An online estimator can only guess at your home's value. A Comparative Market Analysis from Mark Spain Real Estate gives you a real number built from recent sales, current competition, and an actual look at your home, and we provide it free as part of every listing conversation.
If you've ever checked your home's value on one of those instant estimate websites, you've probably noticed the numbers swing wildly from site to site. One says $410,000, another says $465,000, and neither one has ever set foot inside your kitchen. That's because online estimators run on public records and algorithms, and they can't see your updated kitchen, your finished basement, or the new construction down the street that just changed what buyers will pay.
A Comparative Market Analysis, or CMA, is the human version of that estimate. A local agent studies homes like yours that recently sold, homes currently for sale that you'll compete with, and the specifics of your property, then walks you through a realistic price range. At Mark Spain Real Estate, we build a free CMA for every client, and it's the foundation of a selling plan you can actually trust.
Here's the honest difference. An estimator knows your square footage, your lot size, and your tax record. It doesn't know that you replaced the roof last year, that your floor plan is the one buyers in your school district hunt for, or that three homes on your street just sold above asking. Those details routinely move a price by tens of thousands of dollars, and only a CMA captures them.
A CMA also comes with a person. When we sit down with you (in person or on a call), we explain which sales we compared, why we picked them, and what we'd list your home at today. You can ask questions, push back, and see the math. That turns "a website says my house is worth X" into "here's what homes like mine are actually selling for, and here's the plan."
And because we conduct a CMA as a standard part of our listing process, there's no cost and no pressure. Some sellers use it to make a go/no-go decision. Some use it to time their sale. Some pair it with our Guaranteed Cash Offer program when speed and certainty matter most. Either way, you start from real numbers instead of a guess.
When you request a CMA from Mark Spain Real Estate, here's what goes into it:

A few honest things to think about before you request a CMA:
How accurate is a CMA compared to an online estimator?
A CMA is far more precise because it's built by an agent who knows your market and has seen your home's specifics. Estimators can be off by large margins, especially for homes with upgrades, unusual features, or fast-changing neighborhoods. A CMA gives you a defensible range based on real, recent sales.
How much does a Comparative Market Analysis cost?
Nothing. We provide a free CMA as a standard part of our listing process. There's no fee and no obligation.
How long does it take to get a CMA?
Usually just a few days from your first conversation. We'll schedule a time to learn about your home (and often see it), then walk you through the analysis and answer your questions.
Can I get a CMA if I'm not ready to sell yet?
Absolutely. Many clients request a CMA a year or more before they plan to sell. It's a great way to understand your equity, plan your budget, and decide on timing.
Online estimators are fine for a casual glance, but when you're making a real decision about your home, you deserve a real analysis. A free CMA from Mark Spain Real Estate gives you recent sales, current competition, and a local expert who explains every number, with no cost and no obligation.
Whether your home is in Atlanta, Dallas, Tampa, Orlando, or every other market we serve, we're ready to help you move from a rough guess to a clear selling plan, with a full market listing or, for eligible homes, a Guaranteed Cash Offer.
