Pay down mortgage or save the cash?

[Ashley Lynn]

I am about to purchase my second property with almost 100% financing & equity from my first property. Goal is to buy a third a year or two after that. Question is do I use any extra money I have to pay down the mortgage faster? Or save the money for a downpayment on property #3? I know 100% financing isn’t ideal. Especially in this market. Thoughts are appreciated!
