The risk of a long term loan is the non-payment of the loan and the inflation rate. It is a severe possibility and you could not pay back for such a long period. And also if the inflation is high then you have to pay more for it.
Long term loans such as Home Equity Loans and Lines of Credit are sometimes linked to changing interest rates-but worse than that, most of what you will pay in the beginning may be interest. Anotherwords-You still owe a bunch of what you originally borrowed, unless, of course, you add more money to your montly payment. The best loan I've found is a fixed short term 'simple interest' loan which usually doesn't require so much paper work, or risk on the banks' part. If you must go with a long term it may be advantageous to temporarily deduct the interest from your Income Tax ...assuming what you save will be more than using the standard deduction. Look around at a library or online for a copy of the Consumer Reports Money Advisor. It's a monthly publication about 10 pages long. I'm not sure but it's possible Suze Orman may have some hints on her website...check it out. Don't quote me but I believe if you include an extra 'principal' payment along with each monthly payment, you will half the life of a long term loan (and save a ton of money in the process).
For the lender, one sad ending may be that the payee has met their end...that's were the risk exists! A Formal Bankruptcy occurs and the mortgaged little one still is not out from under the burden of the interest rate & has no monies to repay. Under the reformulated USA's laws, the debt will be there, hanging over your head forever...just the same as many of America's first settler...as indenture servants but till you die!
