New to Investing and Rentals - need advice

[Josh Midkiff]

I am a 39 year old software engineer, looking to get into rentals and whatnot.  I had a 3 single family home package sent over by my agent.  Total of $180,000, all 3 have tenants currently and rent for 700-800 per month.  I currently have $15k to start with, so not enough capital to purchase the entire package deal.  I have run the numbers on each on separately, and the cash on cash return is 20%~30%, if I had the 20% down for each one.  I figured getting 3 doors that cash flow off the bat is a good start.  I need some guidance on how to make this work.  What are my options?  Keep in mind, I am very new to this.  So, if this is a bad idea to begin with, just say so lol.

Any help is greatly appreciated.
