More than 130 million Americans will receive tax rebates this year as part of Congress’ $168 billion economic stimulus package.

Payments begin in about two weeks and range from $600 for individuals to $1,200 for couples, plus an additional $300 per child.

Not everyone is eligible for a full rebate, however.

For single filers earning more than $75,000 and joint filers earning more than $150,000, the tax rebate is reduced by $50 for each $1,000 of income beyond the limits.

An individual with no children, therefore, will not receive a tax rebate if income exceeds $87,000 annually. The IRS provides a tax rebate calculator that can help make sense of the math.

For tax filers using direct deposit, the rebates will be paid based on the last two digits of the social security number:

• SSN ending in 00-20 will arrive May 2
• SSN ending in 21-75 will arrive May 9
• SSN ending in 76-99 will arrive May 16

For tax filers using paper checks instead of direct deposit, payouts begin a little bit later on May 16 and extend through mid-July. The IRS makes the exact dates known on its Web site.

For late income tax filers, the IRS send rebate checks about two weeks after the returns are processed, but not before the regularly scheduled date.

The National Association of REALTORS released its Existing Home Sales report for March 2008. An “existing home” is one that is not considered new construction.

A sub-headline in the report showed that the median sales price of all homes sold in March increased by 2.5 percent to $200,700.

But don’t assume that the housing market is improving because of a statistic like that because in the field of Statistics, median is just the “middle” in a group of numbers.

With respect to the Existing Home Sales, the median sales price is the price point at which half of all homes sold went for more, and half went for less.

If more homes sell in high-priced San Jose, CA than in low-priced Youngstown, OH, for example, the median will be skewed to the high-side. The reverse is true, too.

Median sales price make for good headlines, but it does nothing to talk about the local market and that’s where real estate is bought and sold.

As mortgage lenders limit how much money they will lend and to whom, co-signing home loans is growing in popularity.

“Co-signing” a home loan is when a third-party — usually a parent or relative — promises to make repayments to the bank in the event that the borrower falls behind on his obligations.

Money experts usually advise against co-signing notes because of the long-term financial risks, but people still do it for a number of reasons including “wanting to help”.

If you’re thinking about co-signing a home loan for a friend or loved one, it’s important to consider the implications of sharing credit with another person.

The four questions below may help you with your decision:

1. Why can’t the borrower get approved on his own? It is because of poor credit ratings? Lack of income? History of foreclosure?
2. If the borrower stops paying the mortgage, can you afford to make the full payment due each month?
3. If the borrowers defaults on the mortgage and doesn’t notify you, how will a foreclosure on your credit rating impact your family finances?
4. When the co-signed loan appears on your credit, will the debt load prevent you from getting approved for your own loans in the future?

Not only can a co-signed home loan create serious financial burdens, but it’s a long-term commitment, too.

Once the note is co-signed, the only way to separate the signers is terminate the note entirely. The two ways to accomplish that are to remortgage the home out of the co-signer’s name, or to sell the home and retire the debt.

Co-signing on a mortgage is not “bad” but bad things can happen should the primary signer face personal and/or financial difficulties. Before agreeing to share credit, consider the implications should something go wrong.

The S&P 500 added 4.3 percent last week — more than during all of 2007 — in what was a good week for the economy and a bad week for mortgage rate shoppers.

After Friday’s close, mortgage rates were higher by as much as 0.375% versus the Friday prior. This reversed a trend of falling rates for Americans.

In recent weeks, mortgage rates had been falling as investors fled risky stocks and parked their money in the bond markets.

A trading pattern such as this one is sometimes called “Flight to Quality” and it creates a high demand for all types of bonds. When bond demand is high, bond prices increase and that drives bonds’ relative rates of return down.

Over this past week, however, the Flight to Quality unwound.

Investors saw opportunities for stock market gains and funded stock purchases by selling bonds that they had amassed over the weeks prior. This created an imbalance of bond supply versus bond demand and that caused bond prices to fall.

Naturally, the corresponding rates of return on the bonds rose.

And so, because mortgage rates are really just “rates of return” on mortgage-backed bonds, we can understand why mortgage rates suffered last week as the stock markets were gaining.

It wasn’t anything fundamentally bad in the bond market as much as it was the attraction of stock market gains.

This week, there won’t be much economic data to cross the wires but 160 companies in the S&P 500 will report their earnings. This could have a broad impact on mortgage rates, similar to last week.

If corporate earnings are stronger-than-expected, expect mortgage rates to continue higher as additional monies flow into stocks at the expense of bond markets.

In the world of real estate, Days On Market is the number of days between when a home lists for sale and when it goes under contract.

It is often abbreviated as DOM.

Average Days on Market is a similar statistic but instead of applying to one home in particular, it applies to all homes in a given neighborhood, ZIP code, or city.

Average DOM is calculated by adding the number of days for which every listed home in an area was available for sale, and then dividing that number by the total number of listings.

In a buyer’s market, Average Days On Market is often elevated. This is because homes don’t sell as fast as during a seller’s market when the Average DOM can be quite low.

For buyers and sellers of real estate, Average Days On Market can be a strong indicator of home prices. When Average DOM falls, home prices tend to increase.
