Downpayment Percentage Pros & Cons

[Mike Sebastian]

Question from a novice.... 

Is there anything wrong with putting 5% down instead of 20-25% down if all other numbers work out? 

Reason for asking...I could buy two rental properties if I can put 5% down instead of 20% down, but only one if I need to put 20% down. I'm under the impression that more doors = more money, so a little less revenue from two units would be better in the long run than more revenue from one unit. 

I'm curious from more seasoned professionals if there are negative repercussions from doing this that I'm not seeing? Any and all feedback welcome, thanks in advance!
