On a frosty February day five years ago, a retired Iowa nurse decided to sell her ranch-style house in favor of a condo in sunny central Florida.

But the move proved mistaken. The nurse missed her friends back home. Her taxes and condo fees were higher than expected. What's worse, her property lost value. So, she intends to sell soon and buy a place near her grown son in Des Moines.

"It's a U-turn for my mom. But I'm sure she's making the right decision. Now we're just focused on helping her make a graceful transition," he says.

Gradually declining property values are now a reality in some communities, including in Florida, where condos are experiencing more slippage than detached, single-family properties.

In some cases, the reasons for this gradual valuation declines involve "higher inventory, less migration to the area and sellers overpricing the homes," says Brenden Rendo, a mortgage lender and real estate adviser in Central Florida, in an article by Kiri Blakely on Realtor.com, the online real estate website.

The nurse making the U-turn is determined to avoid the pitfall of overpricing her two-bedroom unit. She's putting a greater emphasis on a speedy sale to hasten her return to Des Moines.

"Sometimes, moving on with your life is more important than getting every last penny out of a deal," the nurse's son says.

All this is not to say that her move back to Iowa from Florida will be easy for the widowed 71-year-old. But her son's unwavering commitment to assist should make a major difference.

Her are a few pointers for those seeking to support elderly parents on a housing move:

-- Respect your parents' attachment to their home.

Some seniors, like those with a history of moving for military work or corporate transfers, find it relatively easy to prepare their homes for sale. But those who've stayed put usually have a harder time letting go of their accumulations.

"Young people are accustomed to casting off possessions when they move. After all, they were raised in a country flooded with cheap imported goods. But their grandparents weren't raised that way," says Joan McLellan Tayler, a longtime California real estate broker.

For seniors, sorting through possessions can be exhausting.

"What's a treasure and what's junk? Separating items into those categories can be tremendously tedious," Tayler says.

But while the adult children of elder parents can be very helpful in a housing transition, Tayler says it's unwise for them to become involved in the sorting and culling process.

"That can result in heated arguments that are painful for all concerned," she says.

Instead, she recommends that senior home sellers engage the help of a professional organizer. One source for referrals is the National Association of Productivity and Organizing Professionals (napo.net). For a lesser fee, your parents can likely find an energetic college student or recent grad by posting an online ad.

-- Assure your parents you'll respect their prized possessions.

"Of course, your parents are entitled to keep the most valued parts of their legacy. And it's not up to you to decide what's most important to them," says Diana Gaydon, a real estate broker based in Portland, Oregon.

One way to help smooth the transition for your parents is to guarantee you'll safeguard their valuables during the interim period in which their home is shown to the public.

"For example, you might tell them you'll take those coveted photos they have hanging on the wall and place them in a nice box on your piano until their house is sold," Gaydon says.

-- Show empathy in helping your parents dispose of excess possessions.

Conducting an estate sale to break up a household might sound like a good idea. After all, the professional firm holding the sale will give your parents a percentage of the revenue they bring in.

But the unsentimental manner in which such a sale is conducted could easily hurt your parents' feelings. It can be painful to overhear strangers haggling over the price of items you've owned and valued for decades, Tayler says.

As an alternative, she recommends you ask your parents for the names of their favorite charities and arrange to have their giveaways taken there. (Valuable antiques and art can be sold through a dealer or an online company such as eBay.)

"Donating to a charity you believe in can be a positive experience," Tayler says.

-- Be diplomatic when addressing your parents on needed home updates.

Those who've lived in the same home for a long time are often very comfortable with their decor -- no matter how dated -- and think prospective buyers should feel the same way. But their grown kids typically agree with the listing agent that the home should be updated to more contemporary standards before it goes on the market.

The problem is that you could face a lot of resistance if you try to push your parents into replacing their still-functioning avocado-green refrigerator. Likewise, they might rebuff you if you demand that they have their 25-year-old lavender carpeting torn up and replaced with a neutral beige carpet.

Instead, try quiet reasoning and persuasion in hopes of convincing them to follow your recommendations—and those of their listing agent.

"Never attempt to belittle or shame your parents into the home improvements needed for a successful sale. That can backfire big time," Tayler says.

