Most real property (real estate) transactions for the sale and purchase of property involve a buyer who secures financing (a mortgage loan) from a bank for the purchase of the property and transfers the lump sum purchase price to the seller at the closing, in exchange for the seller transferring the deed (title) to the buyer—or to an escrow for safekeeping until the buyer repays the loan to the lender.

But if the buyer does not have good credit or a sufficient credit history—and especially if the seller wants to sell the property to a specific person—the seller may consider seller financing for the transaction. In a seller-financed transaction the buyer signs a promissory note promising to pay the purchase price of the property to the seller over time, plus a stated interest rate, which is included in a monthly installment payment projected over some number of months or years.

Seller financing is often structured for the buyer to make monthly payments for a number of years (five years, for example) and then make a balloon payment for the remaining balance of the loan. This seller financing structure anticipates the buyer being able to secure a traditional loan from a bank with improved creditworthiness and some equity in the property (a home, for example).

There are pros and cons to seller financing for both the buyer and the seller. Seller financing may reduce closing costs and shorten the time to closing, but the buyer may pay a higher interest rate and the seller will take on risk that the buyer will default on the payments and the seller will have to go through the legal process of evicting the buyer from the property.

In Michigan, seller financing is a legal alternative to traditional mortgage lending for real estate transactions. This arrangement involves the seller acting as the lender, providing the buyer with a loan to purchase the property. The buyer signs a promissory note agreeing to pay the seller the purchase price plus interest over a specified period. Payments are typically made in monthly installments, with a balloon payment often due at the end of the term, which might be structured around a 5-year period. Seller financing can offer benefits such as lower closing costs and a quicker closing process. However, it also carries risks, including the potential for a higher interest rate for the buyer and the risk of default for the seller, which could lead to the legal process of eviction. Michigan law requires that seller-financed transactions comply with state statutes governing real estate sales, promissory notes, and mortgages. It's important for both parties to have a clear, written agreement outlining the terms of the financing, and they may wish to consult with an attorney to ensure the transaction adheres to all applicable laws and to protect their interests.
