Smaller Downpayment or Lower Interest Rate

[Nate J.]

Hey All, I'm trying to get some feedback on a financing question.  I will be seeking financing for a $150k loan as an investor with a standard lending institution.  I can either do a 20% down payment and obtain a 4.625% interest rate or a 25% down payment and get a 4.125% rate.  On the 25% deal, my cash on cash return will be 21.24% ..... on the 20% deal my cash on cash return will be 23.62%. 

My thinking is that the lower down payment would leave me  $7600 cash to invest, while returning my cash on cash faster.  Yes I get a slightly higher cash flow with the lower interest rate and a cheaper overall deal but ....

What would be your deciding factors when making this choice.
