According to Prudential's 2016 Retirement Preparedness Study, 54% of Americans nearing retirement age "have no idea" how much money they'll need for their post-career years. What's more, the same percentage of Americans nearing retirement only have $150,000 saved for their so-called "Golden Years" - nowhere near enough cash to live on for 20 or even 30 years of retirement.

That's where part-time income can help beef up retirement savings. But what are the best income-producing options in retirement? Here, from the mouths of experts are a "working" retiree's best bets.

With real estate prices and health care rising, and with interest rates on an upward spike as the U.S. economy gathers significant strength in 2017, retirees - and near-retirees - may wonder just how far their household dollar may stretch in retirement, especially here in the U.S.

One antidote is to do what 400,000 retirement-minded Americans are doing and find a comfortable, affordable landing spot overseas.

After all, Florida and Arizona aren't the only places on earth with plenty of warm sunshine, palm trees, good food and friendly people - they just happen to be among the most expensive retirement destinations.

Change that dynamic, passport in hand, by opting for one of the global locales to add some international luster to your golden years - straight from the mouths of ex-pats who live there.
