Renting vs buying in St. Petersburg
St. Petersburg's typical home value is down 3.9% over the year to June 2026, on the peninsula where Hurricane Helene put the largest storm surge on record in 2024. Here is the arithmetic anyway: a Pinellas tax bill that the homestead exemption makes smaller, the two taxes Florida charges on the loan, the insurance that covers wind and not water, and the mortgage insurance that stops in the middle of the model, and then the part the arithmetic misses.
Calculator
The short answer
The typical home in the City of St. Petersburg was worth $355,759 in June 2026, down 3.9% on the year, and a three-bedroom rents for about $2,552 a month. Run those against each other at the 2% appreciation the calculator opens with and the answer turns on how long you stay and on the mortgage rate. Run them at zero, which is closer to what this bay has done since September 2024, and the break-even moves later.
The storms are the context for everything else. Hurricane Helene put the largest storm surge on record into St. Petersburg in 2024 and Milton followed two weeks later; the City assessed 13,494 parcels for damage after Helene alone. Across the Tampa Bay table, twenty-three of the twenty-four municipalities fell in value over the year to June 2026.
The tax is one published number. Pinellas County publishes 19.9197 mills for the city. A homesteaded owner pays about $6,248 a year on the typical home, 1.76% of the price, after the exemption, and a landlord about $7,087.
The calculator below opens with real City of St. Petersburg figures and every one of them is editable. Three warnings: the property tax rate is set to 1.76% of the price, the homesteaded rate, not the 19.9197 mills levied before the exemption, so if you will not live in the house, set it to 1.99%; no flood premium is included anywhere; and the appreciation default is a long-run figure rather than a description of a market that has been falling. All three are explained in the questions below.
Your situation
Compare like for like: the rent on somewhere you would actually be willing to live, not the cheapest listing in the city. Drop the price to around $300,000 and the rent to a one-bedroom figure to compare apartments instead, and put the condo fee in under Assumptions.
20.0% down. The renter starts with this plus closing costs: $75,057: invested instead.
The single biggest lever. Buying costs a lot to enter and a lot to exit, and only time amortizes that away.
Assumptions: every one of them editable
St. Petersburg's typical value is down 3.9% over the year to June 2026, and twenty-three of the twenty-four municipalities in the Tampa Bay table fell. Try zero, and try negative.
What the renter earns on the down payment they never spent. This is the comparison's hidden lever. A renter who spends it instead of investing it does far worse than this model shows.
Florida forbids its counties and cities from controlling rents at all. The statute allowed a narrow exception (a declared housing emergency, a specific finding, and a referendum) and the legislature closed even that in 2023. There is no cap, no guideline and no prospect of one, so any rent-growth figure you enter here is a forecast rather than a legal ceiling.
Roofs, furnaces, fences, hail. Averaged out it is a real cost even in the years nothing breaks.
Zero for a house with no association. On the waterfront and downtown it is a condominium market: $700 a month is a reasonable middle for a building with funded structural reserves, and an older building facing its milestone inspection, or repairing storm damage, can be far more. The fee carries the building's insurance, so ask what it covers and what the last special assessment was.

Net worth, side by side
The buyer's line is home value minus what is still owed minus the cost of selling, plus anything they invested in months when owning was cheaper. The renter's line is one portfolio: the down payment and closing costs they never spent, plus the monthly difference whenever renting is cheaper.

- The rate is fixed for the life of the loan, so there is no renewal to model, but nothing here credits you for refinancing into a lower one either.
- Neither household is credited with tax on their investments, and the buyer's gain on a principal residence is tax-free while the renter's portfolio may not be.

Questions people actually ask
Is it worth buying in St. Petersburg right now?
The typical home in the City of St. Petersburg was worth about $355,759 in June 2026, down 3.9% on the year, and a three-bedroom rents for roughly $2,552 a month. At 6.67% on a 30-year fixed loan with 20% down the mortgage alone is about $1,831 a month; add $521 of property tax and $390 of homeowners insurance and the owner's month is nearer $2,742 before a dollar of flood cover. The honest complication is what happened to this market: Hurricane Helene put the largest storm surge on record into St. Petersburg in September 2024, Milton followed two weeks later, and twenty-three of the twenty-four municipalities in the Tampa Bay table fell in value over the year to June 2026. The 2% appreciation this calculator opens with is a long-run figure, not a description of this market. Try zero, and try negative.
