Property taxes
✓ Based on certified county tax rollMany first-time Florida buyers are surprised when property taxes jump after closing. This estimate helps you budget before you make an offer.
Most of this comes from Florida’s Save Our Homes assessment cap resetting when the home sells — the current owner’s protected assessment doesn’t transfer to a new buyer.

Data is deemed reliable but is not guaranteed by the MLS to be accurate.The Messtimate
This is a deliberately dumb estimate — living area times a range of recent neighborhood $/sq ft, and nothing else. It is not an appraisal, not market value, and not a valuation of this home. Even a tight range from comparable sales can’t price a specific home — here’s why.
Actual list price: $445,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 18% spread on the same house — and that gap is exactly what an automated guess can't see:
- Condition & updates — a renovated kitchen or new roof vs. dated finishes can swing value six figures; sq ft can't see it.
- The lot & views — a premium golf, water, or preserve lot vs. a road-facing one: same sq ft, very different price.
- Outliers skew it — the band above comes from 6 nearby sales; one flip or distressed sale moves the whole $/sq ft.
- Carrying costs & concessions — this home carries HOA dues of $354/mo; with insurance and any seller-paid buydown, that changes what a buyer actually pays, and a sq ft estimate ignores all of it.
And here's what the live market is doing — which the number above ignores entirely:
- This home: 14 days on market vs. a 106-day community median
- 10 active listings competing, 1 under contract
- ≈6.0 months of supply
- 22 closed here in the last 12 months
For reference, this home is listed at $445,000 ($224/sq ft) — a number set with analysis a Messtimate can't do.

Buyer research checklist
Items worth confirming for 817 Greybull Run, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 2014: confirm the roof and HVAC install dates and whether any builder or manufacturer warranty transfers.
- HOA dues are listed at $354/mo: request the current budget, reserves, and rules before relying on that figure or on any restriction.
- FEMA flood zone X: flood insurance is not usually required, but get a quote anyway — FEMA reports roughly one in four flood claims come from outside high-risk zones.
- Get a homeowners insurance quote for this specific address in Seminole County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Listed living area is 1,989 sq ft: verify it against the property appraiser's record and measure before relying on it.
- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.
- Property taxes: the estimate on this page (about $4,672/yr) assumes reassessment at the list price; the seller's homestead cap does not transfer, so their current bill is not a guide.
- School zoning shown here comes from district data and changes; confirm the assigned schools directly with the district before relying on them.

Frequently asked questions
How big is 817 Greybull Run and when was it built?
Per the listing record, 817 Greybull Run was built in 2014 and has 1,989 sq ft of living area, 3 bedrooms and 3.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 817 Greybull Run in?
817 Greybull Run is in Grande Oaks At Heathrow in Lake Mary, Seminole County. The community section on this page shows recent closed sales, days on market, and active inventory for Grande Oaks At Heathrow from the same MLS data.
Does 817 Greybull Run have an HOA, and how much are the dues?
The listing reports HOA dues of $354 per month. Dues, what they cover, and the community's rules should be confirmed from the association's current documents before relying on them.
Why might property taxes on 817 Greybull Run differ from the current owner's?
The estimate on this page (about $4,672 per year) assumes reassessment at the list price. Florida's Save Our Homes rule caps annual assessment increases for homesteaded owners, and the assessment resets after a sale, so a new owner's bill may differ from the seller's. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 817 Greybull Run in a flood zone?
The FEMA flood map places this parcel in Zone X, outside the special flood hazard area, so flood insurance is not usually required by a lender. It is still available and worth quoting; confirm the parcel's status with FEMA and your insurer.
Can I rely on the figures on this page?
No. Estimated taxes, insurance, payments, and any market or comparable-sales summary are opinions and estimates for general information only and should not be relied upon. Verify all information independently before making any decision.
