This slogan merely means you can put down ZERO and the Investment will be NEGATIVE but if you buy it without financing it, you will Cash Flow.You make the Investment Cash Flow.Also, Cash Flow can be a distraction from much bigger problems.Buying a Property that you cash flow in a DEPRECIATING Local Market is a set up for failure.Take Detroit during the decades before it went bankrupt.You may have bought a Cash Flowing property decades before, but the writing on the wall was that Detroit was going to depreciate when the Domestic Auto Industry was a decades long slow train wreck.Detroit, at that time, was 90% dependent on Domestic Auto.There are 2 rules that I follow:1) ALWAYS buy in Appreciating Markets with a horizon of at least 10 years2) You (notice, I said YOU) SHOULD Make the Investment at least break even if not some positive cash flowIf you are in an Appreciating Market, your Cash Flow will grow.For instance, I am in Brooklyn, NY and my first investment was in 1998.My rents went up over 350% (from $1k for a typical 2 Bedroom apt to $3.5k today) over the 26 years.Not only do I cash flow from the Rental Price Appreciation but soon my Mortgage will be paid off by the tenants.The Cash flow will be HUUUGE in about 2 years from now.Many Investors here seem to not understand that Appreciation is BOTH the Investment's Value and the Rental Price Appreciation.

I know that auto insurance premiums are more expensive as well here in Texas.

All my lenders as well have this same business account set up to auto draft their monthly payments.So, I simply have money coming in and going out of this account completely on auto pilot and separate from my checking or savings accounts. 

Do have plenty of cash reserves for repairs and emergencies Do have your properties with the same insurance company as your residential and auto for a bundle discount.

Quote from @Joe Hammel: @Leslie MonroyMetro Detroit (my rental portfolio is here)Purchase: $80k-$130kRent: $1200-$1500ROI: Double DigitCash flow: couple hundred/monthAppreciation: Double digit (for past 10 years, will gladly send data)Location: C, B- (suburbs and certain markets)We have over a dozen Fortune 500 companies just in Metro Detroit with huge Healthcare and Auto industries.

Even then some have already loosened up when the government finally started buying mortgages again.I also just spoke to a contracting business and an auto body shop and they are swamped, which I've heard from other business owners as well...again in my area.  

The two largest being hospitals and auto industries.

The price/rent/location ratios are hard to beat, and they work.Purchase: $80k-$130kRent: $1200-$1500ROI: Double DigitCash flow: couple hundred/monthAppreciation: Double digit (for past 10 years, will gladly send data)Location: C, B- (suburbs and certain markets)We have over a dozen Fortune 500 companies just in Metro Detroit with huge Healthcare and Auto industries.
