Portable mortgages are an idea that makes sense...maybe. The concept is simple. You get a home loan at a 30-year fixed rate. If you lock-in when rates are low, you keep that rate for the life of the loan and transfer the loan to a new property.
Borrowers would love it because it makes them feel that the loan they "earned" stays with them forever. Secondary markets (the ultimate purchaser of most loans) and banks, won't love this idea.
Portable mortgages are available in Canada. E-Trade Financial experimented with this loan product in 2003. They charged borrowers a rate premium of .375% to guarantee that portability. That means that if the "market rate" was 5.5% in 2003, the borrowers who optioned to take the portable mortgage, received a rate of 5.875%.
The rate premium was charged to appease the secondary markets by providing them the extra money to hedge the interest rate risk. The interest-rate risk for the investors could be hedged through mortgage derivatives or a collared options strategy. I'm not exactly certain how that strategy will work so I'm asking Pat Kitano to comment; he was a capital markets guy on Wall Street (I was a consumer markets guy) so he might have an interesting take for us money geeks.
What are some of the problems ?
WACC is the most obvious problem for the consumer. if you have a $200,000 mortgage at 5.875%, and you want to transfer $200,000 in equity to a $500,000 home, you'd have to obtain a $100,000 second mortgage at 8.5%. This would give you a WACC of 6.75%. That's about .375% higher than the current market for a 30 year fixed rate, conforming loan.
Downsizing movers would probably not benefit. I have to think that a 20% equity position will need to be maintained. reducing the loan amount would severely hamper the secondary market's ability to hedge that interest rate risk so they would most likely disallow such a transaction.
Not all county recording offices are automated. The County of Philadelphia is still recording deeds like they did in 1963 while Maricopa County has been automated since the early 90s. This makes it difficult for a lender to perfect a proper lien on the new home. Moving from Philly to Phoenix shouldn't be a problem but the reverse could be catastrophic for the lender.
Mortgage originators will HATE this idea. Over 70% of the home loans in the country are originated by mortgage brokers. Brokers make no money on the servicing of the loan and would most likely resist the adaptation of this new product. I suppose brokers could charge a slight premium in origination fees to recapture that lost future income.
Conclusion:
I'm predicting that a portable mortgage, while a unique marketing tool, would ultimately not be of benefit to most consumers. In today's new real estate paradigm, equity harvesting offers more benefits to the consumer than the old "stay and pay" approach of the Depression Economic and Boomer Economic paradigms. Its a fun topic to bounce around but the practical applications just don't make sense.
