benefits paid by a life insurance company, interest received with damages, interest on a state or federal income tax refund, or interest attributable to certain notional principal contracts with nonperiodic payments. See Regulations section 1.446-3T(g)(4)."

Yes, the interst paid and/or received on a seller-financed loan on an Installement Sale must be included on your income tax return. If you're the seller, report the interest on Schedule B, and the buyer reports the interest as mortgage interest on Schedule A, if enough to claim itemized deductions.
Here's how to enter seller-financed loan interest:.
