Texas Multi Family-Loan Question

[Jason Burris]

I am considering the purchase of a 10 unit multifamily property in Texas for $375K.  The property consists of 5 duplexes.

My credit is fine and I have 20% to put down on the property. 

However, I have spoken to 2 lenders and am being told that I can only obtain a 15 year loan.  The reason for the 15 year term (or so I was told) was due to the type of loan (commercial). 

Have any of you obtained a commercial loan for over 15 years or is 15 years the industry standard?
