8 Things Financial Advisors Wish You Realized About Retirement

When it comes to planning for retirements, financial advisors have seen clients with good habits, and clients with bad tendencies. Kate Ashford presents a roundup of feedback from financial planners on what many people theyve encountered dont often realize about retirement. Kevin weighs in, framing retirement from a longevity angle:

“Many retirees simply don't want to consider what extended old age may mean in term of lifestyle and expense. Today, in the absence of other client information that might influence our projections, our long-range planning assumes living to 95 or beyond. Better health habits and continued advances in medical science all play a part in this thinking. Early planning to consider future care needs and living circumstances is essential. The need for assistance and or care will arise.”

Should You Lend Your Child Money to Buy a Home?

Kevin weighs in with considerations for parents lending adult children money to buy a home. He especially recommends formalizing the agreement with a promissory note and mortgage:

“The parents are going to have to work with a title company to create the required deed of trust documents and record these with the county in which the residence is located,” says Kevin Gahagan, a certified financial planner and principal of Mosaic Financial Partners in San Francisco. “This will secure their interest in the property.”

“A promissory note and mortgage should be executed between the parents and child,” he says. “Without this, the parents’ financial interest in the property could be jeopardized were the child to lose the house to creditors. It also provides evidence that the funds provided are a loan and not a gift.”

This formal loan document should state the loan’s interest rate, term and transfer-ability, Gahagan says. It should also include an amortization table showing the balance remaining and equity accrued at any point in the loan’s lifespan.

How Much of Your 401(k) Retirement Plan is Affected by Market Volatility?

Diversifying your portfolio combats volatitily, and is a strongly-recommended best practice for investors looking to take action against rocky market conditions. Another? Don’t lose your long-term vision:

In most cases, U.S. stock funds will see the greatest declines, more so than international stock funds, said Kevin Gahagan, a financial adviser at Mosaic Financial Partners in San Francisco. Fixed income bonds are not safe from a decline either, given the potential for rising interest rates. Still, if accounts are well diversified, employees won’t see a decline nearly as bad as the market as a whole, he said.

“The key for retirement plan participants is to not lose their long-term discipline and react to current market conditions,” he said.

Local 401(k) startups aim to bring retirement benefits to startups, small business [Subscriber Wall]

When it comes to small business and startups offering retirement benefits to their workers, is the 401(k) broker-provider the next target rife for startup disruption? Regardless, Kevin notes the need for checks and balances:

“Employers at a smaller firm may not have an HR department or a legal department and they’re going to need to work with what’s referred to as a third-party administrator, this is the firm that will keep you on the straight and narrow,” said Kevin Gahagan, a principal at financial advisory [firm] Mosaic Financial Partners.

Advisors weigh in on the Wall St. Journal's Critique of Morningstar Ratings

Kevin is quoted in Deborah Nason’s latest piece for CNBC's Smart Investing section, on the rating system employed by Morningstar. Kevin points out that low expenses is the true bottom line:

"The only metric that has been shown to have some degree of predictive ability is low fund expense," he said. "There is a reasonably consistent result that within any asset class or fund category, those funds with the lowest expenses will tend to outperform over time.

"This is one of the primary reasons that low-cost index funds tend to achieve top-quartile performance over time."

Should You Increase Your Homeowners Insurance If Your Property Value Spikes?

The median price for an American home has increased. If you own a home in a booming real estate market, how does this impact whether or not your insurance coverage is adequate? Note that we're talking about the structure and not the property here. Kevin is quoted throughout. 

“The real key to properly insuring one’s home is insuring the cost of rebuilding the home if it were destroyed in a total loss,” Gahagan says. “The local per-square-foot cost to rebuild is the critical factor here.”

We Asked Some Financial Advisers Everything You Want to Know About Money

Wondering how much you should be saving for retirement? Kevin Gahagan presents a pretty easy equation to find out:

“Take what it costs you to live today — both spending and taxes — and multiply this amount by 25. This would equate to a planned withdrawal rate of 4% over your lifetime. To this sum, you can add Social Security income which may allow for a lower withdrawal rate or can be a supplement to what you withdraw from your investments.”

Only a Third of Workers Make this Key Retirement Move

Research shows that the number of Americans saving for retirement has decreased, reports Kate Ashford for Forbes. Medical debt and preparing children for college top the list of reasons why Americans aren't utilizing retirement savings vehicles. Kevin weighs in with a tip to get the 401(k) ball rolling:

“For those employees who receive annual salary increases, the best way to begin is to dedicate one half of your salary increase to your 401(k) contribution,” says Kevin Gahagan, a financial planner in San Francisco. “You’ve not been used to making the increased salary, so saving a portion of it won’t be felt as readily.”

Strategies to Reap the Rewards of the Tax Loss Harvest

Wealth managers harvest tax losses through applying capital losses to reduce ordinary income, and writer Cyril Tuohy explains the process for InsuranceNewsNet. Kevin weighs in:

Capturing temporary losses to offset other realized gains “allows us to keep investment-related taxation at a lower current level,” said Kevin M. Gahagan, a financial planner with Mosaic Financial Partners in San Francisco.

“It needs to be acknowledged that this isn't a free lunch and it doesn't eliminate the eventual taxes that will come due,” he said. “This is a tax deferral strategy. It does defer the timing of when taxes may need to be paid.” / January 25, 2017

Hunger for Yield Sends Investors Afar

Emerging-markets bonds are a hot destination for ETF investors looking to avoid sapping the income component of fixed income (often impacted by low and negative rates).  Writer Ari Weinberg notes that such funds can feel more like a stock than a bond. Fixed income from developed markets is often used to reduce risk in portfolios. Weinberg quotes Kevin:

Emerging-markets fixed income has characteristics [and a volatility and return profile] closer to emerging-markets equity. Weinberg goes on to note that Mosaic manages $550 million in portfolios of mostly ETFs and looks at EMB within its 'alternatives' allocation.

What's the Best Retirement Drawdown Strategy for You?

Writer Amy Fontinelle interviews Kevin on retirement strategies:

“The fewer equities you have, the lower your withdrawal rate can be, Gahagan says. If your portfolio is 60% fixed income and 40% stocks, a 4% withdrawal rate is not realistic. But the solution is not an all-equity portfolio, either, because if there’s a severe recession and you’re forced to sell at a loss in the early years of your retirement, it can kill the sustainability of your portfolio, he says.”
