<prompt> Human: Facts:Purchased condo in 2009 for 127,500Initial loan amount for mortgage was 102,000 at 5.5 interestCurrently have 88,480.30 remaining on loan balanceThe current value of the condo is sitting at around 95-100kI would like to try to refinance to take advantage of lower interest rates, and so I am currently paying extra towards my mortgage each month. I cannot find a place to refinance since the value of the condo dropped so much since I purchased. Is it wise to continue to pay extra each month in the hopes that eventually I hit the 20 threshold to refinance, or should I stop paying extra on the mortgage and invest the extra money?  <response>: Along with the benefit of gaining equity in your condo, getting a gauranteed 5.5 return on your money is also quite good. I would feel pretty good about investing my money into a condo instead of elsewhere, as long as you dont need the cash elsewhere.
