Selling without going back to court
A capped commission, not an automatic one
The personal representative is entitled only to "reasonable compensation," with the Orphans' Court setting the actual figure up to a statutory ceiling: 9% of the first $20,000, plus 3.6% of everything above that (§7-601(b)(2)). A will provision for a larger fee controls instead, unless renounced. The required attorney's fee is separate, judged by its own "fair and reasonable" standard, with the court capping the combined total.
The broker's commission doesn't eat into that cap
If the personal representative hires a licensed real estate broker to sell the house, that commission is its own administration expense — it isn't deducted from, or counted against, the personal representative's own statutory commission.
No separate capital gains rate — and a county layer too
Maryland taxes any gain as ordinary income at its graduated state brackets, plus the mandatory county piggyback tax every Maryland county levies. See Capital Gains Tax on the Sale for the full breakdown, including nonresident withholding.
Maryland's 23 counties plus Baltimore City
The Register of Wills in the decedent's home county handles the estate — Montgomery County, Baltimore County, Prince George's County, and Baltimore City (an independent city, separate from Baltimore County) among them. The statutory framework applies identically statewide; the county's own piggyback tax rate is what actually varies.
