Dear Liz: My wife and I are both 66 and in good health. Currently we have about $1.2 million in IRAs. We’re receiving about $80,000 a year from a pension and $110,000 in salary. We have been aggressive about reducing any lingering debt. So we think we are in good shape for me to retire within the next year or so. If we decide to stay in our home rather than move, we will need to make some significant repairs and improvements. We were thinking of taking out a $200,000 mortgage to pay off our last remaining debt ($50,000 on a home equity line of credit) and fund the renovations. This would give us a better tax deduction and not incur the high taxes we would pay by making an IRA withdrawal. Our grown children have expressed no interest in the home after we die, so it probably would be put up for sale at that time. Does this seem like a reasonable approach if we choose to go that route? Anything we haven’t considered?

Answer: Considering the tax implications of financial moves is smart, but you shouldn’t make decisions solely on that basis. You especially shouldn’t take on mortgage debt just for the tax deduction. The tax benefit is limited to your bracket, so for every dollar in mortgage interest you pay you would get at best a federal tax benefit worth 39.6 cents. State income tax deductions might boost that amount, but you’d still be paying out more than you get back in tax benefits. You also would be locking yourself into debt payments at a time in life when most people prefer the flexibility of being debt-free.

If you’re comfortable having a mortgage in retirement, though, you might want to consider a reverse mortgage. Although once considered expensive loans of last resort for people who were running out of money in retirement, changes in the federal reverse mortgage program caused financial planners to reassess the no-payment loans as a potential wealth management tool. The idea is that homeowners could tap the reverse mortgage for funds, especially in bad markets, instead of depleting their retirement accounts.
Reverse mortgages are complex, though. The upfront and ongoing costs can be significant. Because you don’t make payments on the money you borrow, your debt grows over time and reduces the amount your heirs might get once the home is sold. You’d be smart to find a savvy, fee-only financial advisor to assess your situation and walk you through your options.
