The foundation of every successful Florida property tax appeal is comparable sales evidence — recent sales of similar properties that sold for less than your assessed value. Understanding how to find strong comparables, what makes a comp valid, and how to present the evidence is the difference between a reduction and a denial. This guide walks through the entire comparable sales process so you know exactly what to gather before your TRIM notice deadline.
Where to Find Florida Comparable Sales
Florida's property records are among the most transparent in the nation. Several free sources provide access to recent sales data that can be used in a VAB petition.
- ✓County Property Appraiser website: Every Florida county appraiser publishes searchable sales data. Search by neighborhood, subdivision, or proximity to your address.
- ✓Zillow: 'Recently Sold' filter shows sales within the past 1-2 years. Use the map view to find nearby sales.
- ✓Redfin: Strong sold data with detailed property characteristics. Can filter by bedroom count, square footage, and date range.
- ✓Realtor.com: Another solid sold data source with neighborhood filter options.
- ✓Public records: Florida Statute §28.222 gives all citizens access to recorded real estate transfers at the county clerk's office.
- ✓MLS (through a realtor): If you have a realtor relationship, they can pull precise MLS comps — the strongest comparable data available.
What Makes a Comparable Sale Valid
Not every nearby sale makes a valid comparable. The property appraiser's office and the special magistrate reviewing your petition will scrutinize your comps for validity. A comparable sale is strong when it shares key characteristics with your property and sold close in time to the assessment date.
- ✓Location: Same subdivision, neighborhood, or zip code. Cross-subdivision comps can be dismissed as representing a different market.
- ✓Time: Sales within 12 months before January 1, 2026 are strongest. Sales older than 18 months are significantly weaker.
- ✓Size: Within 15-20% of your square footage. Larger differences require explanation and adjustment.
- ✓Type: Same property type — single-family vs. condo vs. townhome. Do not mix types.
- ✓Condition: Similar condition level. If the comp is renovated and your home is original, note the difference.
- ✓Arm's-length: Avoid distressed sales (foreclosures, estates, divorce) that may have sold below market. The appraiser will flag these.
Making Adjustments to Comparables
No two properties are identical. When your comps differ from your property in specific ways, you make adjustments to reflect those differences. Adjustments bring the sale price of the comparable up or down to what it would have sold for if it were identical to your home. The goal is to produce an adjusted sale price for each comparable that represents the market value of your property.
- ✓Square footage adjustment: +/- per square foot based on the price difference for size in your market
- ✓Lot size adjustment: Relevant for properties with significant lot size differences
- ✓Pool: A pool typically adds $20,000-$40,000 in Florida markets — if comp has pool and you do not, adjust down
- ✓Garage: Covered parking is valued; adjust for presence or absence
- ✓Condition: Renovated vs. original can be a $20,000-$50,000+ adjustment depending on scope
- ✓View/location: Waterfront, golf course, or green belt premiums require adjustment if your comp has one and you do not
How Many Comparables Do You Need?
Three to five strong, properly adjusted comparables is the target for a VAB petition. Three well-matched, recent, nearby sales are more persuasive than six weak or distant comps. Quality matters more than quantity. If you cannot find three strong comparables, use what you have and explain why the market has limited data — scarcity of comps is itself evidence that mass appraisal is less reliable for your property.

Frequently Asked Questions
Where can I find comparable sales for my Florida property tax appeal? ▾
Florida county property appraiser websites, Zillow, Redfin, and Realtor.com all provide recent sale data. Filter by your subdivision or neighborhood, same property type, and sales within the past 12-18 months.
How recent do comparable sales need to be? ▾
Sales within 12 months before January 1, 2026 are strongest. Sales from 12-18 months before are acceptable with explanation. Sales older than 18 months are generally too stale to carry significant weight.
Can I use a sale from a different neighborhood as a comparable? ▾
It weakens your case significantly. The special magistrate and property appraiser will argue that different neighborhoods represent different markets. Same subdivision or neighborhood sales are far more persuasive.
Should I include distressed sales (foreclosures, estates)? ▾
Generally no. The property appraiser will argue these sales represent below-market distressed transactions and are not arm's-length. Focus on conventional, arm's-length sales between willing buyers and sellers.
What if I cannot find any comparable sales in my neighborhood? ▾
Limited sales is itself strong evidence. Argue that the scarcity of data makes mass appraisal unreliable for your property, and use the best available comparables — widening your search to adjacent neighborhoods with an explanation of why they are relevant.
Does TaxAppeal find comparable sales for me? ▾
Yes. TaxAppeal USA analyzes comparable sales from your county appraiser records and real estate databases for your specific neighborhood. This research is included in your $89 flat fee.
