Taylor Swift to Conor Kennedy: We Might Be Over ... I'm Still Buying that House!

Taylor Swift hasn't pulled the plug on her deal to buy a mansion next to the Kennedy compound in Massachusetts ... yet ... despite rumors she split from her Kennedy family boyfriend -- TMZ has learned.

A source connected with the real estate transaction tells us, the deal for the $4.5 million Hyannis Port home is still going full steam ahead ... and is currently scheduled to close in two weeks.

As we reported, Taylor plunked down the cash for the home -- located across the street from Ethel Kennedy -- in order to be closer to her 18-year-old boyfriend Conor Kennedy.

Reports are now circulating the couple has called it quits -- but so far, that hasn't changed Taylor's real estate plans.

Still counts as an investment, right?
