Yahoo.com | When every part of a presidential candidate’s life goes under the microscope, it’s not surprising that some of their homes have led to controversy. In fact, for one candidate, two properties have become the center of a heated debate.

One hopeful’s Federal-style house was formerly the headquarters for a culinary reality series. One candidate owned a collection of mansions, while another created a website to sell his comparatively humble house. The GOP hopefuls' home values range from $325,000 up to $12 million, and range in size from around 3,000 square feet to 9,500 square feet.

Read on to learn about these abodes, located in nine states, and find out who owns, has owned, or rents each house.

Texas Gov. Rick Perry’s choice of living quarters while the Governor’s Mansion (pictured) undergoes repairs has proven controversial. An Associated Press article reported in May 2010 that at that time, because of Perry’s house rental at the Estates of Barton Creek in Austin, “taxpayers have spent at least $592,000 for rent, utilities, repairs, furnishings and supplies.” The house Perry rents was on the market in 2007 for $1.85 million, according to the article.

Barton Estates is not Perry’s only real-estate-related source of bad publicity. Rick Perry and his father have leased a hunting ranch with an offensive name, located in Throckmorton, Texas, for decades. Witnesses differ with Perry as to when a rock bearing this name was obscured.

Herman Cain

Location: McDonough, GA
Cost: $425,000 in 1998
Bedrooms: 3
Bathrooms: 4.5
Square Footage: 3,203

Herman Cain’s house was built in 1997 and the Cains purchased it in 1998, making them the sole owners of this 14-year-old house. But they might not want to sell it just yet, as Zillow estimates the property’s current worth to be $290,700.

Mitt Romney

Location: Park City, UT
Cost: $5.25 million
Bedrooms: 7
Bathrooms: 9.5
Square Footage: 9,500

Mitt Romney wins the award for the Republican presidential candidate with the most real estate. In 2009, he had four mansions. His post-and-beam-log lodge (pictured here) was listed that year for $5.35 million (then removed), but real-estate website Zillow.com estimates the value around $2.6 million.

That year, he also sold his Boston-area 1930 house for $3.5 million. Rounding out the collection are a $12 million beachfront compound in La Jolla, Calif., and a lake house in Wolfeboro, N.H.

Ron Paul

Location: Lake Jackson, TX
Cost: $325,000
Bedrooms: 4
Bathrooms: 5
Square Footage: 5,500

Ron Paul announced in April on his Facebook page that he’s selling the house where he and his family (including his son, U.S. Sen. Rand Paul) have lived for more than four decades. He created an official website for the house, “ Buy Ron Paul’s House ,” which says “generations of Liberty [ sic ] loving kids have grown up here, and you can continue the tradition.”

Although there are numerous photos of the pool and patio area on the site, it did not seem to occur to the three-time presidential candidate to include any photos of the front of the house or the interior.

Michele Bachmann

Location: Stillwater, MN
Cost: $760,000 in 2008
Bedrooms: 4
Bathrooms: 4
Square Footage: 5,200

In 2008, Michele Bachmann and her husband Marcus moved from the 3,056 square-foot Stillwater home where they’d lived for 16 years to a larger one (pictured here). The new house, also in Stillwater, is located overlooking the 18th hole on the StoneRidge Golf Course. It was priced at $1.75 million when it appeared in the 2007 Parade of Homes, then assessed at $1.271 million in 2008, but the Bachmanns nabbed it for $760,000.

At the time the house was featured in the Parade of Homes as a “dream home,” the Minnesota Independent selected some highlights of the property quoted from the description:

"The arched stone entry is complimented with a western red cedar distressed door with iron highlights. Once inside the foyer, iron rails and hand scraped walnut plank flooring invites you into the gallery where arched openings lead to the magnificent main floor spaces. Both the formal dining adjacent to the foyer and a quaint breakfast bay overlook the golf course allowing for quality entertaining or a casual living atmosphere."

The same article lists other features of the home, including a maple kitchen with granite and limestone countertops, a wine cellar, and a paneled library with see-through fireplace.

Jon Huntsman, Jr.

Location: Washington, DC
Cost: $3.6 million
Bedrooms: 5
Bathrooms: 4.5
Square Footage: 5,500

Before Ambassador Jon Huntsman, Jr., purchased this 1911 brick Federal-style home in historic Kalorama last year, it housed the seventh season cast of the TV show “Top Chef.” Viewers will recognize the wraparound patio terrace as the site where contestants faced elimination from the show.

Newt Gingrich

Location: McLean, VA
Cost: $995,000 in 2000
Bedrooms: 5
Bathrooms: 4.5
Square Footage: 5,206

Newt Gingrich’s house on a cul de sac in McLean, Va., was built in 1987. The real-estate website Zillow.com now estimates the home’s value at nearly $1.275 million.

Rick Santorum

Location: Leesburg, VA
Cost: $850,000 in 2007
Bedrooms: N/A
Bathrooms: 3.5
Square Footage: 5,040

In addition to his more modest house in Penn Hills, Pa., Rick Santorum also lived in this two-story residence on 3.76 acres in Leesburg, Va., until 2007. It was purchased new in 2001 for $643,361. The question of Santorum’s residency location was the catalyst for a frothy controversy spanning more than a decade, as detailed here.
