Is it wise to put more Down payment for Positive Cash Flow ?

[Kunal Bhatia]

I am planning to buy a Condominium as a rental property with 25% down and lowest interest rate  - However when I crunch the $$ I see a negative cash flow of ~$100

I can compensate the cash flow it by putting extra 5 % (~30.5K) and getting a breakeven ( Slightly positive cash flow)

Does it make sense to put this extra money (5 % 30.5K) ? Or would it be wise to invest this money some place else and get a higher return and which will in turn compensate the negative cashflow ?
