A lot of Americans have seen their retirement  plans interrupted in the bad economy. According to CNN,  nearly half of the taxpayers in this country worry they will not have  enough money to retire comfortably. This is up from 29% in 2007, a report  from the Employee Benefit Research Institute found.
 
But the truth is, you can still get to  your destination. "Not everyone is going to be able to retire exactly  the way they want," says Denver financial planner Mark Brown. "But  I talk to people all the time who overestimate the scope of their problem  and underestimate their ability to do something about it."
 
Here are a few strategies for navigating  five of the most common retirement roadblocks.
Roadblock #1: You're carrying a big mortgage
 
The problem: It used to be that Americans  aimed to cross into retirement free of debt. But if you're in your fifties  or sixties, chances are you aren't planning a mortgage-burning party  anytime soon. The Joint Center for Housing Studies at Harvard says that  63% of homeowners ages 55 to 64 have mortgage or home-equity debt, up  from 49% in 1989. In addition, a third of retirees carry credit card  balances, reports the Federal Reserve. Such liabilities can be a dead  weight in retirement -- you'll have to make the payments even if your  expenses soar or your portfolio plummets.
Solution #1: Erase the debt if you can.  Assuming you have cash savings in excess of the balances (besides emergency  funds, that is), it usually makes sense to pay debts off around the  time you retire. But zero out HELOCs and credit cards first. "You  don't want a variable rate going into retirement," says Scottsdale  financial planner Jacob Gold.

As for your mortgage, if you're two-thirds  through the term, you're not benefiting much, if at all, from the interest  write-off. And after taxes you're unlikely to earn more in risk-free  investments than the cost of the debt, a recent Center for Retirement  Research study found. That said, if you'd have to pull from tax-sheltered  accounts to pay off the balance, you may want to consult a financial  planner about whether doing so would be worth the tax bite.
