In a Sale
What This Means When the House Is Being Sold
This is the number the whole tax conversation turns on, and it is frequently misunderstood by one degree. Families often know that inherited property gets a basis adjustment, but assume it happens automatically and needs no documentation. It does not work that way at tax time. The new basis has to be established and supported, usually by a date of death appraisal, and the burden sits on the taxpayer to show it.
Where a property was improved after the date of death, a new roof, a remodel, those costs generally add to basis and reduce the taxable gain, but only if documented. A family that pays a contractor in cash with no invoice has spent money that will not help them later.
Selling close to the date of death, with a supporting valuation already in hand, is the cleanest version of this.

What Tells Them Apart
Step-Up in Basis is the mechanism that resets cost basis for inherited property. Cost basis is the resulting number itself, the figure gain is measured against. Date of Death Value is what that number represents, and Appraisal is the report that typically establishes it in a form a tax return can rely on.
Questions
Questions People Ask
What is the cost basis of an inherited house?
Usually the property's fair market value as of the date of death, not what the original owner paid for it. That value is typically established with a retrospective appraisal. A tax advisor can confirm how it applies to a specific estate and what documentation supports it.
Do home improvements add to the basis of an inherited house?
Often yes, when they are capital improvements rather than routine maintenance, and when they are documented. A new roof generally adds to basis, a repaired faucet generally does not. Keeping invoices from any work done after the date of death makes the distinction easy to support later.
Do I need an appraisal to establish cost basis?
It is the most reliable way to support the number if the sale or a tax return is ever questioned. Some families rely on other valuations, but a retrospective appraisal ordered close to the date of death is generally the strongest documentation. A tax advisor can weigh the options for a specific estate.
