Thirty-eight percent.
That is the share of all rental units in the United States owned by individual investors rather than companies, according to the most recent Rental Housing Finance Survey from HUD and the Census Bureau, and among the small one-to-four-unit properties that agents actually prospect, individuals own 70 percent (HUD and Census). Those owners show up in your market in two completely different ways, and almost every guide to landlord leads mashes them together into one list called “FRBO or absentee owner, we use the terms interchangeably.”
They are not interchangeable. Not close. A for rent by owner listing is an event: a vacancy, happening now, with a phone number attached and a clock running. An absentee owner is a status: a parcel whose tax bill goes to a different address than the property, which was true last year and will be true next year. The first is a list you pull daily and work fast, like expireds. The second is a list you build once and work on a cycle, like a farm. Building them the same way wastes the urgency of one and the patience of the other.
The event list: for rent by owner
A FRBO lead is a landlord who has published a rental ad without a property manager or a leasing agent. The signal is the ad, the trigger is the vacancy, and the shelf life is the time it takes to fill the unit, which in most markets is weeks.
The ads live where tenants look. The large rental portals carry an owner-listed filter or show the contact as the owner rather than a management company. General classifieds and neighborhood marketplaces carry the small landlords the portals miss, and they are worth the extra effort because those owners are least likely to have any agent relationship at all. Local rental sites, university housing boards near campuses, and the physical sign in the yard on your way through the farm round it out. Each source needs to be checked on a schedule, because a FRBO ad that was new on Monday is a filled unit by the following Monday, and the FRBO script is built for an owner who still has the vacancy.
Three signals inside the ad are worth more than the ad itself.
The age of the listing. A rental ad that has been up for thirty days at the same price is an owner whose vacancy is costing them a second month’s mortgage, and whose confidence in doing it themselves is fading at about the rate a FSBO’s does. Sort every FRBO source by listing date and work the aged ones first.
A price reduction. The same signal with a number on it. An owner who dropped the rent has already reconsidered once.
More than one ad from the same owner. A phone number that appears on two or three rental listings belongs to a small portfolio holder, which is a different conversation from an accidental landlord, and it is one owner, not three leads.
That last point is the rule the ranking guides miss and the one that matters most for the record: the lead is the owner, not the address. One landlord with four units advertised gets one record, one call, and four properties attached to it. Calling the same person four times because a list treated each ad as a lead is how a landlord list burns out in a month.
The status list: absentee owners
An absentee owner is any parcel where the owner’s mailing address on the tax roll differs from the property address. That is the entire definition, and it makes the list free, because the county assessor already holds both fields for every parcel in the jurisdiction.
Pull the assessor export for the area you want, as the phone sourcing piece describes for a farm, and compare the mailing address to the situs address. Every mismatch is an absentee owner. That is the list. Then refine, because the raw list mixes several kinds of owner who need different treatment.
Out-of-area owners. A mailing address in another state or another metro is the classic absentee: an inherited house, a relocation where the old home was kept, a retiree’s former residence. These owners have the weakest local ties and the least ability to manage a property themselves, and they are the ones most likely to sell when the next vacancy or repair arrives.
Local owners of one other property. A mailing address across town usually means a deliberate rental purchase or a house the owner grew up in. Often a long-term hold. Worth a place on the list, and worth the annual call, and rarely a listing this year.
Owners of multiple parcels. Sort the export by mailing address. Count. An address that receives tax bills for five parcels is a portfolio, and the owner’s decision about any one property is a portfolio decision. Treat the owner as one record with five properties, and expect the conversation the landlord prospecting hub describes, about the hold-lease-sell plan across all of them rather than about one house.
Long-held, low-basis owners. The last-sale year on the tax roll tells you how long the owner has held the property. An owner who bought a rental twenty years ago is sitting on a gain and, usually, on deferred maintenance, and is the owner most likely to say “after this tenant.” They are also the owner most likely to raise the tax question, which goes to their CPA and not to you.
Entities. Parcels owned by an LLC or a trust need one more step, because the phone match on an entity name returns nothing. The registered agent for an LLC is on the secretary of state’s site, and the trustee’s name is often on the recorded deed. Sometimes the entity is a national investor and the parcel comes off the list. Sometimes it is a local owner with a lawyer’s advice, and the parcel stays.
The two lists, side by side
| For rent by owner | Absentee owner | |
|---|---|---|
| What it is | A vacancy, right now | A fact on the tax roll |
| Where it comes from | Rental portals, classifieds, marketplaces, yard signs | The assessor export, mailing address versus situs |
| Refresh | Daily. Aged ads first | Annually, with a quarterly check for sales and new absentees |
| The unit of the record | The owner, with properties attached | The owner, with parcels attached |
| The signal to work first | Ads older than thirty days, price reductions | Out-of-area mailing address, long hold, multiple parcels |
| The number quality | Usually the owner’s real cell, from the ad | A vendor match to the mailing address; treat as unverified |
| The right call | The two-question FRBO script, today | The annual plan call, or a circle call when something sells near their rental |
| Timeline to a listing | Twelve months, from the lease end date | Years, or at the next vacancy or repair |
Where the two lists meet
The best landlord lead in your market is on both lists: an out-of-area owner, on the absentee export, who has just posted a rental ad. You already had their name, their mailing address, their purchase year and their parcel count before the ad appeared, and now you have a phone number they published themselves and a vacancy they are living through. That call opens with everything the FRBO script asks for already answered, and it is the reason to build the absentee list first and then match FRBO ads against it as they arrive.
The match is by owner name and property address, not by phone, because the absentee list will not have a reliable phone and the ad will. When the ad’s address matches a parcel on the absentee list, the phone from the ad becomes the verified number on the owner’s record, which is the only free phone verification you will ever get on a landlord.
Compliance is the same on both
A rental ad is an invitation to tenants. An assessor record is a public document. Neither creates any relationship with you and neither is an exception to the do-not-call rules, which apply to both lists in full: registry scrub inside 31 days, internal list check, and the calling window set by where the owner actually is. For an absentee owner, that is the mailing address, which may be two time zones away from the property. A 9 a.m. call about a rental in Florida is a 6 a.m. call to an owner in Oregon.
Two public records deserve a note because guides sometimes suggest them: eviction filings and code enforcement actions. Both are public in most jurisdictions, and both mark an owner under stress. They are legitimate signals to prioritize an owner already on your absentee list. They are a poor list to build from, because an owner in the middle of an eviction is not in a position to hear a call about their long-term plan, and because the tenant’s situation is not your business. Use them to sort. Never to source.
The weekly routine
The absentee list gets built once, from the export, with the refinements above, and the owners get matched to phones and loaded as owner-level records with their parcels attached. It is re-pulled once a year and checked quarterly for sales, which remove parcels, and for new mismatches, which add them.
The FRBO sources get checked on two or three fixed mornings a week. New ads are matched against the absentee list first. Every new owner becomes a record with the lease-end anchor the FRBO script is built to capture. Aged ads and price cuts go to the front of that morning’s calls. Duplicates by phone number are collapsed into one owner before anyone dials.
Then both lists feed one calendar: the FRBO calls today, the sixty-day calls on their dates, and the absentee plan calls spread across the year, all in the priority lane rather than the rotation, because every one of them is a call the owner is expecting or a call with a specific reason behind it. The list-building piece covers merging these with your expired and FSBO files without losing the do-not-call flags. Landlords are a small list. Slow, too. Built as two lists and worked as one calendar, they are the most patient and least contested source of listings most agents never organize.
