Pay off Rentals or Invest in Equities

[Neil Masincupp]

Looking for some insight and any angles I may be missing.  I have 5 properties with financing.  I owe ~475K between them and the interest rates vary from 4.35 to 4.75%

I am trying to work out if I would be bettrer off pouring my extra cash (about 4K a month) into paying down my rental debt or putting that money in the market.  I am 41 and with ~25 years for the investments to grow, I beleive it could far exceed the interest payments given the realtively low rates.

Then again, I could have all my properties paid off in about 5 years...which would amazing.

Oh, I also contribute 15% of my income to my company 401K and that wouldnt change as well as my wife and I both having military pensions. 

What would you do?  Thanks!
