The value of the property determined by the appraiser

A person who has the knowledge and expertise necessary to estimate the value of a property. An appraiser acts independently of the buying and selling parties in a transaction in order to arrive at their fair value of an asset without bias.

Aka arm’s length sale. A transaction in which both buyer and seller act willingly, independently and in their own self-interest.

Automated Valuation Model. AVMs are online databases that try to match up similar properties to give an idea of the range of sales prices that have historically been recorded. County assessors were some of the first to use such services because of budgetary and personnel limitations. However, this information is limited to factual data, such as the size of the house, number of rooms and bedrooms, age of the house, and distance surrounding the house. Fast and cheap, but reliant on the (in)accuracies of public data.


A Broker Price Opinion (BPO) is an estimate of a property’s anticipated sale price as determined by a real estate broker or agent. It is often requested by financial institutions, mortgage companies or other entities that need to assess the market value of a property. BPOs are commonly used in situations where a full appraisal may not be necessary or practical. Real estate brokers/agents with knowledge of the local market perform BPOs by visiting a property, taking pictures, then evaluating the property considering factors such as its condition, location, comparable sales in the area and current market trends. BPOs are typically less expensive and quicker to obtain than a full appraisal, making them a cost-effective option in certain situations. It is important to note that BPOs may not be as comprehensive as a formal appraisal and are not accepted in all situations, depending on regulations and the specific requirements of the requesting party.

Close of Escrow. Close of escrow means essentially that a real estate transaction has been completed and that the sale is final. An ‘escrow’ is a common feature of transactions. It is an independent third party that holds all monetary funds and documents until the close of sale. The seller of the property transfers all documents to the escrow agent, who holds them until the buyer transfers the money for sale to the agent who ultimately transfers it to the seller. Once this is done, it completes the transaction and is know as the closing of escrow, or often just “the closing.”

Additional information required to justify methods used in valuation

Often shortened to "comp". Properties that are substantially equivalent to the subject property. Comps express estimate of value for the subject property. Normally, such properties have been recently sold or leased and are similar to the property being evaluated.

A desktop appraisal, also known as a desktop valuation or desktop assessment, is a method of property valuation that is conducted without physically inspecting the property. Instead of visiting the property in person, the appraiser relies on various data sources and information to determine an estimated value.

They analyze these details and apply their expertise to assess the property's value based on the available information.

This refers to a smaller, loosely defined geographical location within a larger city, town, or suburb. They often consist of social communities with considerable face-to-face interaction among their members. Neighborhoods are important because prices vary considerably in different neighborhoods.

The neighborhood boundaries define the subject market area, generally in terms of the four major landmarks to the north, south, east, and west.

A class of property owned by a lender-typically a bank, government agency, or government loan insurer-after an unsuccessful sale at a foreclosure auction.[1] A foreclosing beneficiary will typically set the opening bid at a foreclosure auction for at least the outstanding loan amount. If there are no bidders that are interested, then the beneficiary will legally repossess the property. This is commonly the case when the amount owed on the home is higher than the current market value of this foreclosure property, such as with a high loan-to-value mortgage following a real estate bubble. As soon as the beneficiary repossesses the property it is listed on their books as REO and categorized as an asset (non-performing asset).

Aka Liquidation: A type of RMV that is specifically for liquidation or short sale purposes. The most recent product in an SPO RMV will always be an interior valuation product. Most SPOs include a purchase offer which needs to be reviewed and commented on in the RMV.

A short sale is defined as a transaction where title transfers, where the sales price is insufficient to pay the total of all liens and costs of sale, and where the seller does not bring sufficient liquid assets to the closing to cure all deficiencies. Short sale values are typically sold at a lesser value than average market value (if short sales are not typical market value), meaning the partner is taking a loss in sale value from. This typically means the seller's principal is greater than sales price or (current market value), providing the partner with a negative balance on property sale.
