Real Estate Appreciation Trends in Southern Maryland: St. Mary’s, Calvert & Charles Counties

If you’re a homeowner in Southern Maryland, you’ve probably wondered something like: “Okay, my assessment went up… but what does that actually mean for my home value?” Or maybe: “Are prices in St. Mary’s, Calvert, and Charles Counties still going up, or has everything cooled off?”  

I get these questions constantly—from long‑time owners, newer buyers, and “I’m just watching” folks. You don’t need more hype; you need a clear picture of how values are trending and what that means for your equity.  

I’m Amanda Holmes, a full‑time Southern Maryland Realtor, and I spend a lot of time translating charts and reassessment letters into plain English. Let’s walk through what’s happening with appreciation in St. Mary’s, Calvert, and Charles Counties right now.

 The big picture: values are still rising, just more calmly

Across Southern Maryland, property values are still going up, but the pace has shifted from “sprint” to “jog.”  

Recent reassessments for 2026 show:  

- Calvert County: total property values up about 9%, with residential values up around 8.8%.

- Charles County: total property values up about 12.5%, with residential values up roughly 12.7%.

- St. Mary’s County: total property values up about 10.7%, with residential values up around 10.5%.

That’s on top of several strong years before this. So while the rate of growth has moderated compared to some earlier cycles, most homeowners in Southern Maryland have seen meaningful appreciation over the last few years.

From where I sit, that means many of you are sitting on more equity than you realize—even if it doesn’t feel like it when you’re just thinking about property taxes.

 St. Mary’s County: steady appreciation with solid demand

In St. Mary’s County, appreciation has been strong but is settling into a more sustainable pattern.  

On the data side:  

- The 2026 reassessment showed residential values up about 10.5% over the last cycle.

- Recent sales put the median home price around $440,000, up roughly 7.6% year‑over‑year.

On the ground, that looks like this: homes near Pax River, California, and Leonardtown that were comfortably in the 300s not long ago are now regularly trading in the 400s, especially if they’re reasonably updated.  

If you own in St. Mary’s, chances are your home has gained a healthy chunk of value since 2020. The appreciation pace has cooled from the sharp spikes, but it’s still moving in the right direction—which is exactly what you want for long‑term stability.

 Calvert County: slower but solid growth

In Calvert County, appreciation is more modest—but still very real.  

Recent numbers show: 

- A 2026 reassessment increase of about 9% overall, with residential values up 8.8%.

- A median sale price around $460,000 as of late 2025, up about 1.1% year‑over‑year.

- Longer‑term price indices also show clear growth from 2020 through 2024.

What this feels like in real life: values are still moving up, just not in huge leaps. Buyers are price‑sensitive, but they’re willing to pay for space, trees, and water‑adjacent living—especially if the commute up Route 4 works for them.  

If you’ve owned your Calvert home for several years, you’ve likely seen a strong run‑up already, and now you’re in a steadier, more predictable appreciation phase.

 Charles County: strong recent gains with some cooling at the edges

Charles County has seen some of the stronger assessment increases recently, even as parts of the market feel more negotiable for buyers.  

From the reassessment   

- Overall property values are up about 12.5%, with residential properties up roughly 12.7%.

Day‑to‑day, that looks like:  

- Many homes showing solid appreciation compared to a few years ago.  

- Certain segments—especially some townhomes and commuter‑focused neighborhoods—feeling a bit more buyer‑friendly as inventory grows.  

So you get this interesting mix: long‑term appreciation is strong, but the current pace of new price jumps is more measured. As an owner, that means your equity picture has likely improved significantly over the past few years, even if the market feels less “hot” right this second.

 What these appreciation trends mean for you

Appreciation trends are nice, but here’s how they actually matter in your day‑to‑day decision‑making:

- If you’re thinking about selling:  

  In all three counties, there’s a good chance your home is worth more than you think—especially if you’ve owned it for 3–5+ years. The days of automatic over‑asking offers are mostly behind us, but strong pricing and good preparation can still turn that appreciation into real dollars at closing.

- If you’re thinking about buying:  

  These trends tell you that Southern Maryland still has a generally upward trajectory. You’re not buying into a declining market; you’re buying into one that’s maturing. That said, you need to be realistic about price levels and plan for long‑term ownership, not quick flips.

- If you’re staying put for now:  

  Appreciation boosts your equity and options—for future moves, HELOCs, or just peace of mind. It also means keeping up with maintenance matters, because buyers and appraisers will compare your home to those higher‑value neighbors when the time comes.

 People also ask

1. Have home values in Southern Maryland peaked?  

We’re past the most dramatic growth years, but current data still shows property values rising—just at a more moderate pace.  That’s usually healthier for long‑term stability. It’s less “rocket ship” and more “steady climb,” which is good if you’re focused on long‑term equity.

2. Which county is appreciating the fastest—St. Mary’s, Calvert, or Charles?  

Based on recent reassessments, Charles County has seen slightly higher percentage increases (around 12.5% overall), followed by St. Mary’s (about 10.7%) and Calvert (around 9%).  But within those counties, specific neighborhoods and price points can behave very differently.

3. Are higher assessments the same as higher market value?  

Not exactly, but they’re related. Assessments aim to mirror market value trends, and they often lag real‑time sales. They’re a useful clue that your area has appreciated, but they’re not a precise valuation for what a buyer would pay for your specific home today.

4. How can I tell how much my home has appreciated?  

The best way is to compare what similar homes in your immediate area are selling for now versus a few years ago, and then adjust for your home’s size, condition, and updates. I typically combine reassessment info, recent sales, and a walkthrough of your home to estimate your current market value and equity.

5. Is now a good time to use my equity to move or refinance?  

That depends on your plans, interest rate, and monthly budget. Appreciations trends mean many Southern Maryland owners have more equity to work with, but rates and purchase prices also matter. This is where it helps to run numbers with both a Realtor and a lender so you’re not making a decision based on assessments alone.
