# Selling an Inherited House in Idaho: Probate, Community Property, and Your Options

Idaho informal probate, community property and survivorship deeds, the federal step-up in basis, and how to sell an inherited Idaho home as-is.

Inheriting a house in Idaho doesn't automatically mean a court case, and when it does, Idaho's informal probate is one of the lighter court processes in the country. Two things make Idaho different from most states sellers read about online: Idaho is a **community-property state**, which changes who inherits and what they owe in taxes, and Idaho's small-estate affidavit **cannot transfer real property** no matter how modest the estate is.

This guide covers when probate is required, how informal probate works, who inherits under Idaho's community-property rules, the federal step-up in basis, and how to [sell the house](https://intymproperties.com/we-buy-houses/), including as-is, once you have authority.

## Does Every Inherited Idaho House Go Through Probate?

No. An Idaho house passes outside probate when title was set up to transfer automatically:

- **Community property with right of survivorship.** Under **[Idaho Code § 15-6-401](https://legislature.idaho.gov/statutesrules/idstat/)**, spouses can hold real property this way, and at the first spouse's death the property transfers to the survivor by operation of law. The deed must expressly declare the survivorship estate: a deed that just names both spouses isn't enough.
- **Joint tenancy with right of survivorship.** The surviving joint owner takes the whole property automatically.
- **A revocable living trust.** Property titled in the trust passes to the successor trustee without probate.

If the house was in the decedent's name alone, no survivorship deed, no trust, some form of probate is required to move the title, and that's most inherited houses.

## How Does Idaho Informal Probate Work?

Idaho adopted the Uniform Probate Code ([Idaho Code Title 15](https://legislature.idaho.gov/statutesrules/idstat/)), and most estates use **informal probate** ([Title 15, Chapter 3](https://legislature.idaho.gov/statutesrules/idstat/)). The named executor or an heir files an application with the district court in the county where the decedent lived: in Boise, that's the Ada County courthouse. A court registrar reviews the application and appoints a **personal representative** without a hearing, unless someone objects or the paperwork is defective.

Once appointed, the personal representative receives **Letters** that give them legal authority to act for the estate, including listing and selling real property. In informal probate, the personal representative generally does not need a separate court order to sell the house.

The timeline drivers:

- **Creditor notice:** the personal representative may publish notice to creditors, who then have **four months** from first publication to present claims (**[Idaho Code § 15-3-801](https://legislature.idaho.gov/statutesrules/idstat/)**).
- **Closing the estate:** a personal representative can close the estate by sworn statement no earlier than **six months** after appointment (**[Idaho Code § 15-3-1003](https://legislature.idaho.gov/statutesrules/idstat/)**).

Realistically, an uncomplicated informal probate runs **six to nine months** start to finish. Contested estates, missing wills, or creditor disputes go through formal probate instead, which adds hearings and time.

## Does the Small-Estate Affidavit Work for a House?

No, and this is the most common misconception in Idaho estate matters. **[Idaho Code § 15-3-1201](https://legislature.idaho.gov/statutesrules/idstat/)** allows a successor to collect a decedent's personal property by affidavit when the entire probate estate is worth **$100,000 or less**, net of liens. It works well for bank accounts, vehicles, and personal belongings.

It does **not** transfer real property. The standard Idaho affidavit form says so explicitly. If the estate's only significant asset is a house, worth anything, the heirs need probate or a survivorship mechanism to get insurable title.

## How Does Community Property Change Who Inherits?

Idaho is one of nine community-property states, which is a fundamental difference from Florida's common-law system.

**If the house was community property**, acquired during the marriage, each spouse owned half. What happens to the decedent's half depends on the paperwork:

- Held as **community property with right of survivorship**: it passes to the surviving spouse outside probate ([§ 15-6-401](https://legislature.idaho.gov/statutesrules/idstat/)).
- Held as plain community property with no survivorship language: the decedent's half goes through probate, and under intestacy (**[Idaho Code § 15-2-102](https://legislature.idaho.gov/statutesrules/idstat/)**) it passes to the surviving spouse, but probate is still required to clear the title.
- If the decedent had a will leaving their half to someone else, children, for example, the will controls.

**If the house was separate property**, owned before marriage, or received by gift or inheritance, the surviving spouse's intestate share depends on the family: the spouse takes everything only if there are no surviving children and no surviving parents; otherwise the spouse takes half and the rest goes to the decedent's issue or parents ([§ 15-2-102](https://legislature.idaho.gov/statutesrules/idstat/)).

