15 or 20 year refi?

[Mark Ossman]

I'm about to refinance my investment property under the HARP program and was wondering if I should go with a 15 or 20 year fixed. APRs for both are attractive and the 15 yr. would be about $180 more per month and I would save about $20k on interest over the loan period. In general, does it make more sense to go with the shorter term considering the savings on interest or is $20k over 15 years not enough to matter? Are there other things I should consider besides the APR and interest before making my decision?
