Airbnb rental arbitrage lives or dies on one decision: which listing you call about first. Most of the work of a good deal happens before you ever run the numbers - in how you filter the flood of long-term rental listings down to the handful worth underwriting. Here's the checklist to run before you pick up the phone.
1. Rule out anything that can't legally be subleased
Start here, because it's the fastest disqualifier. A great rent-to-revenue spread on a listing you can't actually operate is worth nothing.
- Check the building type. Condos and HOA-governed buildings frequently prohibit short-term rentals outright in their bylaws, independent of what the city allows.
- Check local STR ordinances. Many cities cap the number of nights, require a separate STR permit, or ban non-owner-occupied short-term rentals in residential zones entirely. This varies block by block in some markets, not just city by city.
- Ask the landlord directly about subleasing before signing anything, and get any approval in writing. A verbal yes from a leasing agent is not a defense against a lease clause that says otherwise.
2. Look for landlord-friendly ownership structure
Individual landlords and small local property managers are generally more open to negotiating arbitrage-friendly lease terms than large institutional management companies, which tend to run standardized leases with blanket sublease bans and little room to negotiate. Corporate-owned buildings can still work, but expect a slower approval process and less flexibility on lease length.
3. Match the unit to real short-term demand, not just low rent
A cheap lease in a market with no short-term rental demand is not a deal - it's a vacancy waiting to happen. Before you get attached to a listing, sanity-check:
- Is there actual Airbnb/STR demand in this specific neighborhood, not just the metro area broadly?
- Does the unit's size and layout match what that market's short-term guests actually book (a 3-bedroom in a market dominated by studio and 1-bedroom demand is a much harder rent)?
- Is the building/neighborhood one guests would feel safe and welcome in - proximity to transit, walkability, and area safety all affect both booking rate and nightly price.
4. Underwrite the lease terms, not just the rent
The monthly rent is one input. Before committing capital, get clear answers on:
- Security deposit and first/last month due at signing - this is often the largest cash outlay before you've booked a single guest.
- Furnishing responsibility. Is the unit offered furnished, or are you furnishing it from scratch? Furnishing costs can meaningfully change your break-even timeline.
- Lease length and renewal terms. A 12-month lease gives you a full year to recoup setup costs; anything shorter compresses your payback window and raises your risk if the market softens.
- Utilities and internet - who pays, and is the unit already wired for the connectivity STR guests expect?
5. Get the landlord's real objection before you negotiate
When a landlord hesitates on subleasing, it's rarely really about the money - it's almost always about risk: noise complaints from neighbors, property damage, or liability if something goes wrong. Address that directly: offer a professional operating agreement, proof of short-term-rental insurance, and a clear point of contact for issues. Landlords who've been burned by a bad tenant respond better to risk mitigation than to a higher offer.
The takeaway
The listings worth calling about are the ones that clear all five filters before you've done any financial modeling: legally subleaseable, a flexible landlord, real short-term demand for that specific unit, lease terms that don't eat your runway, and a landlord conversation that addresses risk head-on. Everything after that is underwriting math - and that's the part worth automating.
