Comps and after-repair value, straight from the county records.

Type a Florida address. About a minute later you have comparable sales, a repair budget, the permit history the city publishes, and an offer calculator you can argue with — all of it traceable back to a public record, none of it behind a login.

Comps by Boost My Spot — the Florida county coverage map inside the tool
Why it exists

The data was always public. Getting to it took an afternoon.

Every Florida county publishes its parcel roll, and most cities publish their permits — but each one does it differently, behind its own portal, with its own search form and its own idea of what a date range means. So the sensible thing, checking three addresses before driving out, quietly turns into an evening. This reads those sources for you and prints one page.

What comes out

One page per address, six things on it.

Comparable sales

Recent arm’s-length sales near the subject, with distance, beds and baths, area, sale date, price and price per square foot. Non-market transfers are marked as such instead of quietly dragging the average down.

Repair budget

Built from county-assessed depreciation and whatever permit history the city publishes. Work that never showed up in the records is counted as never done, so the budget errs high rather than flattering the deal.

Offer calculator

ARV × MAO% − repairs − assignment fee, with every input on screen and editable. Change the percentage and the number moves while you are still looking at the comps.

Building permits

Where the city publishes them: scope, status, date and job cost. Miami goes back to 2014; several counties expose only a rolling two-year window; a few publish nothing searchable by address.

Sale history

Every recorded transfer on the parcel with dates and prices — the fastest way to see a flip that already happened, or a hold that has not moved in twenty years.

County assessment

Market, land, building and taxable value by year, straight off the appraiser roll. Useful as a sanity check when the comps disagree with each other.

Coverage

All 67 counties, in three depths.

Depth depends on what the county actually publishes, and the tool tells you which one you are looking at rather than pretending they are equal.

Live from the appraiser

Beds and baths, sales history, comps and permits: Miami-Dade, Broward, Orange, Hillsborough, Sarasota, Manatee, Lee.

Partial

Owner, lot, county value and comps where sales are published: Palm Beach, Pinellas, Brevard, Polk, Pasco, Osceola, Volusia.

Base layer

Every remaining county, from the state tax roll: parcel record, area, year built, recent sales and comps.

Who it is for

Anyone who has to decide before the weekend.

Agents

A defensible number for a listing conversation, with the sales it came from printed underneath it.

Investors and wholesalers

Screen a list of addresses in an evening instead of a week, and know which three are worth the drive.

Owners

See what the county has on your own house — the assessment history, and the permits somebody pulled before you bought it.

Contractors

Check the permit record on a property before quoting work that was supposedly already done.

What it is not

An estimate, not an appraisal.

Everything here is assembled from public county records. It is not a licensed appraisal, not a broker price opinion, and not investment advice — verify before you make an offer.

Permit depth varies by city: some publish everything since 2014 with job costs, others only a rolling two-year window, and a few publish nothing searchable by address. Repair budgets use market average unit costs, not a contractor’s bid.

Try it on an address you already know.

That is the honest test of a tool like this: run a property whose story you know, and see whether the page agrees with you. If you want the report by email it will ask once — one report, no list.
