If you inherited a house in New Mexico — whether it's in Las Cruces, somewhere else in Doña Ana County, or anywhere in the state — and you're trying to figure out how to sell it, this guide walks through the whole process. It covers what probate is, when you need it, when you don't, how long it takes, and how to sell without waiting for probate to fully close.

Nothing here is legal advice. Talk to a New Mexico probate attorney about your specific situation. But this should give you a real map of the terrain before you start.

The first question: is the estate in probate yet?

Before anything else, figure out whether probate has been opened. This determines everything else.

  • Probate is open. Somebody — you or another family member — filed with the New Mexico court system and a personal representative (executor or administrator) has been appointed. You should have Letters Testamentary (if there was a will) or Letters of Administration (if there wasn't). This person has authority to sign for the estate.
  • Probate hasn't been opened. The property is still technically titled in the deceased owner's name, and nobody has legal authority to sell it yet.
  • Probate was never opened and the death was years ago. More common than you'd think, especially with older Doña Ana County properties. There's a workaround for this — the Affidavit of Heirship — which we'll cover below.

New Mexico probate basics: three tracks

The New Mexico Uniform Probate Code (NMSA Chapter 45) provides three main paths, each with different timelines and requirements.

1. Informal probate (fastest, most common)

Informal probate is the default track for uncontested estates in New Mexico. If there's a valid will, no family disputes, and no complicated assets, this is what you use. Filed with the district court in the county where the deceased lived — for Las Cruces / Doña Ana County residents, that's the Third Judicial District Court.

How long it takes: Letters typically issue within 30-90 days from filing, sometimes faster if the paperwork is clean. From that point the personal representative can sign to sell property. The full probate stays open for at least 6 months (the statutory creditor claim period), but you don't have to wait for it to fully close to sell.

2. Formal probate

Formal probate is used when there's a contested will, disputes among heirs, no will and multiple potential heirs, an insolvent estate, or other complications. It requires a hearing before a judge and more extensive court supervision.

How long it takes: 6-18 months depending on complexity and whether hearings need to be scheduled. Can be longer if the estate is contested.

3. Small Estate Affidavit (NMSA 45-3-1201)

For estates where the personal property (excluding real estate) is worth less than $50,000, New Mexico allows heirs to bypass probate entirely using a Small Estate Affidavit. This is filed with anyone holding assets (banks, brokerages), not with the court. Real property (houses) generally cannot be transferred with a Small Estate Affidavit — but for the personal-property side of a small estate, this is a huge shortcut.

Practical note: if your inherited house is the main asset, the Small Estate Affidavit alone won't get the house sold. You'll typically still need informal probate for the real estate, or the Affidavit of Heirship path described next.

Affidavit of Heirship: the workaround for old, un-probated houses

Here's a situation we see often in Doña Ana County: an owner died 5, 10, 20 years ago. The house is still titled in their name. Nobody ever opened probate. The heirs (children, siblings, whoever) have effectively been treating the property as their own, sometimes paying taxes, sometimes not. Now someone wants to sell.

Opening a formal probate on a decades-old estate is possible but painful. New Mexico offers an alternative: the Affidavit of Heirship. This is a sworn statement, typically prepared by a title company or attorney, identifying the heirs and their relationships to the deceased. Once recorded with the Doña Ana County Clerk, it establishes chain of title without a formal probate proceeding.

Requirements are strict:

  • The death must have occurred a certain number of years ago (varies by title company practice, typically 2+ years)
  • The affidavit must be signed by disinterested parties (not the heirs) who knew the deceased and can identify the family
  • All heirs must be identified and (typically) sign a joint deed conveying the property
  • The title company evaluating the situation must be willing to insure the title based on the affidavit

Not every situation qualifies, but when it does, the Affidavit of Heirship path can shave 6-12 months off the timeline compared to opening probate. We've closed Doña Ana County sales this way regularly.

