CORRECTION: An earlier version of this item misidentified the designer and owner of an Annapolis estate for sale. Paul Johannes designed the home, not Johannes Greco. The home’s owner was John Greco, who was a builder not an architect. 

The late Paul Johannes designed houses in the Downs on the Severn River in Annapolis that honor the natural beauty of their surroundings with materials such as stone and wood and floor-to-ceiling windows to frame views of the river.

Now the 7,783-square-foot home Johannes designed for the late builder John Greco in 1984 is being listed in an estate sale. The $4.3 million property– with water views from every room — is among the most expensive properties on the market, according to Rockville-based multiple-listing service MRIS.

The house at 1487 Tenbury Common in Annapolis, which was renovated within the past three years, has an open floor plan with a vaulted, beamed ceiling. Skylights, glass doors and windows flood the home with natural light. The home sits on more than two acres, which include a dock with four boat slips and a swimming pool.

Real estate agent Lori Woods-Fortney of 111 Magnum Properties says that the interior of the house was decorated with Colorado and the West in mind. The home has four bedrooms and five full bathrooms. It also has an in-law suite, four fireplaces and a three-car garage.

The master suite has a fireplace in the sitting area with a panoramic view of the river and a luxury marble bathroom with a soaking tub set under a skylight and in front of wide windows with water views. A video of the property can be viewed here. For more information visit www.LoriWoods.ismyREagent.com or call Woods-Fortney at (410) 808-1469.

Rental rates have yet to be determined. Leasing is anticipated to begin in the spring of 2014. For more information, call (888) 639-4175 or visit the Swift’s Web site.

Many D.C.-area homeowners still underwater

The hot housing market in 2013 in the D.C. area has resulted in significantly higher home values for many residents.

But negative equity — which occurs when homeowners owe more on their mortgage than the value of their property — is slowly declining overall but lingering in many areas.

In the third quarter of 2013, 22.3 percent of borrowers in the D.C. area were underwater, down from 28.5 percent during that same period a year before, according to Zillow‘s latest negative equity report.

The communities with the highest proportion of underwater homeowners are Prince George’s County with 47 percent and Charles County with 45.8 percent.

Falls Church City fares the best at the moment, with just 7.0 percent of homeowners with a mortgage underwater. In the District, 14.2 percent are underwater, and in Montgomery County, 16.4 percent of homeowners with a mortgage have negative equity.

Zillow’s data shows that negative equity in the D.C. region peaked in the second quarter of 2011 when 33.0 percent of all homeowners with a mortgage were underwater.

New air scrubbing device makes fans of asthma sufferers 

If you or someone in your family struggles with allergies or asthma, you may want to think about turning on a fan in your home this winter. The new “Fan Buddie” filter is designed to turn a regular box fan into an air scrubber so you can breathe easier even in winter.

The Fan Buddie filter, which is made with PollenTEC screens and an extra layer of anti-microbial filtration, every couple of hours scrubs up to 1,500 feet of cubic air — that’s equivalent to cleaning all the air in a 15- by 15-foot room several times a day. The filter is designed to capture a wide array of airborne materials, including pollen, pet dander, mold spores and dust mites.

The $29.95 Fan Buddie works by peeling off the Velcro adhesive backing and sticking the device onto the frame of a box fan.

For consumers without a box fan, the company also offers a Fan Buddie already installed on a box fan for $55. The filter can be peeled off and washed in the dishwasher. The Fan Buddie is available online at www.fanbuddie.com.
