How to Make an offer for good investment

[Yakir Sheli]

Hello all,

I am a new investor and i have only 130k in cash for investment, I would like to buy and hold for cash flow every month, I am from Houston tx, base on prices I see online its look like I am too far from my goal of at least 9% cash on cash ROI, and only if I make an offer of 20-30k less then asking price, then Is a chance to be close to my target.

So i would like to know what's the best way to make an offer like that to reach my goal?

I am very new on investment properties. 

Thanks all.
