Listing description
About this home
Currently operating as a successful short-term rental, this exceptional St. Johns County property offers a rare blend of privacy, space, energy efficiency, water views, and income-producing potential -- all within the home of Florida's No. 1-ranked school district.
Set on a secluded one-acre wooded homesite, the 3,470-square-foot residence is surrounded by mature trees that create a peaceful natural buffer and the feel of a private retreat. Designed for both everyday living and guest flexibility, the home features three bedrooms, four bathrooms, a dedicated office, and two versatile flex rooms that can serve as additional sleeping areas, a media room, home gym, game room, or creative workspace. Inside, soaring 10-foot ceilings, elegant tray details, abundant natural light, and tranquil water views create an inviting atmosphere throughout the home.
The thoughtful layout offers multiple gathering areas, giving owners and guests plenty of room to relax, entertain, and enjoy the property's private setting. Energy efficiency is another major advantage, with solar panels helping reduce electric costs to a reported average of approximately $30 per month. That kind of monthly savings can be especially valuable for a full-time residence, vacation home, or income-producing rental.
With its spacious floor plan, private wooded setting, water views, coastal location, and current short-term rental use, this property is well-positioned for a buyer seeking a personal retreat, vacation home, or investment opportunity in one of Northeast Florida's most desirable counties.

Estimate: asking price less the $50,000 homestead exemption × St. Johns County rate (13.47 mills, adopted 2025 millage). Not a bill.
⚠️
Property taxes in Florida are reassessed after a sale, so a buyer’s first full-year bill can be higher than the seller’s. Budget from this estimate, not the current bill, before you make an offer.
Current owner’s estimated bill $16,800/yr ($1,400/mo) — taxable value $1,246,444 × 13.47 mills
$11,625 more each year
(+69%)
The current owner’s taxable value is below today’s asking price; after a sale the assessment is set from market value, so the estimated bill is higher. Exemptions and portability can reduce it.

How it stacks up
Comparable recent sales
No closed sales of a similar home within about 10 miles in St. Johns County in the last 18 months are in our MLS data set, so this page shows no comparable-sales median or automated estimate for Diego Island. A licensed Momentum Realty agent can prepare a property-specific comparative market analysis on request.
The Messtimate™
The Messtimate
Insufficient local evidence for an automated estimate. The Messtimate is a deliberately simple range — living area × recent closed-sale $/sq ft from comparable homes nearby — and it only renders when at least 3 defensible sales exist within about 10 miles in St. Johns County in the last 18 months. None qualify for this home, so no dollar range is shown. It is not an appraisal or a valuation.
Want a property-specific value review? A licensed Momentum Realty agent can prepare a free comparative market analysis using the home, the lot, its condition, and the live market.
Methodology: the range would be 3,470 sq ft × the interquartile $/sq ft of comparable closed sales (same property type, living area within 30%, closed within 18 months, nearest verified subdivision, 3-mile, then 10-mile same-county stage). Estimate for general information only; never an appraisal, valuation, or offer. Updated October 2, 2026.

Frequently asked questions
How big is 116 DIEGO ISLAND Court and when was it built?
Per the listing record, 116 DIEGO ISLAND Court was built in 2014 and has 3,470 sq ft of living area, 3 bedrooms and 4.0 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 116 DIEGO ISLAND Court in?
116 DIEGO ISLAND Court is in Diego Island in St. Augustine, St. Johns County. Too few comparable closed sales exist nearby for this page to show local sales statistics; a licensed agent can prepare a comparative market analysis.
Does 116 DIEGO ISLAND Court have an HOA, and how much are the dues?
The listing reports HOA dues of $85 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 116 DIEGO ISLAND Court differ from the current owner's?
The estimate on this page (about $28,425 per year) assumes reassessment at the list price less the homestead exemption. Estimated buyer taxes are about $11,625 more per year than the current owner’s estimated bill (+69%). Florida reassesses a home after it sells; for a homesteaded seller the Save Our Homes cap on their assessment does not transfer, and a buyer's own exemptions and portability are applied separately, so the two bills usually differ. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 116 DIEGO ISLAND Court in a flood zone?
A flood designation has not been verified for this address. Look up the parcel on FEMA's Flood Map Service Center (msc.fema.gov) and confirm with 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.

These figures may be inaccurate or out of date, are not appraisals, valuations, or financial, legal, tax, or investment advice, and should not be relied upon. Do not make any purchase, offer, financing, or other decision based on this page. Independently verify everything — price, square footage, lot size, year built, taxes, CDD/HOA, flood status, school assignments, permits, and community rules — with the listing broker, the county, your lender, a licensed inspector, an insurer, and your own advisors before acting.
Estimate methodology. Tax estimates apply county millage to the list price (less the homestead exemption where the parcel is matched to the certified roll) and will differ from the actual assessed bill. Cost and market figures are derived from available data and simple calculations, not a professional appraisal. We make no representation that any estimate reflects fair market value.
