You find rental arbitrage properties by filtering before you pitch: rule out every unit that can never work legally (zoning and short-term-rental ordinance, owner-occupancy rules, HOA or condo bans, buildings whose standard lease forbids subletting), target the owner types who say yes most often, build the lead list from county assessor and recorder records plus city rental registries and listing sites, pre-qualify each unit against your own operating requirements, and only then sequence the outreach. The property disqualifies more deals than the pitch ever will.

Most people starting in arbitrage write a landlord script first and then go hunting for somebody to read it to. That order burns weeks. You end up calling listings that were never eligible — wrong zone, wrong building rules, wrong lease form, wrong owner. Every "no" looks like a pitch problem when it was a property problem.
I have spent more than 18 years in real estate, have focused on short-term rentals since 2016, and have trained over 10,000 operators through CashFlow Diary. The operators who sign leases fastest are almost never the best talkers. They are the ones who show up with a short list of units that already cleared the rules, already fit their nightly-rate math, and already belong to an owner with a reason to move. This article is the sourcing work that happens before the first call. It is educational, not legal or tax advice — confirm your local ordinance and your lease language with a local attorney.
Why the property disqualifies more deals than the pitch
A pitch only works on a unit that can structurally support what you are asking for. If the address sits in a zone where rentals under 30 days are banned, no liability packet changes that. If the building's standard lease bans subletting and the owner uses a management company's form, the owner often cannot say yes even when they want to.
Cold-calling every listing in a market treats all properties as equally likely. They are not. A small set of property situations and owner situations produces most of the signed leases. Those situations are findable with a repeatable search.
There is a second cost to skipping sourcing: bad feedback. If you call 40 unqualified owners and hear 40 nos, you will rewrite your script when the script was fine. Filtering first gives you clean signal. When a qualified owner still says no, that answer is worth something.
Who this is not for: if you have not priced comparable listings in the target market, do not start sourcing yet. Sourcing assumes you already know what a two-bedroom near your demand driver earns on a normal month. Without that, you cannot pre-qualify anything, and you will sign a lease you cannot cover.
The five-step sourcing process
Work these in order. Each step is a filter, and each one is cheaper than the step after it. The goal is a ranked list of 10 to 20 addresses, not a spreadsheet of 400.
Step 1 — Rule out the units that can never work
Before you look at a single listing, establish the deal-killers for your market.
Start with the city or county short-term-rental ordinance and licensing page. Read the actual rule, not a blog's "STR-friendly city" label. Cities like Austin and Nashville publish their permit types, zoning restrictions, and application requirements directly; most other cities follow a similar structure. What you are looking for: which permit types exist, whether non-owner-occupied operation is allowed at all, whether there is a cap or a density limit per block, and which zones are excluded.
Check the owner-occupancy language before anything else, because it decides whether arbitrage is legal in that market at all. Some cities license short-term rentals only in the host's own home: Denver, for one, requires the property being rented to be the host's primary residence, and states that a person can have only one primary residence. An ordinance like that closes the market to a non-owner-occupied sublease. Many other ordinances issue a cheap, easy permit for a room or unit in a home the owner lives in, and a separate, restricted, sometimes capped permit for everything else. Arbitrage lives entirely in that second category. If your market only issues owner-occupied permits, you are done in that market — move on rather than arguing with it. If you are still choosing where to work, start with how to choose your first STR market instead of sourcing addresses.
Next, HOA and condo declarations. A landlord agreeing to your terms does not override a bylaw banning rentals under 30 days. For condos, assume a restriction exists until you read the declaration. For a single-family home inside a platted subdivision, assume an association exists until the recorded documents say otherwise.
Finally, the lease form. Buildings owned by institutional landlords or run by large management companies use a standard lease with a no-sublet clause and no authority at the leasing-desk level to change it. You can spot these by the branded leasing portal, the application fee flow, and the fact that nobody will give you the owner's name.
Do this work once per market and keep it on file. You are not re-researching zoning for every address; you are filtering a market you already understand.
Step 2 — Target the owner types who say yes
Owner situation predicts conversion better than any search filter you can set on a listing site. The profiles below are the ones I see convert repeatedly.