A Southwest airlines supervisor was just 20 when she married and had her only child, a son who's currently a college sophomore. Now divorced, the woman is ready to sell her five-bedroom brick colonial in the Dallas suburb of Frisco.

"I'm not yet old, but I see no reason to hang on to this McMansion I inhabit. I want a smoother, simpler life in a condo close to the Southwest headquarters. This move will cut my taxes and spare me lots of cleaning and upkeep," she says.

The woman is excited about the possibilities that could come from her downsize move.

"More important than a showy home is the freedom that comes from living smaller. Once I sell, I'll have more leeway for travel and hobbies, like my genealogy and book clubs, as well as my Zumba and spin classes," she says.

Most downsizers are either retired or nearing retirement. But like the Southwest supervisor, an increasing number of middle-aged owners are also eager to divest themselves of an oversized McMansion, according to Zillow, the Seattle-based real estate firm.

"American homes have shifted from status symbols to sanctuaries. Buyers are no longer chasing the biggest footprint of the glossiest finishes. Instead, they're seeking homes that reflect who they are ... and what they value," says Amanda Pendleton, Zillow's home trends expert.

Pendleton notes that at the height of the building boom -- roughly 2002 to 2006 -- McMansions were constructed all over the nation, but especially in Sun Belt metros. Many featured giant Tuscan-style kitchens with dark cherry cabinets and speckled granite countertops, as well as big bathrooms with jetted tubs and three-car garages.

But these days buyers are less interested in impressing guests and more interested in how a home supports their lives in practical ways, such as low energy costs.

Sellers like the Southwest supervisor are aware that many of their home's McMansion features seem dated to current buyers. That's why it's important they choose a listing agent who will highlight the positives, like energy-saving replacement windows and kitchen pantries.

"It's typically not cost-effective to do major renovations to get a dated property sold. But you can stress work you've already completed. This could include a new roof or replacement appliances in the kitchen," says Joan McLellan Tayler, the longtime owner of a California realty brokerage.

"Look for a listing agent who knows what buyers in your area prioritize," Tayler says.

Here are a few pointers for sellers:

-- Seek experience when choosing a listing agent.

Tayler says too many sellers take a casual approach to picking an agent, noting that some make the mistake of hiring a relative, a friend or a young agent looking to get started.

"A lot of the sellers fail to understand that even in a strong market, it takes complex skills to do a great job selling real estate," she says.

Tayler recommends that sellers opt for an agent with experience in handling lots of different deals. Those with a track record are most apt to sniff out problems before they happen.

If for personal reasons you're determined to choose a newcomer, she suggests you ask that agent to share the listing with an established pro from the same office.

"With two agents on your side, you'll benefit from both their strengths," Tayler says.

-- Make sure that prospective buyers are financially qualified.

Sharp sellers are careful to check the financial standing of would-be purchasers.

"Who wants a deal to fall through because the buyers lack the wherewithal or credit to get it to the finish line?" says Eric Tyson, a personal finance expert and co-author of "House Selling for Dummies."

Before accepting an offer, sellers should insist on seeing a genuine preapproval letter from a known lender, Tyson says. This should establish that the prospective buyers have had their credit checked, their employment confirmed and their assets verified.

In addition, prospects can be asked to supply other details about their creditworthiness, such as their credit scores. The most common of these, known as FICO scores, range from 300 to 850. The higher that number, the more likely borrowers are to get the loan they need to close the deal.

"To avoid insomnia, look for buyers with scores of 700 or above," Tyson says.

Bidders can obtain reports on their credit scores from a website of the Fair Isaac Corp (myfico.com).

-- Get ready for issues that could arise during an inspection of your home.

In all sorts of neighborhoods -- including very popular ones -- many purchasers exercise their right to a home inspection. And many use the process as leverage to renegotiate the deal.

"Even in a tight market, if the inspector finds substantial defects in the house, the buyers could attempt to use these findings to revisit the terms of the deal," Tyson says.

Homeowners should never try to talk buyers out of a home inspection. But smart sellers will consider paying for their own inspection even before the property goes on the market.

"The person you hire for a presale inspection is unlikely to find all the same small problems that the buyer's inspector locates. But both should spot the really major problems, like a failing roof or electrical system," Tyson says.

"Knowing the problems that lurk in your house is especially important if the place is more than 10 years old," he says.

