The Real Cost of Owning Property in San Juan

Why 'All-In' Looks Different Here Than on the Mainland

San Juan doesn't carry a state income tax, a mainland-style county appraisal district, or a standard NFIP-plus-private-carrier insurance stack the way a US coastal county does -- it runs on Puerto Rico's own tax code, its own property-assessment agency (CRIM), and an electric grid that has been a national news story since 2017. None of that makes ownership here unaffordable by definition, but it does mean a mainland buyer's mental model for 'carrying costs' needs real adjustment, not just a currency-free assumption that the rules are the same.

This page focuses on the costs that are structurally different from a US state -- property tax, sales tax, insurance deductibles, and grid reliability -- rather than repeating a generic homeownership cost checklist that would apply anywhere.

Purchase Price: A Market Act 60 Has Reshaped

San Juan's median listing price has been cited around $895,000 to $905,000 across recent market snapshots, with real variation by source and date. Condado, the city's luxury beachfront benchmark, runs a neighborhood median near $1.8 million and roughly $790 per square foot. Old San Juan, constrained by its historic-district building stock and limited inventory, has shown sales ranging from $401,000 to $3.8 million with a median sale price around $1.3 million and roughly $581-$598 per square foot. These figures reflect a market that has moved meaningfully in a short window: one estimate put San Juan housing-cost growth at more than 60% between 2021 and 2023, and separate reporting found median prices in Condado, Dorado, and Palmas del Mar up 38% to 65% since 2020 -- both driven substantially by relocation under Puerto Rico's Act 60 tax-incentive program, covered in depth on this site's Vacation Rental Investment and What Nobody Tells You pages.

That price movement sits against a genuinely low local median income -- one 2023 estimate put average San Juan income around $25,621, a wide gap from a roughly $900,000 median listing price. This page states that gap as a documented, sourced fact about the market's current character, not a value judgment about any individual buyer's decision.

CRIM Property Tax: Assessed on 1957 Values, Not Market Value

Puerto Rico's real property tax is administered by CRIM (Centro de Recaudación de Ingresos Municipales), the central collection agency for all 78 municipalities. CRIM's assessed value is not tied to a property's current market value or purchase price -- it's built on a base-value methodology anchored to 1957 property valuations, with adjustments, and multiple guides describe the resulting assessed value as often representing roughly 40% to 50% of a property's acquisition cost. Municipalities then apply their own millage rate against that assessed base, generally cited in the 8.03% to 11.83% range. The combination of an antiquated valuation base and a percentage-style millage against that base routinely produces an actual annual bill that is a small fraction of what a mainland buyer would expect from a comparably priced coastal property -- but this page does not state a specific dollar figure for any given home, since the real number depends entirely on that property's own CRIM assessment history, which a buyer should pull directly rather than estimate.

A primary-residence exemption (exoneración contributiva) of up to $15,000 of assessed value is available for one dwelling per taxpayer, up to one cuerda of land, filed on Form AS-38 within 30 days of acquisition (or by January 1 following purchase for an already-registered property). This site's Property Tax Guide covers CRIM's mechanics in full detail, including what this page could not confirm about appeal processes and current-year assessment cycles.

IVU Sales Tax: 11.5% Combined, With Real Exceptions

Puerto Rico's combined sales-and-use tax (IVU: Impuesto sobre Ventas y Uso) has run at 11.5% since 2015 -- a 10.5% commonwealth rate plus a 1% municipal rate. This applies broadly to goods and most services, but with real carve-outs a buyer should know: eligible prepared restaurant food is taxed at a reduced 7%, and certain professional services carry a reduced 4% rate. IVU is a real, recurring cost on furnishing a home, on renovation materials and contracted labor, and on day-to-day living here -- it's meaningfully higher than most mainland state sales tax rates, and it's worth budgeting explicitly rather than assuming a mainland-typical 6-8% rate applies.

Insurance: A Percentage Deductible, Not a Flat Number

General insurance-industry guidance describes Puerto Rico hurricane and windstorm coverage as carrying a percentage-based deductible rather than a flat dollar amount -- commonly cited at 2% of the insured limit for concrete-construction residences and 5% for wood or mixed-construction residences. That distinction matters directly in San Juan, where most housing stock, particularly in Old San Juan and Condado's mid-rise and high-rise towers, is concrete construction. On a $900,000 policy, a 2% deductible works out to $18,000 of out-of-pocket exposure before a wind claim pays -- a real number worth running against your own coverage amount rather than assuming a flat $1,000-$2,500 mainland-style deductible applies. This page did not find an independently confirmed current average premium for a San Juan property, and this site's Coastal Insurance Explained page covers what could and couldn't be verified about the broader insurance market in more depth.

The Generator Question: A Real, Recurring Line Item

This is the cost category that most distinguishes San Juan from every other market on this site: grid reliability has been enough of a documented, ongoing problem since Hurricane Maria's 2017 landfall -- and since LUMA Energy took over transmission and distribution in June 2021 -- that many owners and businesses budget for a standby or portable generator as close to a necessity as a discretionary purchase. Multiple sources describe power-outage frequency increasing meaningfully since the LUMA takeover, including a documented estimate of roughly nineteen outages per household in 2024 alone, and single events affecting hundreds of thousands to more than a million customers at once (a June 2024 outage affected more than 350,000 customers; an April 2025 outage during Holy Week affected all 1.4 million of LUMA's customers). This page did not find independently confirmed current generator-installation pricing specific to San Juan, but treats the underlying need as a real, sourced cost category rather than an alarmist add-on -- covered in more depth on this site's Storm Prep Costs and Hurricane & Storm Risk pages.

Adding It Up: A Framework, Not a Guaranteed Number

There is no single verified 'true cost of ownership' figure this page states as fact, because the largest variable line items -- an individual property's CRIM assessed value, its specific insurance premium, and whether an owner adds generator or battery backup infrastructure -- depend entirely on the specific property and owner decisions. What can be said with sourced confidence: expect a CRIM property tax bill that is typically a small fraction of a comparably priced mainland coastal property's bill, because of the 1957 assessment-base methodology; expect an 11.5% sales tax on most purchases; expect a percentage-based hurricane deductible (roughly 2% for concrete, 5% for wood/mixed construction, per general guidance) rather than a flat dollar figure; and expect grid reliability to be a real, ongoing planning factor that many owners address with generator or battery infrastructure rather than treating as background risk.

Before making an offer, pull the property's actual current CRIM assessed value and tax history directly from CRIM, get real insurance quotes from a Puerto Rico-licensed broker, and ask a San Juan-focused buyer's agent or notario about typical carrying costs for the specific building or neighborhood you're considering -- condo association fees in particular vary widely and are not covered by CRIM or insurance figures alone.
