Comps 101: A Complete Guide to Comparable Properties and CMA Reports

https://www.newwestern.com/wp-content/uploads/2023/01/Property-Comps-scaled-1.jpg

The phrase “pulling comps” gets a lot of buzz in the real estate world –– and for good reason! Comps, or comparable properties, help create a baseline valuation for a home, which in turn influences things like the list price, purchase offer, appraisal, and more. Because comps hold so much weight in the industry, real estate professionals often run a Comparative Market Analysis (CMA) when evaluating a property. 

But because they’re not standardized, not all CMA reports are created equal. Before entering into any type of real estate transaction, it’s important to understand what qualifies as a good comp and a good CMA report. Let’s start from the beginning.

What Are Comps?

The term “comps” usually refers to recently sold properties that have similarities to one another in location, size, and features. However, in markets where sales are slim or where values are rapidly changing, comps may be expanded to include for-sale and pending properties as well. 

Comps are most valuable when they hold the closest similarities to the property being evaluated. The idea is to try to compare “apples to apples”, so to speak. As such, a good comp can usually be qualified by the following indicators:

  • Location: The closer the better! Ideally, a comp will be located within the same neighborhood, but usually a good rule of thumb dictates that comps be located within a max one-mile radius from the property (or up to a five-mile radius in remote, rural areas). The close proximity of comps helps to account for local features and market conditions.    
  • Size: Both the square footage of the home and the size of the lot should be taken into account when determining a good comp. A closely-matched home and lot size helps to more accurately look at value.  
  • Features: Similar home features also help determine compatibility. Compare the number of bedrooms, number of bathrooms, and number of overall rooms first. Then consider additional desirable features such as garage space, outdoor space, pool, water frontage, and more.
  • Condition: Recent renovations add value to a property, so a good comp will have a similar condition level. This element is more subjective than the others, of course, but looking up the age of the roof, the systems, and any major updates can help bring some objectivity to the process.
  • Sale date: Usually, accurate comps include sales made within the last six months, with closer sale dates being the best. However, in slow market conditions, this figure may need to be adjusted to more like twelve months, and in hot market conditions, it may be more accurate to compare sales only within the last month.  

All of these elements must be balanced against one another to determine the best comps. For example, which is a closer indicator of value: a comp across the street without renovations that sold six months ago or a comp three neighborhoods over with similar updates that sold last month? That’s where the Comparative Market Analysis comes into play. 

What Is a CMA? 

A Comparative Market Analysis (CMA) is a report that looks at three to five comps side-by-side to help predict a home’s worth. Because no two homes are ever completely equal, it’s important to analyze several comps in tandem.

CMA data is pulled from the Multiple Listing Service (MLS). Anyone with access to the MLS can create a CMA. But that doesn’t mean that every CMA is accurate. Some CMAs aggregated by algorithms fail to take relevant conditions into account.

A good CMA should provide the following information (usually delivered in a table format):

  • Property status (sold, under contract, or for sale)
  • List price
  • List price per square foot
  • Sold price
  • Sold price per square foot
  • Date built
  • Date sold
  • Days on market
  • Square footage
  • Acreage
  • Home type (construction and/or style)
  • Number of bedrooms
  • Number of bathrooms
  • Water/sewer type (city or well/septic)
  • Important features based on locale (such as view, frontage, fireplace, parking, flooring, foundation, access, HOA, etc.)   

Remember, when it comes to CMAs, there isn’t an official “comps standard” or set of rules that everyone is required to follow, so results could vary. Therefore, it’s important to meticulously choose the best-available properties before making any significant transaction decisions. 

Why Comps and CMA Reports Are Important

While houses traditionally have certain value-identifying commonalities, the range in a home’s value can vary widely based on subjective factors that reflect nothing more than buyer preferences. Factors like demand and market fluctuations add to that constant variation as well.

Comps and CMA reports are important because they help to pinpoint a value within that constantly flexing range by determining a Fair Market Value (FMV). Fair Market Value is the worth of a home as it stands under the current market conditions. Unlike sales histories and prior appraisals, Fair Market Value predicts what a buyer would likely pay in the “fair market” today. The only way to estimate FMV is by looking at current comparable sales.

Comps and CMA reports can also help project the After Repair Value (ARV) for investors. An investor who intends to flip a home may want to purchase a distressed property for under market value, if possible. Before committing, they’ll also want to project how much the property will be worth after all updates are completed. Running a CMA that compares homes with similar renovations will help determine ARV. That number tells the investor whether or not the potential profits are enough to warrant the purchase and repair costs.  

Who Uses Comps and CMA Reports?

Comps and CMA reports are used by people and professionals at almost every stage of a property transaction.

  • Sellers. Sellers need to look at comps to determine FMV and set a competitive list price.
  • Buyers. Conversely, buyers will want to look at comps to make sure that the list price is fair, then make their offer accordingly. 
  • Real estate agents. Both the buyers’ agent and sellers’ agent should use CMAs to assist in this process. Agents also look at CMAs in general as a way to stay in touch with local market trends. 
  • Investors. An investor’s profitability depends on accurate comps in order to determine both FMV and ARV. 
  • Appraisers. Appraisers look at comps, run their own CMA, and make value adjustments to determine a home’s appraised value. 
  • Lenders. In turn, lenders look at the appraised value of the home before approving a loan. If the appraised value falls below the purchase price, the loan may be denied.
  • Tax assessors. In order to set property taxes, the county tax assessor will also look at comps and run their own CMA to create an assessed value.  

Understanding what makes a good comp and good CMA is important at every stage. According to Fannie Mae, 12% to 14% of appraisals come back undervalued; to appeal those appraisals, sellers need to be able to analyze good comps. Likewise, the National Taxpayers Union Foundation estimates that anywhere between 30% and 60% of homes are over-assessed for taxes; buyers looking to appeal those assessments will need good comps as well.    

How Can I Obtain Good Comps For My Property?

As with most things these days, technology has made great strides regarding access, accuracy, and ease-of-use. In the past, you had to hire a professional to pull comps before the sale of your home. Today, pulling a property comp to estimate your house’s value is as simple as entering your address into an online form.

But as previously mentioned, it is important to consider the source before trusting a CMA. Local real estate agents routinely scoff at the CMAs obtained from sources like Zillow, Redfin, and Realtor.com; the data often comes back skewed by whatever marker of a “good comp” the algorithm favored, which isn’t necessarily a reflection of true FMV for the area.

Some buyers and sellers choose to pull their own comps by looking at public records of recent sales. While this could be a good way to look at numbers, that method will still need to be cross-referenced against listing info to take more subjective elements (like condition) into account.  

The New Western Comp System offers a hybrid alternative for buyers and sellers who want the ease of online data combined with real-world wisdom that can only come from hands-on interfacers.

At the end of the day, if you’re having trouble determining whether or not a CMA reflects the true value of your home, consider seeking the advice of someone who has experience pulling comps, such as a professional appraiser. If you don’t personally know anyone who could help you, there are plenty of online resources and tips to ensure you are properly pulling your report.
