When someone dies without a will, the family does not decide who owns the house. A statute does, and it was written long before anyone in this family was born.
That is the whole niche in one sentence. Everything difficult about buying an intestate property follows from the fact that the owners are determined by a formula rather than by intention, and that the formula often produces a list of owners nobody expected, including people the deceased had not spoken to in decades.
How the Statute Decides
Every state has an intestate succession scheme, and while the shapes rhyme, the details differ enough that you cannot carry a rule of thumb across a state line.
The common pattern runs spouse first, then descendants, then parents, then siblings, then progressively more distant relatives. Where it gets complicated is the middle. A surviving spouse may take everything, or may take a fraction with the rest going to children, and in several states that split changes depending on whether the children are also the spouse's children. Blended families produce outcomes that surprise everybody involved.
Two other quirks matter in practice. Descendants of a predeceased child usually step into their parent's share, which is how a house ends up with a grandchild owning a twelfth of it. And adopted children are generally treated as biological children while stepchildren generally are not, which produces some of the most emotionally difficult conversations in this business.
What all of this means for you is straightforward: until someone with authority has determined the heirs, you do not know who the sellers are. Not approximately, not probably. The family's own account of who owns it is a starting point, and it is wrong often enough that you should treat it as unverified.
Why This Is Not Just Probate
Intestate estates go through probate, so much of the general process applies and is worth reading alongside this, per probate real estate. Three differences change how the deal runs.
There is an administrator rather than an executor. Nobody was nominated, so the court appoints, usually following a statutory priority order. Family members can contest who gets appointed, and that fight alone can consume months before anything about the house is discussed.
A bond is more likely to be required. A will commonly waives it. Without one, the court will often require the administrator to post a bond sized to the estate, which costs money the estate may not have and which can delay an appointment while it is arranged.
And the authority to sell is narrower. Where a will grants a power of sale, an administrator may need specific court permission, and in some states the sale is confirmed in a hearing with a procedure that allows other parties to bid it up. That is not a formality, and not something to find out about after you have a contract.
The practical result is that intestate estates run slower and less predictably than testate ones. Price your patience accordingly, and build the timeline into your paperwork honestly rather than optimistically, per purchase agreement clauses for investors.
The Houses Nobody Ever Opened Probate On
This is the version of the niche worth actually hunting, and far more common than investors realize.
Someone died in 2009. The family did nothing, because there was no mortgage and no urgency and nobody wanted to pay a lawyer. A daughter has been paying the taxes and living in it. Title still shows the deceased. Fifteen years later, everyone assumes it is hers, and legally it is not, or at least not entirely.
The signals are visible in ordinary data: a deceased owner on title, taxes being paid by someone else, no recorded transfer since a date long past. Some of these surface through the same records you would pull for a normal probate search, and some only appear when you notice that the person on title would now be a hundred and four years old.
These properties are usually in poor condition, often occupied by a relative, and unsellable in their current state because no one can convey clean title. The occupant may have been trying to sell for years and been turned away by agents who could not solve it.
Which is precisely the opportunity. An investor who understands the clean-up, and is willing to fund it, is offering something no other buyer in the market is offering. It is also slow, and the fee for solving it should be priced into the deal rather than treated as goodwill.
Clearing It Up
There are several routes and which ones exist depends entirely on your state, which is why this is a conversation with a local attorney rather than a checklist.
Full administration is the reliable one. Someone petitions, gets appointed, the heirs are determined by the court, and the sale happens with clear authority. It is slower and it produces title everybody will insure.
Small estate procedures exist in most states and are far faster, but they are capped at a value threshold and the caps are often too low to include a house. Worth checking rather than assuming.
Some states offer a proceeding specifically to determine heirship, which resolves the ownership question without a full administration. Others recognize an affidavit of heirship, a sworn statement from disinterested witnesses about the family structure, recorded in the county records. Those are cheap and fast and title companies vary enormously in whether they will rely on one, particularly for a sale rather than a refinance. Ask your underwriter what they will accept before you build a strategy on it, per working with a title company.
And whether you are in a state where an attorney runs the closing or a title company does changes who you are coordinating with throughout, which is worth understanding early, per attorney states versus title states.
Getting Every Signature
Where the estate has not been administered and the heirs are conveying directly, you need all of them. Not most.
An heir who owns one-sixteenth can block the sale as effectively as one who owns a half, because a buyer taking title without their interest has not bought the whole property. Title insurance will catch it, and if it does not, you have created a problem for yourself that surfaces on resale.
So the work is genealogical before it is transactional. Build the family tree, confirm who has died and whether they left descendants, and locate people who may have moved several states away and have no idea they own part of a house. That is real skip tracing rather than a phone number lookup, and it sits at the harder end of skip tracing for real estate investors. Where the heirs are scattered across states, the coordination problem gets a fuller treatment in out-of-state heirs.
Expect one of them to be unreachable, uninterested, or opposed. That situation has its own mechanics and its own remedies, which is the subject of heirs in conflict.
Talking to the Family
You are contacting people about a parent who died, often about a decision they have avoided for years, and sometimes about a fact they do not know yet, which is that they own part of a house.
Lead with the property and let them tell you the situation. Do not open by explaining their own family's legal position to them, however well you understand it, because it is presumptuous and because you may have it wrong.
Be careful about who you tell what. Family members commonly have very different understandings of who owns what, and an investor who repeats one heir's version to another has walked into the middle of something. Say less, ask more.
And be genuinely willing to explain the process, because most of these families have been given no useful information by anyone. Being the person who explained clearly what an administration is, and then encouraged them to get their own attorney rather than steering them to yours, is worth more in this niche than any offer, and it follows the standard in talking to sellers in difficult circumstances.
What This Niche Rewards
Intestate property is a competence niche rather than a marketing niche. The lists are not secret and the houses are not hidden. What keeps competition out is that the deals require an investor to understand a process, wait through it, and fund a legal clean-up whose cost is uncertain at the outset.
That is a poor fit for a wholesaler working on assignment velocity and a good fit for an investor with cash, a relationship with a probate attorney, and enough other deal flow to be indifferent about a four-month calendar. The map of what else is worth working, and how these situations overlap, is in the guide to motivated seller niches.
What you are being paid for here is not finding the house. Anybody can find it, and in many cases the family has been trying to give it away for a decade. You are being paid for being the only buyer in the market who knows what to do next.
