Your post does not contain sufficient information to answer this question intelligently.
To clarify, you told us that the house sold for $250k, which any reasonable person would assume is the actual sale price (as opposed to the net amount received). However, you didn't say whether the property was subject to a mortgage. The mortgage balance would be deducted from the sale price, as would the cost of sale, which could be anywhere from 5-10% of the sale price. You didn't tell us about any other assets (other than the "mostly worn out furniture") or any other estate debt. If the house was subject to a $125k mortgage and there were costs of sale of 5% of $250k, that means the net amount received from the sale would be $112,500. The executor would be entitled to a fee based on the gross value of the estate, and there'd be at least the cost of the funeral and burial. Even of those things totaled $12,500 (which would be fairly low), then there'd be $100,000 to distribute to you and 3 other heirs, which means each of you would get $25k.
Obviously, the numbers could be quite different (e.g., maybe there was no mortgage), but it's not hard to imagine that $25k would be an appropriate amount. Of course, this should all be detailed in probate court filings, which should have been served on you, and you likely were entitled to request and receive an accounting from the executor.
Probably. However, if your intent was to ask whether the $25k inheritance you received is taxable income, the answer is that it probably isn't.