Why is the tax rate here 1.76% when St. Petersburg is charged 19.9197 mills?
Because of Florida's homestead exemption, not because of any assessment lag. Florida assesses at full market value and a purchase resets the assessment to what you paid. What there is instead is an exemption: $25,000 of taxable value comes off for every taxing authority, and a second slice, $25,000 in the 2024 base year and adjusted for inflation each 1 January since, comes off for all of them except the school board, which levies 6.2930 of the total in Pinellas. On a homesteaded $355,759 house that comes to about $6,248 a year, 1.76% of the price; without the exemption, which is what a landlord pays and what a buyer who never files pays, the same house owes about $7,087. The 19.9197 is the figure the Pinellas County Tax Collector publishes for the city rather than a total assembled on this site, and the City's own council sets 6.4525 of it. The exemption is not automatic: you file with the Pinellas County Property Appraiser by 1 March of the year after you buy.
What did the 2024 storms do here, and does it still matter?
It is the most important context for a purchase in this city. Hurricane Helene put the largest storm surge on record into St. Petersburg in September 2024, over six feet in the city and more than seven on the barrier islands, and flooded thousands of Pinellas homes, many of which had never flooded before. Milton followed two weeks later. The City assessed 13,494 parcels for damage after Helene and recorded 5,189 with major damage and 146 destroyed. Those are parcels, not homes, and the City publishes the layer without a description, but they put the questions in order: whether the house took water, what has been repaired since and under which permits, and what the elevation certificate says. The neighborhood guides on this site say what the City recorded in each neighborhood.
Does this include flood insurance?
No, and on this peninsula that omission is the point rather than a footnote. The $390 a month here is homeowners insurance, $4,680 a year, inside the $3,900 to $5,500 a year published for a St. Petersburg single-family house with wind cover, and homeowners insurance does not cover flood anywhere in the United States. Flood is a separate policy, priced off an elevation certificate rather than an address, and it is what actually paid for the damage in 2024. Get a flood quote on the specific property, and ask for its claims history.
What is FEMA's substantial improvement rule, and why does everyone here mention it?
Because it decides whether a damaged house near the water is a renovation or a teardown. If the cost of repairing or improving a structure reaches half its market value before the work, FEMA's definition makes it a substantial improvement, and a structure that has sustained that much damage counts whatever repair is actually done: either way the building has to be brought up to current flood standards, which on an older slab house near the bay can cost more than the house is worth. If you are buying anything that took water in 2024, the substantial damage determination and the elevation certificate are the first two documents to ask for, ahead of anything on this page.
Why is the seller's tax bill so much lower than the figure here?
Save Our Homes. A homesteaded property's assessed value may rise no more than 3% a year, or the change in the consumer price index if that is lower, for as long as the same owner keeps the exemption, and it resets to full market value on the roll after a sale. A long-tenured neighbor may be paying a fraction of what you will. If you already own a Florida homestead you can carry up to $500,000 of the accrued benefit to the new one, on its own application. And note the corollary in a falling market: your assessment resets to what you paid, so buying after a decline sets a lower base than a buyer at the peak.
What are the closing costs, and why do they get bigger if I put less down?
Florida taxes the loan as well as the house. The documentary stamp on the deed, 70 cents per $100, the standard state rate here rather than Miami-Dade's, is the seller's by convention. Yours is a second documentary stamp on the promissory note at 35 cents per $100 and a non-recurring intangible tax on the mortgage at 0.2%. On a $284,607 loan that is $1,565, and because it is charged on the borrowing rather than the price it rises as your down payment falls: at 5% down it is $1,859. With a settlement fee around $850, the buyer's title charges, an inspection at about $700 (in Florida that is really three reports, the general one plus wind mitigation and four-point, and the last two are what an insurer asks for) and the clerk's recording, the buyer's side comes to roughly $3,905 before lender fees. Near the water, add an elevation certificate.
How long do you have to stay for buying to beat renting in St. Petersburg?