Owner type | Why they say yes | How to spot them | Priority |
|---|
Small private landlord, 1-4 units | Feels every vacant month personally; reachable directly | Owner name is a person, not an LLC, in assessor records | High |
2-20 unit owner who self-manages | Management fatigue on at least one unit | Same owner name on several parcels in the county file | High |
Long-vacancy listing (45+ days) | Already absorbing lost rent; open to unusual terms | Listing-site days-on-market filter; repeated relist | High |
Tired landlord after a bad tenancy | Wants a corporate counterparty, not another applicant | Recent eviction filing in recorder or court index | Medium |
Corporate-housing-friendly building | Already accepts 30+ day furnished stays | Building markets "furnished" or "corporate" units | Medium |
Institutional owner or large PM company | Rarely can approve a sublease at all | Branded leasing portal, no owner contact | Skip |
Two notes on that table. "Tired landlord" is a situation, not a personality — it means the owner has recently had a costly problem and is weighing a different structure. And the corporate-housing angle matters more than most beginners think: a building already comfortable with 30-day furnished stays has already solved the internal objections you would otherwise have to argue through.
Step 3 — Build the lead list from public data, not just listing sites
Listing sites show what is actively marketed. That is a fraction of what a landlord would make available to the right conversation. Use four sources together.
County assessor records. Nearly every county publishes an online parcel search — Los Angeles County's assessor portal and Harris County's appraisal district site are typical examples of what the free tier looks like. The field that matters is the owner's mailing address. When it differs from the property address, you have an absentee owner. When the same owner name appears on several parcels, you have a small portfolio owner.
County recorder records. The recorder holds deeds, mortgages, and lien filings. Recent deed transfers tell you who just bought and may not have a tenant yet. Mortgage records tell you loan type, which matters because owner-occupancy conditions on some government-backed loans complicate a full-unit sublease.
City rental registries and licensing databases. Many cities require rental units to be registered, and many publish that registry or a short-term-rental license list. That gives you two things: a roster of landlords who already operate legally, and a list of addresses that already hold an STR license — which removes your largest unknown.
Permit databases. Building-permit records show owners who recently spent money on a unit. An owner who just finished a renovation wants it occupied and often wants it occupied by someone who will not undo the work.
Then layer the listing sites on top: set a days-on-market threshold, watch for price reductions and relists, and note listings that keep reappearing with new photos. Cross-reference those addresses against your assessor pull. An absentee owner with a 60-day vacancy is your best call of the week.
For market-level context rather than address-level context, the Census Bureau's Housing Vacancy Survey publishes rental vacancy rates by region and metro. High vacancy means more motivated owners and softer rents; low vacancy means fewer conversations and less negotiating room. Use it to decide where to spend a month, not which door to knock.
Step 4 — Pre-qualify each unit against your operating requirements
Landlord willingness is only half the question. The other half is whether you want the unit at all. Score every candidate before it enters the call list.
Requirement | Pass condition | Why it kills the deal if it fails |
|---|
Layout | Bedroom count and bath access match the rate math for that submarket | A one-bath three-bedroom prices like a two-bedroom |
Parking | Dedicated space or reliable free street parking | Parking you cannot promise shows up in reviews you cannot fix |
Furnishings allowed | Lease permits furnishing and storage | Unfurnished-only kills the entire model |
Utilities | You control accounts, or the cap is in writing | Uncapped owner-paid utilities becomes a dispute by month three |
Insurance | You can bind a policy naming the owner as additional insured | No policy, no lease signature from a careful owner |
Internet | Fiber or cable available at the address, installable in your name | Slow service at the address is not something you can retrofit later |
Turnover access | Keyless entry permitted, cleaner access allowed | Manual key handoff breaks same-day turns |
Proximity to demand | Inside the booking-search radius for your driver | Two miles out reads as "wrong area" in search filters |
Check internet availability at the specific address before anything else on that list, because it is the cheapest thing to verify and the most expensive thing to discover after signing. Check the insurance question next — call your carrier with the address and the intended use before you promise the owner coverage.
A unit that clears the owner filter but fails this table is a lease negotiation you should not spend a week on.
