What type of transaction involves a property seller providing all or part of the financing?

The correct choice is seller financing, as it specifically refers to a transaction where the seller of a property takes on the role of the lender, providing financing to the buyer either in full or in part. In this arrangement, the buyer makes payments directly to the seller instead of obtaining a traditional mortgage from a bank or financial institution. This type of financing can be advantageous in situations where traditional lending may not be accessible to the buyer due to credit issues or other factors.

Seller financing can also be beneficial for sellers, as it may facilitate a quicker sale and attract more potential buyers, particularly if they offer more favorable terms than conventional lenders. It often involves a promissory note that outlines the repayment terms, interest rates, and consequences of default, just as a traditional mortgage would.

The other options pertain to different types of financing and do not involve the seller providing financing directly. Conventional financing refers to mortgages issued by private lenders that are not insured or guaranteed by the government, while conforming loans are conventional loans that meet specific criteria set by government-sponsored entities like Fannie Mae and Freddie Mac. An assumable mortgage is one that allows a buyer to take over the seller's existing mortgage, which does not inherently involve the seller providing financing directly to the buyer.