Getting in costs about $3,905 before lender fees, and $1,565 of that is Florida's tax on the loan itself. Getting out costs about 6.5%: commission, the seller's 0.7% documentary stamp on the deed and the title policy, or about $23,124 on a $355,759 house. On the defaults below owning passes renting in year 29, counting the buyer's position after the cost of selling against the renter's. A stay of under five years does not pencil on these numbers. The friction alone is a shorter and different answer: at a 2% appreciation assumption those two ends take about 3.9 years to earn back. Zillow's index for the city is down 3.9% on the year, so set appreciation to zero as well and see what the answer looks like.
How much do you need for a down payment in St. Petersburg?
Legally, nothing sets a floor: this is a lender's decision rather than a rule. Conventional loans start at 3% down and FHA at 3.5%. On a $355,759 house, 3% is $10,673 and 20% is $71,152. What the low end costs you on a conventional loan is private mortgage insurance: at 3% down, about $250 a month until the balance reaches 78% of the price, which takes 12.2 years and about $36,500. At 5% down it is $189 a month and $26,000. In Florida a smaller down payment also means more tax on the loan at closing.
Does Florida have rent control?
No, and St. Petersburg is not permitted to introduce it. Florida forbids its counties and cities from controlling rents at all. The statute allowed a narrow exception (a declared housing emergency, a specific finding, and a referendum) and the legislature closed even that in 2023. There is no cap, no guideline and no prospect of one, so any rent-growth figure you enter here is a forecast rather than a legal ceiling. If you are renting long-term, set the rent-growth input above the 2% default and see what it does to the answer.
Which St. Petersburg are we talking about?
The City of St. Petersburg: the municipality whose millage and Zillow indexes every figure on this page describes. Several places with St. Petersburg around them are not in it. Gulfport, South Pasadena and Kenneth City are separate cities on its borders, each with its own total: Gulfport's is 17.4930 mills. St. Pete Beach, on the barrier island, is another, at 15.8285, and it is outside the Pinellas transit district. Lealman, north of the city, is unincorporated Pinellas County with no city levy at all. A St. Petersburg mailing address does not settle which one a house is in, and if the address you are looking at is not inside the city limits, the tax figure here is the wrong one for it. The Pinellas County Property Appraiser's record for the property says which.
What is the calculator not accounting for?
Federal tax, mainly, and it cuts both ways. Mortgage interest and property tax are deductible if you itemize, and whether itemizing beats the standard deduction depends on the household: first-year interest on the typical loan is about $18,900 and property tax about $6,248. A principal residence's gain is excluded up to $250,000 single or $500,000 married under section 121, and the renter's portfolio is not. None of that is modeled, and none of it is advice. Three St. Petersburg things it also cannot price: the flood policy; the cost of meeting FEMA's substantial improvement rule on a house that needs work; and a waterfront condominium's association fee, which carries the building's insurance and structural reserves and has been moving since the storms.
Which figures here are estimates
The prices, rents and millage above come from published sources, each one listed below with the period it describes, and the tax figure is derived from that millage through Florida's own exemption rules. These do not:
- Home insurance at $390 a month, which is the layer's surge-banded figure for a coastal Tampa Bay address and excludes flood entirely
- The association fee, at $700 a month: no authority publishes a St. Petersburg average, and the waterfront condominiums of every vintage since the 1960s are not comparable with each other or with new towers downtown
- The bedroom split of the rent figure, which applies the same 0.86 / 1.00 / 1.24 ratios as the four Florida metro layers to a single all-homes index
- The utilities an owner pays over a renter, at $150 a month
- Maintenance at 1% of the home's value a year
- Every forward-looking rate: appreciation, rent growth, cost inflation and the return on the invested difference, in a city whose typical value fell over the year to June 2026
- The private mortgage insurance rate, which is priced per borrower by credit score rather than published as a schedule
- Both the insurance and the tax rate as they apply to any particular address. These are figures for the municipality, and in a city where the City's own Helene assessments found water in thousands of homes along the bay and almost none in the neighborhoods inland, the flood exposure varies far more than the price does
If you want the payment side on its own, with the biweekly plan, prepayments, the month mortgage insurance stops and the two taxes Florida charges on the loan, the mortgage calculator covers it in more detail. To work out where rather than whether, start with the neighborhood guides, or compare the city against the other municipalities of Tampa Bay.
