Buyer can make up the difference in cash.The lender cares about the appraisal only to the extent it affects the loan-to-value ratio. A low appraisal does not mean the lender won't lend. It means the lender will make a loan based on the ratio agreed to in the contract at the appraised value. Sometimes the buyer's lender will not allow the buyer to give cash for the difference and, in that event, have the buyer pay instead some of the seller's closing costs.
Automated valuation models (AVMs) are growing in acceptance. These rely on statistical models such as multiple regression analysis, machine learning algorithms or geographic information systems (GIS). While AVMs can be quite accurate, particularly when used in a very homogeneous area, there is also evidence that AVMs are not accurate in other instances such as when they are used in rural areas, or when the appraised property does not conform well to the neighborhood.
These appraisers also perform valuations on commercial property ranging from single to multiple tenant office buildings, shopping centers, retail, industrial, malls, hospitals, health care facilities, warehouses, and hotels to multi-family apartment buildings, co-ops, senior housing, condominium developments, and even vacant land, agricultural, and golf courses. Regardless of the property type or local zoning, they'll determine the highest and best use of the project and assess the value using the actual or projected cash flow from the property's rent roll and financial statements, using both cap rates for capitalizing year one net operating income (NOI) and discounted cash flow (DCF) of multiple future income streams. If you're a commercial lender, investor, builder, contractor, architect, or agent, you'll want to use these appraisers to conduct a feasibility analysis of any income producing real estate project you may be considering. They can also help consult on construction costs and projected absorption rates. They generally produce a commercial narrative appraisal when engaged for any commercial assignment.
