Issue 02 / AboutFounded 2025 · Built for operators

The arbitrage market is broken. We're rebuilding the inputs.

ArbiBase exists because every serious operator we know has the same private spreadsheet - verified landlords, vetted markets, real numbers. We turned that spreadsheet into a product.

THE PROBLEM

Arbitrage runs on whisper networks and broken inputs.

WHAT OPERATORS ACTUALLY FACE

Cold outreach roulette.

Operators send 200+ messages to find one landlord who will allow STR or MTR. Most never reply.

Stale, scraped data.

Listings that said "yes to STR" three years ago. HOA bylaws nobody actually read.

Underwriting by gut feel.

AirDNA averages, optimistic occupancy, expense lines from a YouTuber's spreadsheet.

Compliance after the fact.

Sign first. Pray the city framework doesn't change. Lose units to short-term rental bans.

WHAT WE CHANGED

Inventory is consented up front.

Every property on ArbiBase has verified landlord consent (verbal, written, or formal) for STR/MTR before listing.

Listings have an expiry.

Verifications go stale in 90 days. Re-verified or removed. No more zombie data.

Underwriting uses real comps.

Per-zip occupancy and ADR from operator-reported data - not scraped Airbnb listings.

Compliance shipped with the listing.

Each unit ships with state + city framework attached. Updated whenever the law moves.

METHODOLOGY

How a unit gets verified.

Every property on ArbiBase passes the same four-step check before it appears in inventory. There are no shortcuts and no marketing exceptions.

2–4 days

Landlord attestation

We get the owner's attestation that their property may be operated as a short-term or mid-term rental. This is obtained either verbally, in writing (SMS/email), or through our formal consent form.

1 day

HOA / building rules

Where applicable, we pull HOA bylaws and building rules and confirm STR/MTR is permitted. Buildings that prohibit it never enter our index, even if the landlord consents.

Ongoing

City + state framework

We attach the current city + state STR/MTR framework to the listing. When the framework changes - Austin, Nashville, Phoenix have all moved in 2025 — every affected listing is flagged within 48 hours.

Every 15-30 days

Expiry + re-verification

Verification expires in 15-30 days. The landlord re-attests. The framework is re-checked. If anything changes, the listing is pulled or re-priced. Stale verifications don't earn the badge.

STANDARDS

What "verified" actually means.

INVENTORY

Verified ≠ guaranteed.

Verified means the landlord has consented and the property is legally cleared. You still negotiate and sign your own lease. We don't broker.

NUMBERS

Operator-reported, not scraped.

Our occupancy and ADR comps come from operators on our platform reporting actual revenue — not from scraping public listings.

COVERAGE

We say 'no' a lot.

About 1 in 4 properties submitted clears all four steps. The rest don't ship. We'd rather have a small honest index than a big dirty one.

CONFLICTS

We don't take landlord fees.

ArbiBase is operator-side only. Landlords don't pay to list. Removing the conflict is the only way verification holds up.

FROM THE FOUNDER

Why ArbiBase exists.

"We've walked away from a lot of listings to keep the index clean. We'd do it again. An index you can't trust is just a prettier Craigslist."

Every serious operator we know maintains a private spreadsheet — verified landlords, vetted markets, real numbers. The problem is that spreadsheet never scales. It took us 18 months of cold outreach, dead leads, and compliance surprises to build ours. We built ArbiBase so no operator has to repeat that process.

The arbitrage market doesn't have a demand problem. It has a trust problem. Operators can't find verified inventory. Landlords can't find vetted operators. Coaches can't point students to real deals. We're solving all three at the same time because they're the same problem.

We don't scrape listings. We don't fake verification. Every property on this platform has documented landlord consent, confirmed STR/MTR eligibility, and an active compliance check. When something changes, the listing gets flagged or pulled. That's it.

Verification has an expiry.

Nothing stays "verified" forever. Consent and compliance are re-checked every 15–30 days. Stale data gets pulled.

We never take landlord fees.

ArbiBase is operator-side only. Removing the conflict of interest is the only way verification stays honest.

We say no more than yes.

About 1 in 4 submitted properties clears all steps. A small clean index beats a large dirty one.

Operators own their data.

Your underwriting, your cashflow, your deals. We never share operator data with landlords or competitors.
