“We are not commenting on Dr. Ueno’s and Dr. Kuno’s personal matters at this time,” a spokesman for their S &R Foundation told us Tuesday.

But it looks like the couple is trying to keep the one-of-a kind properties historically pure — inside and out.

“If anyone is going to buy Halcyon, they’ll be good stewards of this historic property,” said Robert Devaney, who first reported the pending contract in the Georgetowner. Devaney lives in one of Halcyon’s six longtime rental units separated from the main house, and was one of the tenants who, by law, had to be notified of the prospective sale — including buyers and price.

The property went under contract last week, but it’s not a done deal until the sale is finalized. The listing agent, Mark McFadden of Washington Fine Properties, declined to comment.
