The engines working for you
This is not a portal with pretty pictures: it is the analysis machinery funds use, aimed at the Puerto Rico market.
Demand prediction by municipality
Where the market is moving NOW: sales volume, price per sq ft, days on market and trend, computed from real closed sales in PR, municipality by municipality.
See live demand1, 3, 5 and 10-year appreciation projection
What the property could be worth tomorrow, projected from its area's real appreciation, not a made-up number. With an amortization table to see your equity year by year.
Try it on a propertyRisks before you sign
Flood (FEMA), seismic (USGS), hurricanes and heat: all 78 municipalities analyzed. The risk the seller isn't going to mention, on your screen before the offer.
How it worksFair price from closed comparables
Every property checked against real sales in its area: you know if it's overpriced, fair or an opportunity, with the sales that prove it, not the price the owner is asking.
See analyzed propertiesAirbnb analysis by exact address
Estimated rate and occupancy for THAT address, with nearby comparable rentals, plus your break-even point, safety margin and the regulatory read (room tax, zoning). Free, and compared against long-term rent in the area.
Analyze a property as an AirbnbShort-term market pulse
PR tourism's verified numbers: revenue, occupancy and rates by region, with the source cited, inside every analysis. You know whether the market a headline sells you is the one that exists.
See the guide with the numbersFor the diaspora looking at PR
Everybody hunts the same beach property.
The winner is the one who specializes.
Diaspora demand piles onto the same coastal properties, and that compresses returns. The Airbnb that works in 2026 does not compete on location: it competes on experience, the coffee farm, the river house, the mountain refuge with a story.
Smarlin lets you find that play: the Airbnb analysis gives you estimated rate and occupancy for the exact address, with nearby comparables and the regulatory read included, and the demand score tells you which municipalities are moving before the price says so.
New: land intelligence
Investing in land? Know the parcel before anyone else.
Official Planning Board classification, real size in cuerdas, risks and estimated value from area sales, with just the catastro number.
Analyze a parcelLet's be straight
A good deal in Puerto Rico can't be spotted from a spreadsheet in Orlando. Smarlin reads every municipality with measured data, appreciation from real sales, asking rents, demand, Airbnb with market numbers, and tells you if the deal holds up for YOUR goal, counter-signals included.
The engines working for you
It's not magic or marketing: each one measures something concrete, with its source, and here is what it solves for you.
Smarlin Decision Read
Every engine's output condensed into ONE read: what this property is for you, the good, the bad, and what changed since you last looked.
How it measures it: Synthesizes fair price, velocity, risks and your own goal (saved in your profile). Every analysis is archived and versioned: if something material changes, it tells you.
The watch works alone: if a property you follow drops in price or its read changes, you know.

Try itWhy Smarlin is different
Measured data, with the source named
Real closed sales, FEMA, USGS, the Planning Board, HUD/FHA, the FHFA. Every analysis tells you where the number came from, no inflated projections or estimates from algorithms that don't know the island.
Built for Puerto Rico
Catastro, CRIM, local housing programs, room tax, all 78 municipalities. Mainland portals treat PR like just another state; Smarlin is built from the island.
Honest by design
If there aren't enough comparables, it says so. If a legal rule isn't verified, it isn't claimed. Every analysis includes what it's missing and one thing to verify, because deciding on smoke gets expensive.
The one who buys with data beats the one who buys on faith.