What the personal representative (executor) actually needs to do

If you're the named executor of a will — or a family member preparing to serve as administrator of an intestate estate — here's the practical checklist for selling the inherited house:

  1. File the will (if any) with the probate court in the county where the deceased lived. For Las Cruces / Doña Ana County residents, that's the Third Judicial District Court (though the Doña Ana County Probate Court also handles some informal filings).
  2. Apply for Letters Testamentary or Letters of Administration. This is the piece of paper that gives you legal authority to sign for the estate. Title companies and buyers (including us) need to see it before closing.
  3. Notify heirs and creditors as required by NM law. Publication in a newspaper of general circulation is typically required.
  4. Inventory the estate, including the real property, and file with the court.
  5. Get an EIN for the estate from the IRS (free, online). You'll need this to open an estate bank account and to file estate taxes.
  6. Pay outstanding debts — property taxes, HOA arrears, utility bills, funeral costs. Some of these can be paid from sale proceeds at closing.
  7. Sell the property. The personal representative signs the deed. Sale proceeds go into the estate account.
  8. Distribute proceeds to heirs according to the will (or NM intestacy rules under NMSA 45-2-101 through 45-2-115 if no will).

Community property complications

New Mexico is a community property state. If the deceased was married, half of the community property (including the house, if it was acquired during marriage) typically passes to the surviving spouse automatically — sometimes without probate at all. The other half passes through the deceased's estate.

Practical impact: if a Las Cruces house was owned by a married couple and one spouse died, the surviving spouse may already be able to sell the house without probate, using a Sworn Statement or a Community Property Affidavit. If you're the surviving spouse, ask a title company or attorney about this before assuming you need to open probate. It can save months.

Out-of-state heirs: how the remote sale works

A huge share of the inherited-house sales we work on involve heirs who live outside New Mexico. Doña Ana County has a lot of longtime residents whose adult children moved to Albuquerque, Denver, Phoenix, Chicago, or the East Coast decades ago. When a parent passes, the children inherit but don't want to fly back to sell the house.

Here's how the remote sale works:

  • Communication is by phone, email, and video. We don't need you to visit Las Cruces at any point.
  • Someone needs to walk the property. Either a family member, a neighbor with a key, a property manager, or (with your permission) us. We can also send you photos and video.
  • Closing documents are signed remotely. Once the offer is accepted and title clears, the title company overnights documents to a mobile notary in your state. You sign there. This is standard practice.
  • Funds wire to your account the next business day after recording. You never touch a physical check.

We do this routinely. It's not exotic.

Selling to a cash buyer vs. listing with an agent

You have two main options for selling the inherited house once probate is far enough along.

Traditional MLS listing: Best if the property is in good condition, you have 3-6 months, and you're comfortable managing repairs and showings from wherever you live. You'll typically net more than a cash offer, but you'll pay 5-6% agent commissions and 2-3% closing costs. If the property needs work, you'll either eat repair costs upfront or accept a lower price and repair credits after inspection.

Cash sale to an investor (like us): Best if the property needs work you don't want to manage remotely, if you want a fast close, or if you want to avoid the uncertainty of buyer financing falling through. Our offers are typically 8-15% below post-repair market value — the spread covers our repair budget and holding costs. But we pay all closing costs, close in 7-30 days, and take the property as-is, including whatever's inside.

Neither is universally the "right" choice. If your inherited Las Cruces house is a well-maintained East Mesa home from 2010, list it. If it's a 1960s adobe in the North Valley that hasn't been updated in 30 years and you're managing it from Ohio, a cash sale probably makes more sense. We'll tell you honestly which category your property falls into when you call.

What we do differently for inherited-house sales

We've closed a lot of these. A few things we handle that a general residential cash buyer might not:

  • Work directly with your probate attorney to time the closing around when Letters are expected to issue
  • Sign a purchase contract during probate, subject to the personal representative receiving Letters — so you can lock in the sale early
  • Coordinate with title companies experienced in Doña Ana County probate transfers and Affidavit of Heirship situations
  • Take the property with everything inside — you don't have to sort through decades of a parent's belongings
  • Handle out-of-state closings by mobile notary in your home state
  • Settle back taxes, HOA arrears, and recorded liens out of closing proceeds so you don't have to write checks upfront

A note on timing

The single most common mistake we see out-of-state heirs make is waiting too long to start the probate process. Every month a house sits vacant, it deteriorates. Copper wire gets stolen. Roofs leak. Squatters move in. Property taxes and insurance keep coming due. The estate keeps paying carrying costs.

You can't sell until probate is far enough along, but you can start probate immediately. If it's been more than a few months since the death and you haven't opened probate, that's usually the first call to make — to a NM probate attorney. Then, once Letters are close to issuing, call us.
