Asking $300K in Denver, Colo., this two-bedroom, $1,270-square-foot loft includes much by way of "schoolhouse character," according to the brokerbabble. What exactly is "schoolhouse character"? Apparently original maple hardwood floors, tons of exposed brick, and large, square-paned windows.

This two-story Colonial house in Historic Bath, N.C., was built as the local schoolhouse in 1915. Now, for $129,000, buyers get a sunny little property with three bedrooms, hardwood cedar floors, and a six-month boat slip at the nearby Bath Harbor Marina. Check it out.

For $120K in Morrow, Ohio, one can have this totally cute two-bedroom, which boasts 1,236-square-feet and some "nice shade trees."

St. Louis' Lindenwood Schoolhouse, built at the turn of the century, now boasts 20 gleamy apartments and condos, including a one-bedroom, 1,044-square-foot unit currently asking $999 a month. The internal architecture of the units isn't all that historical looking (though the hallways have got a decidedly high school ambience), but the developer has done the work of installing schoolhouse-like details (like rehabbed backpack hooks and closets paneled in olde-style chalkboards) to up each apartment's quirk factor.

Originally built in 1893 as Cincinnati's Walnut Hills High School, this Romanesque Revival-style building, with its brick-and-stone edifice and turrets, now houses 23 residential units, one of which asks $139K.

West Harlem's P.S. 157 was converted into apartments 20 years ago, and since then the units, complete with the 10-foot-tall, 80-pound windows and restored copper cornice, have upped their rental price (roughly) five-fold. Back then, tenants were willing to shell out the $500 a month to live in a smidge of real estate that had just shouldered its way—via its "transitional and vernacular reworking of Chateauesque motifs"—into the National Registry of Historic Places. The current one-bedroom on the market asks $2,300. More about this conversion, right this way.

Like other loft conversions in this country, the units at Buffalo, N.Y.'s Oak School Lofts comes with the original chalkboards (painfully "painted over to blend with the rest of the decor") and other schoolhouse minutiae: original maple floors, original glass-doored bookshelves, and ceiling-to-floor windows. One-bedrooms start at $850.

Though it's a bit unclear just how much of the original Blue Hill Quaker School remains, this 6,873-square-foot estate in Media, Pa., does not demure from touting its historic roots.The foundations date back to 1873, and the surrounding acreage was considered "a geological and archaeological site" as early as the 20th-century, when the U.S. Geological Survey discovered the earth was rich in blue quartz and serpentine rock. The ask? $1.249M.

A two-bedroom in this circa-1887 brick school in Washington, D.C. is on the market for $575K.

The brokerbabble for this Oregon property, until recently known as the Bridge School and Academy, encourages interested parties to "bring your ideas!" That's probably because the 30,000-square-foot school is as of yet unconverted. Still, think of all the fun you can have with a cafeteria, industrial kitchen, library, and, of course, the gym with 20-foot ceilings. It's all up for $279,900.

Over in Washington, D.C., the circa-1890 Phillips School was converted into condos in 2002. Here a 1,075-square-foot two-bedroom asks $959K and comes with "dramatic 16-foot ceilings, awash with natural light."

Before it moved to Watertown, Conn., the northeast's prestigious Taft School was housed in this 4,625-square-foot historic abode in Pelham, N.Y. For $1.45M score six bedrooms, a 3/4-acre yard, and an entirely renovated interior.

Over in D.C. (what turns out to be a veritable hotspot of converted schoolhouses) this 1,503-square-foot condo at the old Edmonds School, which has undergone its conversion work just in the past year, wants $889,900 for its "luminous" space with 13-foot ceilings, 7-inch-wide plank floors, and exposed brick.

This rather adorable conversion comes with a huge lofty living room and open kitchen, plus three bedrooms and geothermal heating. It asks $224,900.
