Frequently asked questions

Straight answers, in plain English.

These are the questions we get most from city staff, county finance teams, condo property managers, and HOA board members. Everything below is what we'd tell you on a phone call — we just wrote it down so you can read it whenever it's convenient.

For cities + counties

How does cohost help our city collect the lodging tax we're owed?

We look at every short-term rental listed on Airbnb, VRBO, and Booking.com in your area and compare it to your list of registered rentals. The ones that don't match anything on your list are probably operating without registering. For each one, we estimate how much lodging tax you're missing, based on your tax rate and what the rental appears to earn.

What does it cost our city to start?

Nothing. No subscription, no setup fee, no charge per rental, and no lengthy purchasing process. We're only paid when you collect — 10% of the tax we help you recover. If you recover nothing, you pay nothing. You send us your list of registered rentals (a spreadsheet is fine) and we run the first check within 48 hours.

Can this work with the system we already use?

Yes. Today we hand you every flagged rental and the full record as a spreadsheet, so your team can drop it into whatever you use — Tyler, OpenGov, or just Excel. We're building direct connections to the major systems; tell us which one you use when we set you up.

Do you send the notices to operators yourselves?

No — we prepare the notices for you, with your rules and the tax math already filled in. Your team sends them however you do today: email, certified mail, or in person. We record how and when each one went out, so you have a complete paper trail.

Where does your information come from?

The rental listings come from a public, openly-licensed dataset of Airbnb listings. Your registered-rental list comes from your city's public records, or from a spreadsheet you send us. We never scrape Airbnb's website — we only use the public dataset.

For HOAs + condo associations

Can an HOA use cohost to enforce its rental ban?

Yes. Many condo and homeowner associations have rules against short-term rentals — sometimes stricter than the city's. We compare your list of approved rentals (or, if you ban them entirely, an empty list) against the rentals listed online in your area. Anything that doesn't match is likely breaking your rules, and we calculate the fines based on your fine schedule.

We don't have an 'approved rental' list — we ban them completely.

That's the simplest setup. We treat every rental listed in your community as a possible violation. You send us your list of units (addresses or parcel numbers), and we show you which ones are on Airbnb. Fines are figured at the daily rate in your rules.

How do you know which units are ours?

You tell us. When we set you up, you give us the list of units in your association — addresses, parcel numbers, or both. We only show you flagged rentals inside your community. We don't try to guess your boundaries.

What if a unit is registered with the city but still breaks our rules?

That happens a lot — cities are often more lenient than HOAs. We flag it clearly as 'OK with the city, but breaking your rules,' because both you and the city can enforce your own rules separately. We handle both in the same place.

Can an HOA legally enforce a rental ban against owners?

We're a software tool, not a law firm — check with your attorney about your specific rules. In general, courts have repeatedly upheld HOA rental bans when the rules are properly recorded and the board follows its own published process. We give you the evidence and the notice templates; your attorney and board handle the actual enforcement.

How it works

How do you match a rental to our records if the exact address is hidden?

Listings often hide their exact address, so we use three approaches, in order: first, the permit number — many hosts type theirs right into the listing; second, the location — if a registered rental sits within about 150 meters of the listing's map pin, that's a strong match; and third, the address itself, matched even when it's written a little differently. Every match comes with a confidence level you can see, and you can adjust how strict it is for your area.

How do you come up with the 'estimated lost tax' number?

For each unregistered rental: the nightly rate, times 365 nights, times how often it appears booked, times your lodging tax rate — and then we trim it down to stay realistic, because listings look more booked than they actually are. It's an estimate at the time of the check, not a final figure; in the first few months we fine-tune it against what you actually collect. We always show our math.

What happens when a rental disappears?

If a rental we flagged before is gone the next time we check, we mark it 'no longer listed' — often a sign the owner took it down after getting a notice. The case stays in your records; you can close it or keep it open to pursue back taxes.

How often is the data updated?

The listing data updates monthly. Your registered-rental records update on your own schedule. The dashboard always shows when each was last updated, with a simple color signal for how fresh it is — and you can refresh anytime.

Can we adjust the matching for our area?

Yes. Every city writes addresses a little differently, which can throw off matching. There's a settings page where you can make matching stricter or looser and see the effect right away. It only affects your data, no one else's.

Pricing + pilot

If it's free, how do you make money?

We take 10% of the lodging tax you collect because of cases we found — about what a traditional tax-recovery firm charges, but faster and with a full record of everything. The recovered amount is tracked in your dashboard, and we bill the 10% every quarter against it. If you collect nothing in a quarter, the bill is nothing.

What does it cost to start? Anything upfront?

Nothing. No setup fee, no subscription, no charge per rental, no purchasing process. Setup is free: we load your records, run the first check within 48 hours, and show your team how to use the dashboard. We only get paid after you collect — so we're rooting for the same outcome you are.

What's included?

Everything: full access for your whole team, regular checks against the latest listings, unlimited notices, evidence files for your case records, the quarterly recovery report, the settings tools, the connection options for your other software, and direct access to our team. No limits, no caps.

Do you carry insurance / liability protection?

Yes — we carry Errors & Omissions insurance suited to a product that serves governments. We prepare draft notices and estimates; your office sends notices under its own authority and reviews the numbers first. Nothing needs to be signed to start, since we're only paid on what you collect. If you'd like the standard insurance and indemnification language for your records, we'll provide it.

Are you FedRAMP / StateRAMP / SOC 2 certified?

Not yet. We're bootstrapped and serving our first partners; those formal certifications come as we grow a paying customer base. If your purchasing rules require a specific certification, tell us when we set you up — for many cities, the data protections and full record-keeping we already provide address the same concern.
