In most cases, the loan modification decision on a modification is not made by the firm that owns the loan. It is made by a firm servicing the loan under contract to the owner. The owner could be a single lender, or it could be a group of investors who own pieces of a mortgage-backed security collateralized by a pool of loans.

Whoever owns the loan, the servicing firm is contractually obligated to find the solution to loan modification payment problems that will minimize loss to the owner. If the lowest-cost solution is a contract modification, that's great -- everyone involved prefers a modification instead of a foreclosure. But if a foreclosure would generate lower costs for the owner, the decision will be to foreclose. The cost of foreclosure to the borrower does not enter the decision.

Yet the decision is far from cut and dried, and it can be materially affected by whether and how the borrower presents his case. I discussed this issue with a lawyer who represents borrowers seeking loan modifications. Our combined observations:

Equity: Perhaps the most important factor affecting the modification decision is the amount of equity the borrower has in the property. If the borrower has enough equity in the property to pay any deferred interest plus foreclosure expenses, foreclosure is almost bound to be the lower-cost solution loan modification .

Equity depends on property value, which the borrower is much better positioned to know than the servicer. The borrower knows or can easily find out how many houses in the neighborhood are for sale and what the trend has been in recent sale prices. In a weakening market, it is easy for the lender to overestimate value, and the borrower must prevent that.

Moral hazard: Servicers fear that if they are liberal in granting modifications, borrowers who don't need a modification will seek one anyway. They protect themselves against this by entertaining modification proposals on a case-by-case basis, while placing the burden of proof on the borrower loan modification .

Borrowers must accept the burden of proof. In addition to the data on property value, they need to document that they cannot afford the payment increase that is pending, and they must document loan modification what they can afford.

To do so, borrowers should calculate their total debt ratio: the sum of mortgage payment, other debt payments, property taxes and homeowner's insurance as a percent of their gross (before tax) income to qualify for a loan modification.

This number should be calculated as it stands now and as it would be after the rate adjustment. It should also be calculated to demonstrate what the borrower can afford. On the last, he suggests that a servicer may be willing to accept 45 percent as a reasonable maximum.
