Generating curb appeal and using model home staging techniques are better ways to spend your money than loading up on major home improvements when it's time to sell your home in any market.

Curb appeal and staging won't work, however, if your home is a wreck.

Both market conditions and your home's condition dictate what additional projects you should complete before you open your home to prospective buyers.

Seller's Market
In a seller's market, the rule of thumb is to leave most home improvements to the buyer.

You likely can't increase your sales price enough to cover the cost of the work and time and, second-guessing what the buyer will want in appliances, decor style and finishes could cost you the sale.

"Reduce your asking price so it reflects your older kitchen or bathroom instead of squandering time and money on a major remodeling job people might hate," says Ray Brown, San Francisco broker and co-author of "House Selling For Dummies" (IDG Books, $16.99).

One exception, however, is righting a wrong.

If you or the previous owner completed work on your home without a permit, make it right before you attempt to sell.

First, in many states, you and your agent are required to disclose known conditions that could affect the value or salability of your home. If you don't and a home inspector or appraiser uncovers unpermitted work, you could be liable for nondisclosure and the lender could stall the deal.

Ultimately, you could be required to have the local building officials inspect the work in order to obtain a permit. Before you get a permit you also may have to complete any unfinished work. In any case, if the work isn't to code, you could be forced to tear it out, especially if it's a safety hazard.

But that's not the worst of it.

"If, after close of escrow, the buyer discovers work completed without a permit and the local building department decides not to approve the work, a chunk of the home's value could become a legal issue. Any difference in value based on what was not permitted at the time of sale, becomes a point of litigation," said San Jose, California appraiser, Greg Stephens, who also serves as an expert witness on such cases.

All sellers should perform deferred maintenance repairs to fix or replace broken items and systems. Put the home and its components in good working order by replacing missing roof shingles and broken or cracked windows. Repair driveway cracks and straighten listing fences. Make sure doors, gates, lights, plumbing fixtures and other items are all working properly.

Buyer's Market
In a buyer's market, along with making certain your home and its components are all up to code, the idea is to give your home a marketing edge ? without over doing it.

The improvements you should perform aren't those that necessarily give you a return on your money. Instead, they should be largely generic, cosmetic improvements that enhance your home's functionality, efficiency and aesthetics ? all to give it a contemporary feel.

Often that simply means cleaning up and removing clutter. A new coat of paint, new carpeting, freshly manicured landscaping, updated fixtures, windows, doors and other touches will put your home in the best light.

If an inspection or appraisal turns up the need for major corrective work, say due to termite or moisture damage, leave money in escrow with instructions for the escrow officers to pay the contractors once they complete the work, says Brown.

Let the buyer select the contractors based on several fair bids and have the work done after the close of escrow to avoid a construction zone in your home while you are trying to sell it.

"If the buyer supervises the work, you won't incur liability for it and the lender knows the property will be restored to its proper condition, which enhances its loan value," says Brown.
