An Overview of Two Common Property Appraisal Methods
Admin • October 18, 2021

Accurate home appraisals benefit both property buyers and sellers. Appraisals help buyers to get mortgage approval and avoid overpaying for their houses. On the other hand, sellers avoid underselling their homes. Below are two common approaches to property appraisals.
1. The Sales Comparison Approach
The sales comparison approach determines the house's value based on the prices of similar houses that others have recently sold in the area. The comparable properties should be as similar as possible to the one appraised. Below are some of the things that should be similar.
Physical Properties
Many buyers judge homes by their physical properties. Physical properties include things like the property's:
- Size (square feet and number of rooms)
- Unique features or amenities, such as swimming pools
- Architectural style
Neighborhood
All the compared properties should be in the same neighborhood. Location factors, such as transport networks, crime rates, and employment opportunities affect housing prices.
Age
Many properties (but not all) depreciate in price over time. Thus, the appraisal should compare a six-year-old house to properties within the same age range.
Condition
A home's condition changes with time and the changes tend to be negative. Materials degrade, and some people take better care of their homes than others. The appraiser will only pick properties in the area with the same conditions.
Terms of Sale
A property's terms of sale affect its price, so the comparison should be between properties with similar terms of sale. For example, the appraiser should only compare a property under foreclosure to properties sold under foreclosure.
2. The Cost Approach
The cost approach determines how much you would need to build a similar structure in the same neighborhood. You need land to build a house. Thus, the cost of a house depends on both the construction and land cost. Below are the salient factors or both costs.
Land Cost
The appraisal will consider the market value of the land. Land value depends on:
- The location. For example, lots in major urban centers tend to have higher values than those in rural locations.
- The topography. This determines the use of and ease of construction on the land.
- The land size. Larger lots typically cost more than smaller ones.
- Nearby amenities. For example, utilities, educational centers, and hospitals affect the land value - more amenities usually mean higher values.
These are only a few factors - many other factors, including the land use, also matter.
Construction Cost
Construction cost considers how much you would need to build the exact house. Major factors here include:
- The nature of the site - for example, the type of preparations you need before starting construction
- The local labor costs
- The type, quality, and cost of construction materials
- The architectural design of the property
- The size of the property since bigger properties cost more to construct
- The cost of improvements, such as landscaping, on the property
Depreciation
Lastly, the appraiser will also consider the negative effects that time has had on the property. The consideration is critical since properties of different ages may require different budgets to reconstruct. The major factors here include:
- Deterioration such as the wear and tear of materials
- Outdated appliances or installations
- Neighborhood changes, such as major employers that have since shut down their operations

When someone inherits property—whether it’s real estate, stocks, or other assets—one of the most important (and often overlooked) tax concepts is the “step-up in basis.” An IRS step-up appraisal is the process used to determine the fair market value of an asset at the time of the original owner’s death. That value becomes the new tax basis for the heir. Understanding how this works can save—or cost—significant money when the asset is eventually sold. What Does “Step-Up in Basis” Mean? “Basis” is essentially what an asset is worth for tax purposes. Normally, if you buy something, your basis is what you paid for it. But when you inherit property, the IRS allows that basis to be “stepped up” to the asset’s fair market value as of the date of death. Example: A parent buys a home for $100,000 decades ago At the time of their passing, the home is worth $700,000 The heir’s new basis becomes $700,000—not $100,000 If the heir sells the home for $710,000, they only pay capital gains tax on $10,000—not $610,000. That’s the power of the step-up. What Is an IRS Step-Up Appraisal? An IRS step-up appraisal is a formal valuation that establishes the fair market value of an inherited asset as of a specific date—usually the date of death. For real estate, this means a licensed appraiser evaluates: Comparable sales (comps) Property condition Market trends at that time Location and unique characteristics The result is a retrospective appraisal , meaning it determines value as of a past date, not the current market. Why Is It Important? A step-up appraisal is critical for several reasons: 1. Reduces Capital Gains Taxes Without a proper appraisal, the IRS may assume a lower basis, increasing taxable gains when the asset is sold. 2. Provides Documentation If the IRS ever questions the reported value, a professional appraisal serves as defensible evidence. 3. Helps with Estate Planning and Reporting Executors and heirs need accurate values for estate filings and distribution decisions. When Do You Need One? You typically need a step-up appraisal when: You inherit real estate and plan to sell it The estate did not already establish a value for tax purposes Significant time has passed since the date of death There’s potential for IRS scrutiny (high-value assets) Even if you don’t plan to sell immediately, getting the appraisal early can prevent headaches later. Date of Death vs. Alternate Valuation Date Most step-up appraisals use the date of death as the valuation date. However, in some cases, the estate may elect an alternate valuation date (six months later), if it reduces estate taxes. This decision is usually made by the estate’s executor in consultation with tax professionals. What Makes a Good Step-Up Appraisal? Not all appraisals are equal—especially when dealing with the IRS. A reliable step-up appraisal should: Be completed by a state-licensed or certified appraiser Follow Uniform Standards of Professional Appraisal Practice (USPAP) Clearly state it is a retrospective appraisal Include strong comparable sales data from the relevant time period Be well-documented and defensible Common Mistakes to Avoid Using current market value instead of date-of-death value Relying on informal estimates (like Zillow) Waiting too long to gather historical data Failing to get an appraisal at all These missteps can lead to disputes or higher taxes. Final Thoughts An IRS step-up appraisal might not be the first thing on your mind after inheriting property, but it plays a major role in determining future tax liability. Getting it right can mean the difference between a manageable tax bill and a costly surprise. If you’ve inherited property—or expect to—it’s worth consulting with a qualified appraiser and tax advisor early in the process. A little diligence upfront can protect you financially down the road.
