The private-sector Case-Shiller Index reported home values up 5 percent nationwide in June. The government’s own Home Price Index, however, reached a different conclusion.

According to the Federal Home Finance Agency, month-to-month home values fell 0.3 percent in June, and values are down by 1.7 percent from June 2009.

So, as a home buyer and/or homeowner in Stockton , by which valuation model should you make your bets?  Perhaps neither. 

This is because both the Case-Shiller Index and the Home Price have inherent methodology flaws, the most glaring of which is their respective sample sets. 

The Case-Shiller sample set, for example, comes from just 20 cities across the country — and they’re not even the 20 most populated cities. Together, the Case-Shiller cities represent just 9 percent of the overall U.S. population. 

That’s hardly representative of the housing stock overall.

By comparison, the Home Price Index tracks home sales everywhere — every city in every state — but it specifically excludes certain properties.  The Home Price Index does not track sales of homes for which the financing comes from agencies other than Fannie Mae or Freddie Mac. This means that as FHA loans grow in popularity, the pool of Home Price Index-eligible homes is reducing. 

The HPI ignores homes backed by “jumbo” loans, too.

Therefore, the “right” model for home values cannot come from national data at all — it can only come locally. Neither Case-Shiller nor the government has the tools to get as granular as a neighborhood like San Joaquin County. A real estate agent in the area does, however.

The best way to get a pulse for what’s happening in markets right now is to talk to somebody with good data.

With home prices holding firm and mortgage rates still dropping, home affordability is reaching new heights.

According to the quarterly Home Opportunity Index as published by the National Association of Home Builders, more than 72 percent of all new and existing homes sold between April-June 2010 were affordable to families earning the national median income.

It’s a slightly higher reading as compared to last quarter, and the second highest reading in the survey’s history.

As with all aspects of real estate, however, home affordability varies by locale. 

For example, 97.2% of homes sold in Syracuse were affordable for families making the area’s median income, earning the New York city its first “Most Affordable Major City” designation.  Indianapolis was the first quarter winner.

On the opposite end of the spectrum, the “Least Affordable Major City” title went to the New York-White Plains, NY-Wayne, NJ area for the 9th consecutive quarter.  Just 19.9% of homes are affordable to families earning the local median income, down 1 percent from last quarter.

The rankings for all 225 metro areas are viewable on the NAHB website but regardless of where you live, buying a home is as affordable as it’s ever been in history. Furthermore, because home values are in recovery and mortgage rates may rise, the market is ripe for home buyers in Stanislaus County.

All things equal, buying a home may never be this inexpensive again. If you were planning to purchase later this year, you may want to move up your time frame.

With home prices still relatively low and mortgage rates trolling near their all-time best levels, it’s no surprise that home affordability is extraordinarily high in Stockton and most U.S. markets.

According to the quarterly Home Opportunity Index as published by the National Association of Home Builders, more than 72 percent of all new and existing homes sold between January-March 2010 were affordable to families earning the national median income.

It’s the second highest reading in the survey’s history.

Of course, on a city-by-city basis, home affordability varies. 

In the first quarter of 2010, for example, 98.7% of homes sold in Bay City, Michigan were affordable for families earning the area’s median income and in Indianapolis, the percentage was almost 95 percent.

Indianapolis has held the top quarterly ranking for close to 5 years now.

On the opposite end of the spectrum, the New York-White Plains, NY-Wayne, NJ region earned the “least affordable” metropolitan area for the 8th consecutive quarter.  Just 20.9% of homes are affordable to families earning the local median income.

The rankings for all 225 metro areas are available on the NAHB website but regardless of where your town ranks, home affordability remains high as compared to historical values but it likely won’t last long.  Home values are recovering in many markets and mortgage rates won’t stay this low forever.

All things equal, buying a home may never come this cheap again. If you were planning to buy later this year, consider moving up your timeframe.

CNNMoney.com recently published its 2010 forecast and projections for home prices in the country’s largest metro markets. 

Listed as “Top 25″ and also comprehensively by state, CNNMoney.com’s home price forecasts puts Santa Rosa, California at the top of 2010’s home appreciation list and Hanford, California at its bottom.

The 10 cities projected for highest home appreciation in 2010 are:

1. Santa Rosa, CA : +6.0%
2. Cheyenne, WY : +4.7%
3. Kennewick, WA : +4.6%
4. Merced, CA : +4.4%
5. Bremerton, WA : +4.2%
6. Fairbanks, AK : +4.2%
7. Corvallis, OR : +4.1%
8. Tacoma, WA : +3.9%
9. Anchorage, AK : +3.8%
10. Bend, OR : +3.3%

The Pacific Northwest is the region most heavily-represented among price gainers. The Southeast and Middle Atlantic are most represented on the under-perform list.

However, just because a city’s homes are expected to appreciate (or depreciate) in 2010, that doesn’t mean that every home within its limits will follow suit.  Real estate cannot be grouped on a city level like CNNMoney.com tries to. There will always be areas in demand within city limits in which prices rise, just as there will be out-of-demand areas in which prices fall.

Real estate data can’t be grouped by city or even by ZIP code, really.

Real estate in Modesto is more local than that.

When we say “real estate is local”,  it means that every street in every town has a distinct set of traits that drives its home values. Homes that are one block closer to the train; or, homes that are facing north; or, homes that are made of brick. Each of these characteristics can affect a home’s desirability which, in turn, can affects its sales price.

National surveys can’t capture “essence” like this. They only report on the aggregate.

For local real estate data, look to established, publicly available websites and to active, local real estate agents.  Both will have data and insight that can help you.  National surveys often make for good headlines, but do little to help homebuyers find good value.
