NVR (NYSE: NVR) is probably the healthiest of all the major home builders. In fact, the company hasn't taken a single annual loss yet. The company reported a quarterly loss for the fourth quarter of 2008, but all of the other quarters have recorded a profit.

Even though NVR is a fairly small company (market value of nearly $4 billion), the stock carries a very high price. The shares are currently over $660 a piece, which is even higher than Google.

The past few years haven't been what you might call a happy time for shares of home building stocks. Consider that the Homebuilders Exchange-Traded Fund (NYSE: XHB) plunged from $40 per share in early 2007 to just $8 per share earlier this year.

Since March, however, things have improved. There are signs that the housing market is getting back on its feet -- or at least, declining less slowly. Existing home sales recently registered their biggest gain in more than a decade. Seasonally-adjusted single-family building permits are up 27% since bottoming in March, while single-family housing starts have increased five straight months and are up 36% since March.

Most investors got slammed last year, down 50% or more in their investments. Didn't matter if they owned stocks or real estate, they got hammered. Many have to start over. And if they're near retirement, it's scary. Years of patient investing wiped out, gains that were made over a long time disappeared frighteningly fast.

But now it's time to begin fresh, to rebuild. What's the safest way to regain some or all of the losses without suffering another wipeout?

"The economic crisis began in the housing sector and will likely end there," says Stephen Leeb. In his top-notch The Complete Investor he takes a contrary look at two homebuilders.

"Though my view may sound contrarian to a fault, a close look at the housing market, especially given recent government actions, suggests a recovery will happen sooner rather than later and be stronger rather than weaker.

"When home prices decline, buyers pull back, afraid of buying too soon. This leads to further declines and further buyer reluctance. No surprise, then, that housing starts have fallen dramatically.

"Meanwhile, consumers, who had been borrowing money based on the value of their homes, found this source of credit drying up, which dealt a further blow to the economy.

"It is a vicious circle indeed. Ultimately, though, it will almost certainly end with more willing lenders and a stronger housing market as the huge amounts of money being flooded into the system start boosting balance sheets of potential lenders.