A married pair of social workers are approaching retirement and hope to soon sell their house in Brentwood, Tennessee, a ritzy suburb of Nashville. For years, the property values there have escalated. But as they approach the market, the couple are taking no chances on the sale of the six-bedroom colonial revival house they bought in 1999.

“We aren’t big salary people. We couldn’t imagine buying a house in our neighborhood now. Yes, people want to live here. But the local market is starting to weaken. So, we don’t want to push our luck,” the husband says.

As he notes, for-sale properties are lingering unsold longer than before -- with days on market increasing. What’s more, some pending sales have flopped after buyers backed out in search of better deals.

“These failed listings are cautionary tales for greedy sellers who list too high. We don’t want to get humbled because we’re in a hurry to retire,” the husband says.

Brentwood is hardly alone in experiencing an increasing number of canceled sales. In December alone, about 40,000 home purchase agreements were canceled in the United States, says Chen Zhao, head of economics research at Redfin, the national real estate brokerage.

“High housing costs and rising inventory have made homebuyers more selective,” Zhao says.

As she explains, buyers seeking to cancel often cite a home inspection report that finds significant problems with the property, such as a malfunctioning HVAC system or a leaky roof. But the cancellation might truly be due to fears of overpaying.

Daniel Harbuck, a real estate broker and the author of “Unlocked: Homebuying Secrets No One Has Ever Told You,” doesn’t know the Tennessee social workers in this true story. But he agrees that careful pricing is in the sellers’ interest.

“Your home’s price tag? It’s the ultimate first impression. Nail it, and the buyers come running. Flub it, and watch your profits vanish. In this real estate game, the price is your power move,” Harbuck says.

Here are a few pointers for home sellers:

-- Look for an assertive listing agent to represent you.

“In all markets, selling a home to make an immediate move is anxiety-producing, and all the more so at a time of economic uncertainty,” says Stacy Berman, a longtime real estate agent in Maryland.

She recommends you search for an agent with extensive experience selling properties in your community. Another key is to rely heavily on referrals from neighbors and friends who’ve sold in the same area.

Don’t know anyone from whom to seek referrals? Another approach is to call the managing broker of a major realty office nearby. Ask the broker to refer you to an experienced listing agent with a substantial track record selling homes similar to yours in your price bracket.

-- Factor in your competition before pricing.

Eric Tyson, a personal finance specialist and co-author of “House Selling for Dummies,” says that prior to accepting any pricing recommendation, all sellers should do at least a nominal amount of research.

“Ask your agent for a list of properties near your home that have sold recently. Then get in your car and drive by these homes, noticing how they compare with your own,” Tyson says.

If your drive-by tour raises questions in your mind about whether your listing agent is suggesting too high or low an asking price, request a justification for the recommended price. Then reach your own conclusion.

“At the end of the day, it’s the owners, not the agent, who have the final say on pricing,” Tyson says.

-- Weigh a plan to price slightly below others nearby.

Remarkably, sellers in a desirable area can often receive more for their property if they price it just slightly below its apparent market value.

“Pricing a little lower than the competition can generate excitement. More people are likely to bid if they perceive the property to be a good value. And this can create an auction effect that could help you at the bottom line,” Tyson says.

-- Try to delegate many of your presale chores.

Sellers typically spend several months or more preparing their property for market. They cull through belongings, paint wherever needed and clean exhaustively.

But if you’re selling under time pressure, chances are you’ll have no more than a few weeks to get the home in showing condition.

One obvious way to cut back on your home-prep time is to hire contractors for work you might normally do yourself. Tyson says that sellers working against a tight deadline can get a lot more accomplished in a shorter time if they delegate.

-- Create a contingency plan for your property’s sale.

Sometimes even a home that’s in good condition and correctly priced will fail to sell in a reasonable time for reasons hard to determine.

To avoid panic in this situation, Tyson recommends that people who must sell in a hurry develop a plan B for coping if the process takes longer than expected, compelling them to move before their place is sold.

Perhaps you’ll arrange for a trusted family member to take responsibility for your home sale. Or maybe you’ll want to “buy” time by renting out the house for six months or so.

“You’ve got to look at the big picture. What matters is not only your financial well-being but also your emotional health,” Tyson says.
