Out Of Country Owners...?

One of my mentors (who I lost contact with) once told me to avoid buying properties at tax deed auctions with owners that live out of the country. I was wondering if anyone knows WHY he said that??

I am in Florida and a lot of properties near Orlando are owned by people in other countries, I assume because they want a vacation home near Disney. So I am very curious as to why he said that?

Any advice is appreciated because a property I am eyeing is owned by a guy in England.
