Humorist, author and radio star Garrison Keillor has placed his seven-bedroom Georgian-style mansion in St. Paul, Minn. on the market for $1,650,000.  The Keillor listing is not new news, but in catching up on items, we wanted to share with readers the complicated Keillor tale, which first broke in the St. Paul Pioneer Press last week, when that paper was first to report on Keillor's listing of the house, which is at 427 Portland Avenue in St. Paul's Crocus Hill neighborhood. Records show that Keillor paid $710,000 in 1988 to purchase the home, which measures either 5,168 square feet (according to public records) or 5,960 square feet (according to listing information).  However, one could argue that Keillor's housing-related news dates back even earlier, given that Keillor in January had sued a neighbor who had planned to build a two-car garage just seven feet from his home. The 'Prairie Home Companion' host ultimately reached a settlement with the neighbor. Built in 1915 and designed by Emmanuel Masqueray, Keillor's house on Portland Avenue has five baths, 13-foot ceilings (according to the New York Times in 2006, or 14-foot ceilings, according to listing information), and a circular staircase, and sits on a 0.2-acre parcel, according to public records and listing information. The New York Times wrote an excellent feature on the house in 2006. There's more to the story than just the settled dispute, however. Now, Keillor reportedly wants a house with an airy, first-floor studio where he can work, according to news accounts. As such, Keillor has been reported to have made an offer on a house nearby with 4,000 square feet more of space. The house that Keillor reportedly is trying to buy is the 9,134-square-foot George F. Lindsay house at 294 Summit Avenue in St. Paul, which appears to have been on the market recently for $2.15 million. The current owner of the Lindsay house is not a celebrity. We'll of course keep you posted as we learn more about Keillor's real estate transactions. The online listing sheet for his Portland Avenue mansion recently was taken down, suggesting that a deal may be in the works. And, we suspect we won't be the ones who break the story of him purchasing the Lindsay house if he does indeed end up buying it --we have a feeling the Twin Cities press will beat us to the punch. Keillor (pictured here with Lindsay Lohan) owns plenty of other real estate around the country, including a 1,681-square-foot house in Brooklyn Park, Minn., a co-op unit at 300 Central Park West in Manhattan, and two separate parcels -- measuring 5.87 acres and 5.66 acres -- in Pierce County, Wisc., according to public records. The 300 Central Park West unit, the New York Times reported in 2006, is one that Keillor is on his second tour of duty owning. He purchased it for $800,000 in 1987, sold it for $1.5 million in 1993, and purchased it again in 2006 for $3.5 million. 'I always sort of regretted selling,' Keillor told the Times in 2006. 'It's a chance to recoup one's regret.'
