As long as sound underwriting standards are applied,  lenders should not be afraid to add a little spice to the menu of mortgage   offerings, mortgage securities investors say.   
For instance, Paul Geyer, a portfolio manager with Chubb Corp. is  intrigued by the prospect of securities backed by "transportable" loans in   which borrowers can transfer their mortgages to a new property when they   move.     
  
These securities, Mr. Geyer said, would potentially be less volatile  than many other mortgage securities because they would not prepay quickly. 
Mr. Geyer raised the suggestion during the Secondary Marketing  Conference of the Mortgage Bankers Association. The session offered a rare   chance for mortgage securities investors to speak their minds directly to   mortgage bankers.     
  
And, for the most part, lenders liked what they heard. "We want to take  this information back to originate products that provide more value for   us," said Carroll Justice, senior vice president of FT Mortgage Companies,   lender in Dallas.     
Indeed, lenders stand a better chance of making more money from loans  when they know investors are willing to purchase them. 
The investors at the session-ranging from pension fund chiefs to  investment banking managers-said variety was a key word because standard   mortgage-security returns are less attractive than they were in the past.   
  
This is because yields have been driven down through large scale  securities purchases by Fannie Mae and Freddie Mac, and hedge funds that   can capitalize on smaller spreads, said A.L. Goduti, vice president with   Scudder, Stevens & Clark Inc.     
More varied securities can offer better returns, Mr. Goduti said. He and  other investors said they were willing to accept securities backed by   innovative lending strategies like 125% loan-to-value ratios-because of   lenders' track record for prudent underwriting. But, the investors said   they would likely demand additional return for being the pioneer purchasers   of these newer securities.         
"I'd say to the mortgage industry, 'Be creative,' " said Richard Piket,  portfolio manager for the San Francisco Public Employees pension fund.   "Present structures to us through which we can take advantage of return   opportunities."
