Three different numbers show up when people talk about home value, and they almost never match each other:
- Assessed value (what the county says your home is worth, for tax purposes)
- Appraised value (what a licensed appraiser says your home is worth, for a specific purpose like a refinance)
- Market value (what a buyer will actually pay)
And then there's the fourth, increasingly inescapable number: Zillow's Zestimate, or its cousins from Redfin, Realtor.com, and a dozen newer apps. Most homeowners check it monthly. Most buyers and sellers act like it means something definitive.
It doesn't. Here's why, and what does.
What an automated valuation actually is
The Zestimate, the Redfin Estimate, and every similar tool is what's called an automated valuation model (AVM). It's an algorithm. It looks at recent sales in the area, public records on your home (square footage, lot size, year built), and applies statistical adjustments based on how it thinks your home compares to comps.
That sounds reasonable. The problem is that the algorithm has no idea:
- Whether your kitchen was renovated last year or last century
- Whether your roof is six years old or nineteen
- Whether your home backs up to a busy road or a quiet park
- Whether you have impact windows (hurricane discount) or not
- Whether your floor plan has been updated
- Whether the home next door — that "comp" feeding the algorithm — sold to a flipper at a discount, or to a related party for a song
Between 2018 and 2021, Zillow itself bet billions on its own AVM by buying homes directly from sellers based on Zestimate values, then trying to flip them. They lost over $400 million and shut the program down in 2021. If their algorithm couldn't reliably price homes well enough for them to profit, it can't reliably price your home either.
What an actual valuation looks at
A proper comparative market analysis (CMA) is what real estate agents prepare for sellers, and it's what shapes informed offers from buyers. It's done by a human who knows the market, with software that pulls real MLS data, then adjusted with judgment.
Recent comparable sales
The bedrock of any valuation. We pull homes that have actually sold (not listed, not pending — closed) within the last 90 days, in your immediate area, similar in size, age, and configuration. The closer the comps in time and geography, the more weight they carry.
Active competing listings
What's currently on the market in your range. These tell us what buyers are choosing between right now. If everything similar to your home is priced at $425k and yours is being prepared at $475k, we'll see resistance.
Pending sales
Listings under contract but not yet closed. These reflect the most current buyer sentiment.
Days on market trends
How long similar homes are sitting before they sell. In a strong market, similar homes go under contract in 14 days; in a soft one, they take 90+.
Adjustments for your specific home
Once we have the comps, we adjust each one for the differences from your home:
- Square footage: typically $80–$200/sqft difference, depending on the segment
- Bedrooms / bathrooms: $5k–$15k per additional bath, less for bedrooms
- Lot size: especially relevant in DeLand for older homes on larger lots
- Garage spaces: ~$3k–$8k each
- Pool: $20k–$40k in DeLand market, depending on style and condition
- Updated kitchen / baths: $10k–$40k depending on scope
- Roof age: roof under 5 years adds, roof over 15 years subtracts
- HVAC age: similar logic
- Hurricane shutters / impact windows: insurance discount premium
- Location specifics: backing to a park (+), backing to a busy road (–), corner lot (varies)
The Zestimate is a starting point for curiosity. It is not a number you should price a sale on, write an offer with, or plan a refinance around.
What actually drives home value in DeLand specifically
Real estate is hyper-local. Here's what matters most in the DeLand and West Volusia market right now:
Roof age
Florida insurers care intensely about roof age. A new roof can add value not directly equal to the cost, but indirectly through dramatically lower insurance premiums for the next owner.
Hurricane preparation
Impact windows, accordion or roll-down shutters, hurricane-rated garage doors. Insurance discounts for these can be 30%+, which translates to thousands per year in savings.
Flood zone
Whether you're in FEMA-designated zone X (low risk) versus AE or VE (high risk) makes thousands per year of difference in insurance costs.
Walkability to downtown
The closer to the historic downtown DeLand core, the more premium per square foot. Walking distance to Athens Theatre or Indiana Avenue businesses commands a measurable premium.
Lot size and trees
Mature live oaks, magnolias, and well-established landscaping add value in DeLand specifically. Mature trees take 30+ years to grow and can't be quickly replicated.
Assessed value vs. market value
Volusia County's property appraiser sets your assessed value annually. This is for property tax purposes only. It's almost always lower than market value, especially if you've owned the home for a while and benefit from Florida's Save Our Homes cap.
It's not unusual to see a home assessed at $325,000 with a true market value of $475,000. The county isn't trying to be sneaky — they're following statutory rules for assessment. Just don't confuse this number with what your home will sell for.
Appraised value vs. market value
An appraiser is a licensed professional who provides a formal valuation, usually for a specific purpose (mortgage, refinance, estate, divorce). Their methodology is similar to a CMA but more rigid and conservative, because they're providing a number a lender will lend against.
Appraised values often come in slightly under market value, especially in rising markets. This is why appraisal gaps are sometimes a thing in competitive markets.
How we approach valuations at Monarch
When you request a valuation from us — through our CMA form on the home page, or by calling — here's what we actually do:
- We pull the last 90 days of closed sales in your specific neighborhood from the Stellar MLS
- We pull current active listings competing with yours
- We pull pending sales for the freshest market signal
- We look at your home's specifics: square footage, bedrooms, baths, year built, lot size, special features, condition based on what we can see
- We adjust the comps to align with your home's specifics
- We layer in our local knowledge: which streets command premium, which HOAs are selling well, what's coming online soon that might compete
- We give you a range, not a single number — most homes have a list-price range of about $20k–$40k where they could reasonably sell
- We talk through pricing strategy: where in that range you should list to maximize either speed or final price, depending on your goal
The whole process takes us a few hours of work. We do it for free for sellers considering listing with us, and we'll do it for buyers trying to evaluate an offer too.
