A construction company manager in his 50s bought a ranch-style house in a desirable neighborhood with the intention of renovating the place to flip it -- meaning he hoped to quickly sell for a profit.

Full of bluster and self-assurance, he embarked on a massive renovation program that involved gutting rooms and moving walls. The end product was good, but the whole renovation took vastly more time and funds than expected. Consequently, he lost money when he sold the place.

"By the time the house was ready for sale, the owner had spent nearly three months on the work and gone $25,000 over budget," recalls Ashley Richardson, the agent who eventually handled the listing.

Richardson, who's affiliated with the Council of Residential Specialists (www.crs.com), agreed that the construction manager's property needed updating. But he says the owner would have been well-advised to limit the remodeling work to minor projects to improve the home's appeal without costing a fortune. For example, he could simply have repainted the interior walls and replaced worn carpet rather than doing massive renovations.

This true story illustrates the risks of "over-improving" any home above neighborhood standards, says Mark Nash, author of "1001 Tips for Buying and Selling a Home."

"If you get into renovations involving too many bells and whistles, you never get a dollar-for-dollar payback when you sell," Nash says.

While many real estate markets are now strong, others are still sputtering. Because of that, Nash emphasizes the need for forethought and guidance from local experts before embarking on pre-sale remodeling.

However, Nash cautions that would-be sellers who are too stingy to pay for essential improvements, such as a shabby roof, face their own set of difficulties.

A dated-looking kitchen is also a huge negative for buyers, says Nash, noting that it's essential to replace countertops that are worn or scratched. In addition, he says sellers should replace an old kitchen floor. But in most cases, he argues against large-scale kitchen renovations that involve tearing out cabinets or installing professional-grade appliances.

Here are a few tips for sellers on how to avoid excessive pre-sale work:

-- Seek the counsel of local real estate experts before you renovate.

"It's always unwise for sellers to commit to remodeling before they discuss the work with real estate people who know their area. They're the ones who can tell you what your market will bear and what it won't," Nash says.

He recommends you contact three local agents for advice on which home-improvement projects are truly necessary. Most well-established agents will visit your house and advise you even if you don't intend to sell for another three to five years.

As an added benefit, he notes that many agents maintain a database of reliable contractors.

-- Limit your renovation projects to neighborhood norms.

Tom Early, a real estate broker who was twice president of the National Association of Exclusive Buyer Agents (www.naeba.org), says current homebuyers won't pick up the tab for any renovation work that raises a property above neighborhood standards.

What sort of upgrades constitute "over-improvement"? For example, you wouldn't want to install high-end, designer light fixtures in a neighborhood of starter homes. By the same token, you wouldn't want to construct a three-car garage in a neighborhood where most houses have no garage at all.

-- Don't be afraid to cancel any projects that prove too expensive.

If you think your contractors are going over the top, Nash says it's better to cancel projects before they're finished than to overspend on work that will cost much more than expected.

"For example, most buyers don't care if they get super appliances in the kitchen or laundry room. It's the basic house and floor plan they're looking for and not high-end elements in every room," Nash says.

As he points out, real estate agents often recommend the use of less expensive products than are suggested by contractors. For example, you don't need to spend your money on top-of-the-line carpeting when a mid-level grade will do just as well.

"It's true that bailing out of work with a contractor can cost you a penalty. But doing so might still be the wise course if a project has become too ambitious," Nash says.

-- Avoid rushing the renovation process.

As Nash notes, many home sellers realize too late that a thoughtlessly executed remodeling program can hit their wallet hard. That's why he recommends you write on an index card the basic elements of a carefully considered plan. Have that index card handy as a reference guide when contractors come over to do estimates.

"Don't let the contractors dissuade you from your goal of staying within your budget. What you need is a sound plan. Then stay true to that plan until it's all done," he says.

Steven Sass is an economist and an expert on retirement planning. Yet he acknowledges that he and his wife, a fiction writer, are uncertain about their retirement housing plans.

Both agree they'd like to downsize from their sprawling two-level contemporary to a smaller, single-story space. Both also wish to stay in the Boston area, where their four grown children and three grandchildren reside. But beyond that, they're conflicted.