For surviving spouses, the single most valuable thing to check is whether the deed says "community property with right of survivorship." One phrase decides whether there's a probate at all.

## What Is the Step-Up in Basis?

Under federal tax law, [Internal Revenue Code § 1014](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title26-section1014&num=0&edition=prelim), inherited property gets a **stepped-up basis**: the heir's cost basis resets to the property's fair market value at the date of death, not what the decedent originally paid. Sell the house shortly after inheriting it for roughly its appraised value, and there's little or no capital gains tax.

Idaho's community-property status adds a significant benefit: under [§ 1014(b)(6)](https://uscode.house.gov/view.xhtml?req=granuleid:USC-prelim-title26-section1014&num=0&edition=prelim), **both halves** of community property get the step-up when the first spouse dies, the survivor's half included. In a common-law state like Florida, only the decedent's half steps up. For a surviving spouse who sells an appreciated Idaho home, that can mean the difference between a large capital gains bill and none at all. Confirm the specifics with a CPA; this is federal tax law, and the details of your situation matter.

## How Long Before You Can Sell?

- **Survivorship deed:** as soon as the death certificate and a survivorship affidavit are recorded, often within weeks.
- **Informal probate:** once the personal representative has Letters, the house can be listed and sold. You don't have to wait for the estate to close: selling the house is part of administering the estate. Sale proceeds flow into the estate, debts get paid, and the remainder is distributed to heirs.
- **Formal probate:** sales may require court approval depending on the posture of the case, which adds time.

The practical bottleneck is usually getting the personal representative appointed, weeks, not months, not the sale itself.

## Can You Sell an Inherited House As-Is?

Yes, and it's the norm rather than the exception. Most inherited homes come with deferred maintenance, dated interiors, or, in Idaho, freeze damage from winters the house sat vacant. A cash buyer purchases the property as it sits, works with the personal representative and the title company on the probate paperwork, and closes once authority is in place. That's the standard process on the InTym Properties [sell an inherited house](https://intymproperties.com/sell-inherited-house/) page. Inherited homes also accumulate title defects, unrecorded deeds and missing-heir interests especially, and the [title problems post](https://intymproperties.com/blog/sell-house-with-title-problems/) covers what clearing those involves. One more payoff wrinkle: if the decedent's house carried a reverse mortgage, the borrower's death is a maturity event and the loan is already due, with the servicer's deadline running on its own clock. The [reverse mortgage post](https://intymproperties.com/blog/sell-house-with-reverse-mortgage/) covers the heir options.

This is especially common for out-of-state heirs: one walkthrough coordinated locally, a written offer, and a remote closing: no trips back to Boise to manage contractors or showings. The post on [selling an inherited house from out of state](https://intymproperties.com/blog/sell-inherited-house-from-out-of-state/) covers the whole remote playbook, from securing the property to signing by mail-away or remote notarization.

## The Bottom Line

Selling an inherited house in Idaho is mostly a question of which lane you're in: survivorship deed (weeks, no probate), informal probate (six to nine months, but the house can sell early in that window), or formal probate (longer, court-supervised). Community property rules decide who inherits; the step-up in basis usually erases the capital gains; and the small-estate affidavit, useful as it is, won't move a deed. If you're not sure which lane applies, a title company or probate attorney can tell you from the deed and the death certificate, and a written cash offer costs nothing to get while you find out.

## Frequently asked questions

### Does an inherited house have to go through probate in Idaho?

Not always. In Idaho, a house passes outside probate when it is held as community property with right of survivorship, as joint tenancy with right of survivorship, or inside a revocable living trust. If the house was in the decedent's name alone, some form of probate is required to move the title, and that is most inherited Idaho houses.

### How long does Idaho probate take for an inherited house?

Most Idaho estates use informal probate under the Uniform Probate Code, where a court registrar appoints the personal representative without a hearing. An uncomplicated informal probate runs about six to nine months start to finish, but the house can be listed and sold as soon as the personal representative has Letters.

### Can you use Idaho's small-estate affidavit to transfer a house?

No. Idaho Code § 15-3-1201 lets a successor collect personal property by affidavit when the entire probate estate is worth $100,000 or less, but it does not transfer real property, and the standard Idaho affidavit form says so explicitly. If the estate's main asset is a house, the heirs need probate or a survivorship deed.

### Do you pay capital gains tax when you sell an inherited Idaho house?

Usually little or none if you sell near the date-of-death value. Federal law, Internal Revenue Code § 1014, resets the heir's basis to fair market value at death, and because Idaho is a community-property state, both halves of community property get the step-up when the first spouse dies, including the survivor's half.
