Loan Or Investment? What to do first?

Making investment to achieve financial goals can wait... I will better pay off my loan first!

So you are going pay off your 15 year loan in next 7 years. Fine. But make sure that you are not going to be "ASSET RICH, BUT CASH POOR" when you will need cash most. Let me explain. 

Say, after 7 years or within anytime next 10 years you also have a goal to achieve. At that time when you will need liquid money to spend, you may find yourself in an "ASSET RICH, BUT CASH POOR" situation i.e. though you will have a loan-free asset then (which you can't liquidate or sell in parts) but not enough cash to spend.

At any point in life you should never be in an "ASSET RICH, BUT CASH POOR" situation.
