Mortgage on both the purchased real estate and personal property of a durable type. The entire amount financed is considered one mortgage. In residential real estate, a builder might include a stove, refrigerator, dishwasher, or air conditioning in the sale price. For commercial real estate, certain equipment or furniture is often included in the sales price. The advantage to the purchaser is that these items can be financed over a much longer period and at a much lower interest rate than if a separate financial instrument was used. For the builder or seller, these items serve as inducements used in financing the sale.
