I purchased my condo using the MHP soft second loan program in 2003. Since then I have married and moved into my husband's home. The loan has a residency requirement, but I can't find anywhere where it says what you are to do if you are no longer going to reside in the property. I also read one of your previous post that said "a soft second mortgage is typically one that need not be paid back." and you suggested caution with refinancing. How is it that the soft second does not need to be paid back? I thought after 10 years you had to start making principle and interest payments.