"I'd like an urban setting, but my wife wants something more bucolic," says Sass, a program director at Boston College's Center for Retirement Research.

Though the couple is still at least four years away from retirement, Sass says they're already "sniffing around" in search of the ideal retirement setting for their wants and needs. They're also reviewing their financial plan to ensure that the next home they buy will be affordable. And he advises other retirement-age downsizers to do the same.

When reviewing options for downsizing, he stresses the need to take a methodical approach that factors in the expense of selling one home and moving to another.

"Downsizing -- which means moving to a less expensive home not just a smaller one -- usually increases your income by reducing your housing costs. But remember that the cost of downsizing usually runs about 10 percent of the value of your house," Sass says.

People downsizing can't afford to ignore financial issues, says Fred Meyer, a long-time real estate broker.

He says retirees are often happier living in a modest home while pursuing their post-work dreams than in a ritzier place elsewhere. The good news is that those with such common interests as tennis and golf can find these activities in many locations. But others, such as opera aficionados, have a narrower range of choices.

Leo Berard, charter president of the National Association of Exclusive Buyer Agents (www.naeba.org), says it's crucial to plan ahead for a move in retirement.

"In the best of all possible worlds, you'll start searching for the ideal place to live at least two years prior to retirement. There's no one-size-fits-all solution to housing for your later years," he says.

Here are a few pointers:

-- Think through the implications of moving near your grown children.

Many retirees yearn to see more of their grown children and grandchildren. And they're willing to consider a distant move to do so.

"The kids are a powerful draw for lots of folks. But you need to think through the implications of living very close to them," Berard says.

Perhaps you relish time with your offspring. But how would you feel if asked to take on the role of regular baby sitter for young children?

"Even if the kids' mom and dad don't intend to make you their primary caregiver, they could start to rely on you if good child care is expensive in their area," Berard says.

It's also possible that your adult children will be less than thrilled having you live in the same neighborhood. To be sure they're OK with the idea, Berard recommends you have a candid conversation before committing to the move.

-- Explore a retirement "paradise" to see if you'd truly like it.

Fancy websites and glossy ads tout the idea of moving to faraway counties for retirement, where it's said the scenery is beautiful and the cost of living low.

But in spite of all the hype surrounding such utopian retirement settings, many who choose them find them less than satisfactory, says Eric Tyson, co-author of "Home Buying for Dummies.

"The novelty of unlimited recreational activities ... can wear off fast," he says.

As Tyson notes, retirees living in an isolated resort area often feel disconnected from the everyday lives of friends and family members -- even if they come by on vacation from time to time.

What's the best way to determine if a resort community would be a good place to retire?

"If possible, take a lengthy vacation there or rent a place there for a month or two," he says.

-- Examine your financial situation.

Do you lack substantial retirement savings and expect to rely on proceeds from the sale of a large family home in your future years? In that case, Berard recommends you plot a strategy with a trusted financial adviser or accountant before making any sudden move.

"Getting professional advice is particularly relevant in this era of rapidly changing home values. You want to carefully time the sale of your present property before you buy another one," he says.

Berard says it's important to give serious thought to the level of mortgage debt you're willing to carry into retirement. For most people, a comfortable retirement means relief from large house payments.

"After downsizing, it's always great to be free and clear of all mortgage debt. That's because cost of living factors are huge in retirement," he says.

-- Seriously consider buying in the same general area where you now live.

For more than 20 years, Berard has helped retirees sort through their housing options. And experience has taught him that most do best when they live within a 30-minute drive of their former home.

He says that retiring to a distant location can be an especially poor choice for those who are actively engaged in volunteer work with charitable or religious groups within the area where they've lived for many years.

"The odds are, you'll find retirement a lot more meaningful if you stay where you've built a strong support network of family and friends," Berard says.

Home price appreciation has slowed recently in many neighborhoods. But a shortage of available properties is still leading to multiple bidding situations in especially popular areas. And that can result in buyers feeling pressured to bid on a place before they're absolutely certain it's the right one.

"Most people who get caught up in bidding wars feel an urgency to buy because they must move soon or because they've already lost a house to other bidders and don't want to lose again," says Eric Tyson, a personal finance expert and co-author of "Home Buying for Dummies."

