It's Joe Biden's favorite place – his summer home in Delaware where he has decamped dozens of times during his 1,000 days as Commander-in-Chief.

As DailyMail.com revealed on Tuesday he has spent at least 300 of those days either in the country's second smallest state or on vacation.

He bought the home at a time that it appeared his political career was over – five months after his Vice-Presidency had ended he was well into his 70s and after all he had decided to forgo a 2016 run for the top job.

But now that house in the tiny town of Rehoboth Beach could turn out to be a major embarrassment as Republicans continue their push to find business links between the 46th president and his son Hunter.

DailyMail.com has discovered that then-private-citizen Biden, who had spent virtually all his adult life in public service, bought the home for slightly under $2.75million – in cash.
