Listing description
About this home
RARE REDEVELOPMENT OPPORTUNITY ON A LARGE ST. PETERSBURG LOT! Situated on an expansive lot in an established South St.
Petersburg neighborhood, this property presents an excellent opportunity for buyers looking to renovate, reimagine, or explore future redevelopment possibilities. The existing property includes a vintage brick single-family residence and detached garage with substantial paved parking/drive area, offering a unique footprint and flexibility not commonly found in the area. The existing home and detached garage are being offered AS-IS and will likely require significant renovation if retained.
For the investor, builder, or developer, the size and configuration of the site create an opportunity to investigate alternative uses, including potential redevelopment or reconfiguration of the property, subject to verification of zoning, land-use regulations, lot-split/subdivision requirements, site-plan approval and all applicable City of St. Petersburg requirements. The property is located in an area experiencing continued investment and redevelopment, making this an especially compelling opportunity for those looking beyond the existing structure and evaluating the land and its future potential.
Buyers and their agents are encouraged to independently verify zoning, allowable density, subdivision potential, development standards, utilities, setbacks, and all other information with the City of St. Petersburg and applicable authorities.

The Messtimate™
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.
$239,112the mess$383,454
Stronger local evidence — 6 comparable closed sales within about 3 miles, closed within the last 18 months, same property type, living area within 30% of this home.
Actual list price: $340,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 60% spread on the same house — and that gap is exactly what an automated guess can't see:
Condition & updates — a 1953 home may have had its roof, kitchen, or HVAC replaced since, or not; sq ft can't see either.
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 — CDD, HOA, insurance, and seller-paid buydowns change what a buyer actually pays.
And here's what the live market is doing — which the number above ignores entirely:
1 active listing competing
For reference, this home is listed at $340,000 ($233/sq ft). The list price is the seller's asking price and is not derived from this range.
Want a property-specific review from a licensed agent? A Momentum Realty agent will do a real, free comparative market analysis — walking the home, the lot, the condition, and the live market. That's the difference between a Messtimate and a valuation.
Methodology: 1,458 sq ft × $164–$263/sq ft (interquartile band of 6 comparable closed sales within about 3 miles, last 18 months; MLS closed-sale records). Estimate for general information only; not an appraisal, valuation, or offer. Updated October 13, 2026.

🟡 Asking $233 per square foot, about 9% above the community’s $213 median. Seminole Heights Rev Sub’s 12-month median sold price per square foot is $213. MLS facts: Stellar MLS closed sales. A per-square-foot gap is context, not an appraisal; condition, lot, and view set the final number here.
50% of homes in Seminole Heights Rev Sub are owner-occupied. An estimated 50% are non-owner-occupied, including 23% held in a company or trust and 9% out-of-state owners.Why it matters: a high owner-occupied share typically means fewer rentals nearby and steadier resale demand.Source: Florida Department of Revenue 2025 assessment roll (public records), 291 homes matched.

Oct 2026 · Development
ClearView apartments complete at $1 billion Echelon City Center in St. Petersburg
The 363-unit ClearView community, with ground-floor retail, is complete within the Echelon City Center development by Third Lake Partners and Echelon. A 3rd & 3rd residential high-rise with ground-floor retail is expected to open in the first quarter of 2027.
Why it matters: New downtown apartments and walkable retail add rental inventory and amenities in central St. Petersburg. The site is about 3 miles southeast of Seminole Heights Rev Sub.
St. Pete approves temporary downtown dock for Tampa Bay ferry
The St. Petersburg City Council approved a temporary ferry dock on Bayshore Boulevard near the Vinoy in downtown St. Petersburg under a three-year contract costing about 324,200 dollars. Hubbard's Marina will operate cross bay service between downtown St. Petersburg and the Tampa Convention Center, with two vessels running year round. Service is expected to begin in October or November.
Why it matters: Establishes a temporary downtown dock and cross bay ferry connection, adding a new transit option and waterfront infrastructure serving the downtown St. Petersburg market. The site is about 3 miles southeast of Seminole Heights Rev Sub.
St. Pete advances housing plan for nine vacant city lots
The St. Petersburg City Council unanimously approved a first reading of an ordinance to place a measure on the November 3 ballot that would remove nine vacant city lots in Methodist Town from the city's Charter Park and Waterfront Map. The change would allow up to 41 units of affordable or workforce housing, with four lots planned for single family homes and five larger parcels for multifamily housing. The lots have held park designations since 1984 but have remained vacant.
Why it matters: Advances a plan to convert nine vacant city lots into new single family and multifamily housing, adding to local housing inventory. Placing the parcels on the ballot could open long dormant land for residential construction. The project is about 2 miles southeast of Seminole Heights Rev Sub, elsewhere in Pinellas County.
Blake-Related team selected to redevelop 86-acre Historic Gas Plant District
St. Petersburg selected a bid led by Blake Investment Partners, with the Related Group as co-developer, to redevelop the 86-acre Historic Gas Plant District at the Tropicana Field site. The roughly 8.1 billion dollar mixed use plan calls for more than 3,600 income-restricted residential units, a 13-acre central park, and office, retail, hotel and civic space over an estimated 20-year buildout. The developers plan to purchase about 58 acres while the city retains roughly one third.
Why it matters: Adds a large mixed use district with thousands of new residential units, a central park, and office, retail, hotel and civic space to the downtown St. Petersburg market. Redevelopment of the Tropicana Field site reshapes the surrounding property landscape and expands housing supply. The site is about 3 miles south of Seminole Heights Rev Sub.

Frequently asked questions
How big is 1834 21St Street and when was it built?
Per the listing record, 1834 21St Street was built in 1953 and has 1,458 sq ft of living area, 3 bedrooms and 1.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 1834 21St Street in?
1834 21St Street is in Seminole Heights Rev Sub in St Petersburg, Pinellas County. The comparable-sales section on this page shows recent closed sales nearby from the same MLS data.
Does 1834 21St Street have an HOA?
The listing reports no HOA. Confirm with the county record that no deed restrictions or mandatory association apply to the parcel.
Why might property taxes on 1834 21St Street differ from the current owner's?
The estimate on this page (about $3,570 per year) assumes reassessment at the list price less the homestead exemption. 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 1834 21St Street 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.

Opinion & estimate — do not rely on this page. Any figure on this page that is not a verbatim fact from the listing or a public record — including estimated property taxes, insurance, CDD/HOA amounts, mortgage payments, comparable-sales summaries, and market statistics — is an opinion and estimate provided for general informational purposes only.

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.
