Final answer:
A Seller carryback loan is typically the least expensive mortgage loan to create, avoiding many fees and closing costs of traditional loans.
Step-by-step explanation:
The question relates to the cost of creating different types of mortgage loans. The answer is that a Seller carryback loan is usually the least expensive to create. Seller carryback financing is when the seller of a property provides a loan to the buyer to cover part or all of the purchase price. This type of loan avoids many of the fees and closing costs associated with traditional mortgages such as FHA loans, VA loans, and conventional mortgages. Additionally, seller carryback loans may have fewer requirements and can be faster to arrange, further reducing costs.
