Jon was spotted checking out an apartment at Trump Place in New York City on Thursday, according to multiple media reports.
According to Gawker.com, which first reported the news, a realtor showed Jon at least one apartment in the multi-building high-rise apartment complex which is located on Manhattan's Upper West Side.
"Supposedly the apartment is a river-facing 1 bedroom that has been for rent, and rents at about $3200 a month," a building resident later told Gawker.
"[Jon] has been going back and forth to New York a lot," a source toldPeople in a Friday report.
Jon returned to the couple's home in Wernersville, PA on Friday, according to People. Although their eight children were home, Kate had already left the house early Friday morning, according to a People source.
Earlier this week, TLC has announced that Jon and Kate will be revealing some "life-changing decisions" concerning their relationship problems during a special one-hour broadcast their Jon & Kate Plus 8 reality show on Monday at 9PM ET/PT.
"Recently we've made some life-changing decisions. Decisions that will affect every member of our family. Ones that we hope will bring each of us some peace," Kate said during the voiceover of a 30-second version of new promotional commercials the network began running Wednesday night.
"Jon & Kate have an announcement." the network stated in on-screen text as Kate's voiceover and background music aired over video footage which showed Jon and Kate maintaining their distance during recent family activities.
"Monday, a one-hour Jon & Kate Plus 8 special. A family in turmoil. A relationship at a crossroads. Where do they go from here?" TLC stated in additional text that slowly flashed on-screen and faded throughout the 30-second commercial.