Step 5 — Sequence the outreach
Rank before you call. I use three columns: legal eligibility from Step 1 as pass/fail, owner-situation fit from Step 2 as a count of matching profiles, and operating fit from Step 4 as pass/fail with the failed rows listed. Everything that fails either pass/fail column comes off the list entirely. What remains gets sorted by owner-situation count.
Call the top ten this week. Hold the rest. When you reach an owner, lead with the problem you solve — vacancy, damage risk, turnover labor — not with the word "arbitrage." The landlord pitch and lease-clause walkthrough covers what to say once a qualified owner picks up. Owners who match the Step 2 profiles already know the pain you are naming.
Track three outcomes per address: reached, declined with reason, and reason category. After 20 calls you will see whether your no's cluster around lease language, insurance, or price. That tells you what to fix next, and because the list was filtered, the signal is real.
An illustration of how the filter changes the math
The numbers below are an illustration with the assumptions shown, not a documented case study or a promise of results.
Assume two operators work the same market for three weeks. Operator A pulls 40 addresses from a listing site using price and bedroom filters only, with no ordinance check and no owner-type filter. If a quarter of those are in associations that ban stays under 30 days, another quarter are managed by companies that will not alter a lease, and most of the rest are local owner-occupants with no vacancy pressure, then 40 calls might produce a handful of polite conversations and no lease.
Operator B spends one afternoon cross-referencing assessor records for out-of-state mailing addresses against a 45-plus-day vacancy filter, then removes everything that fails the ordinance check and the operating table. That leaves 12 addresses. Even at the same per-call conversion, a list where most owners are absentee and carrying a vacancy converts on a different curve than a list where almost none are.
The point is not the specific counts. It is that the sourcing afternoon replaces two weeks of calls that were never going to land, and it produces feedback you can act on.
Building a reusable market file
Once the process works in one market, it becomes a file you reuse rather than research you repeat. For each market, keep:
The ordinance summary and licensing page link, with the permit types and any cap noted, plus the date you last checked it. Rules change; recheck quarterly.
A standing assessor search for absentee mailing addresses in your target zip codes, and a second search for repeated owner names.
A saved listing-site filter for 45-plus days on market and for recent price reductions.
A short list of buildings that already allow furnished 30-plus-day stays, and a list of associations you have confirmed ban short stays, so you never research the same building twice.
A quarterly note to your local property-manager contacts asking about owners they have turned away — owners whose expectations do not match a manager's model are often a good fit for your structure.
Expect the first market to take a half day to a full day to set up. Every market after that takes less, because you already know which records to pull and what a disqualifying clause looks like.
One more discipline: write down why you removed each address. Six months later, when an ordinance changes or a building sells, that file tells you which dozen units just became eligible. That is a list nobody else in your market has.

Frequently Asked Questions
How many properties should be on my list before I start calling?
Enough qualified candidates to make 15 to 20 real outreach attempts. There is no universal number, because it depends on how many units survive the ordinance, association, and lease-form filters in your market. If fewer than ten addresses clear those filters across your whole target area, that is information about the market, not about your list-building.
Do I need to pay for a property data service instead of using free county records?
No. Free assessor and recorder portals are usually enough to identify absentee owners by comparing the owner mailing address to the property address, and to spot owners holding several parcels. Paid aggregators save time across many counties at once, but they are not required to run this process in a single market.
How do I check whether a building's HOA bans short stays?
Ask the owner for the declaration and rules, and read the rental section yourself rather than accepting a verbal answer. For condos, the declaration is usually recorded with the county recorder and searchable by parcel. If the association requires board approval of tenants, treat that as a hard filter until you have written confirmation.
Should I avoid large property management companies entirely?
For units they manage, mostly yes — they rarely have authority to approve a sublease structure. They are still worth one call per quarter as a referral channel, because they turn away owners whose expectations do not fit their model, and those owners are exactly your Step 2 profile.
Does this process work for mid-term or corporate housing instead of nightly rentals?
Yes, and it is often easier. Many short-term-rental ordinances apply only to stays under a set length — commonly 30 days — so a mid-term structure can sit outside the rule that blocks Step 1. Read your own city's definition rather than assuming the 30-day line. The owner-type and operating-requirement steps stay the same. Confirm how your state's landlord-tenant law treats stays of that length before you sign anything, and treat this as educational rather than legal advice.
