What is Fair Market Value?
Fair market value (FMV) is the price a property would sell for on the open market under normal conditions -- meaning a willing buyer and willing seller, both reasonably informed, neither under pressure to act, and with reasonable time to complete the transaction. It represents what a typical, arms-length transaction would produce, not a distressed sale, foreclosure, or forced liquidation.
For real estate investors, understanding the distinction between fair market value and other valuation concepts is essential. FMV represents the property's value in its current condition to a typical buyer. The after-repair value (ARV) represents what the property would be worth after renovation. The gap between FMV (current condition) and ARV (renovated condition) is where investor profit potential lives.
How fair market value is determined
FMV is established through comparable sales analysis -- looking at what similar properties in the same area have recently sold for. The most reliable method uses three to six comparable sales that are similar in size, age, condition, and location to the subject property. Adjustments are made for differences: a comp with an extra bedroom might be adjusted downward, while one with a smaller lot might be adjusted upward.
Three primary approaches to determining FMV:
- Sales comparison approach: The most common method for residential properties. Compare recent sales of similar properties and adjust for differences. This is what appraisers primarily use.
- Income approach: Used for rental/income properties. Value is derived from the property's income-producing ability using cap rates and NOI.
- Cost approach: Estimates the cost to build an equivalent property from scratch minus depreciation plus land value. Less common for existing homes but used for unique properties or new construction.
FMV vs other values
| Value Type | What It Represents |
|---|---|
| Fair market value | Current condition, normal sale conditions |
| After-repair value (ARV) | Value after renovation |
| Tax assessed value | County's assessment for property tax purposes (often below FMV) |
| AVM (automated valuation) | Algorithm-generated estimate (varying accuracy) |
| Insurance value | Replacement cost for insurance purposes |
| Liquidation value | Quick-sale price under pressure |
Why investors buy below FMV
The entire wholesale and investment model is built on purchasing properties below fair market value. This isn't exploitation -- it's a trade. Motivated sellers accept below-FMV offers because they're receiving something valuable in return: speed, certainty, convenience, no repairs required, no agent commissions, and a solution to whatever problem is driving the sale. The discount below FMV is the premium the seller pays for these benefits.
How far below FMV investors buy depends on the exit strategy. Wholesalers typically contract at 60-70% of ARV minus repairs (which is well below current FMV). Flippers buy at 70-75% of ARV minus repairs. Rental investors may pay closer to FMV if the cash flow numbers work because they're holding long-term and current value matters less than income.