But the risks of buying prematurely -- before you're certain a neighborhood and particular property are right for you -- are numerous. One major risk is that you'll lock yourself into a lifestyle that proves uncomfortable.

Multiple bidding scenarios can also result in paying too much for a property and regretting it later, according to Tyson.

"Sometimes on the advice of their listing agent, home sellers will price a property just very slightly below its market value in order to engender excitement and create an auctionlike situation involving buyers," Tyson says.

"Just because a house is perfect for other bidders doesn't mean it's right for you. The problem is that when there are multiple offers, you never know who you're bidding against or what features are motivating them," Tyson says.

Are you planning a major housing move? And do you wish to take a methodical approach to the change -- giving yourself several months of lead-time to research your options before buying your next property?

If so, you may be among the wisest of home purchasers, Tyson says.

"Like making a major career change, a decision on housing can have a huge impact on your quality of life for years. And the wrong decision can come with significant financial penalties," Tyson says.

Here are a few pointers for long lead-time buyers:

-- Look for an experienced real estate agent to help guide you.

Those who are relocating, whether for a job change, a retirement move or any other reason, are well advised to search for an agent who has years of experience selling homes in any community they're considering, says Tom Early, a real estate broker who twice served as president of the National Association of Exclusive Buyer Agents (www.naeba.org).

"With rare exceptions, it's a mistake to accept a rookie. The wisdom that comes from experience is very valuable in helping you get a realistic feel for your new turf," Early says.

-- Watch out for any agent who tries to pressure you into buying too soon.

It's true that agents are compensated on commission, and therefore don't make any money until a sale goes through. But reputable ones won't try to rush you into a purchase before you're ready, Tyson says.

"It's an enormous red flag if an agent starts pressuring you," he says.

Of course, it's unfair to ask an agent to spend multiple weekends over several months showing you property unless you're progressing toward your objective of finding the best available neighborhood and home in your price range. Even veteran agents occasionally have to cut ties with clients who've looked continuously without any serious intention of buying.

Still, as Tyson says, it's not unreasonable for serious buyers to spend up to six months or longer doing intermittent, yet focused, outings with an agent before committing to a property purchase in an area that's new to them, Tyson says.

-- Enhance your search with visits to open houses.

If you're a long lead-time buyer planning a major housing change -- such as a move from a suburban house to a downtown high-rise condo building -- you needn't rely solely on your agent to help you sort through your choices. You can do much of the footwork on your own, Early says.

"By visiting open houses as you start your due diligence, you can get a general feel for the choices open to you. Especially at the beginning, narrowing your options can be extremely helpful," he says.

Many open houses are well advertised with street signs. If you're considering condos, however, Early suggests you make doubly sure you consult local newspaper ads or online resources for open-house details.

-- Ask questions of residents of areas you're considering.

As you develop a short list of housing alternatives, some of the most useful sources of realistic information are those who live and work in the areas you're considering.

"People usually know their neck of the woods as well as any professional who sells property there. And most neighbors are happy to tell you the candid truth about their neighborhood, including any traffic problems, school issues or noise situations," Early says.

What's the best way to approach neighborhood residents? Early recommends you walk through a community on a weekend afternoon when many people are likely to be out in their yards. Tell them you appreciate their neighborhood and are considering a move there. Then politely open a conversation with a few questions.

"If people are unwelcoming, you can bet that community is an unfriendly one you'll probably want to cross off your list," Early says.

Those considering a condo building may find it harder to interact with residents, though people may talk to you as they enter or exit your complex. Alternatively, an agent who lists property in the building may also line up contacts for you.

-- Don't rule out a short-term rental.

Most people who've owned a home previously are resistant to taking a rental, even for a short period, until they've had enough time to explore neighborhoods in a region that's new to them. But Early says renting for a few months might be a good idea for those who wish to explore alternatives before submitting an offer to buy.

"Granted, it's unpleasant to throw away money on rent when your real intent is to buy -- even if you're only renting for a brief period. But renting for a short time is a heck of a lot better than rushing into the wrong housing decision," Early says.
