Nine thousand two hundred twenty-seven acres, including Mount Vernon and a tract on Four Mile Run, he specifically bequeathed to individuals, as he did some of the lots.

The remaining lots and fifty thousand nine hundred seventy-five acres (some of which land was already conditionally sold) he directed to be disposed of, together with his live stock, government bonds and shares held by him in the Potomac Company, the Dismal Swamp Company, the James River Company and the banks of Columbia and Alexandria--the whole value of which he conservatively estimated at five hundred and thirty thousand dollars.

The value of the property he specifically bequeathed, with his slaves, which he directed should be freed, can only be guessed at, but can hardly have been short of two hundred and twenty thousand dollars more.

In other words, he died possessed of property worth three-quarters of a million and was the richest man in America.
Not all of the land that he listed in his will proved of benefit to his heirs.

The title to three thousand fifty-one acres lying on the Little Miami River in what is now Ohio and valued by him at fifteen thousand two hundred fifty-five dollars proved defective.
