Then I dug a little deeper. 

The thing I like most about some folks who post is when they make me think and expand my thoughts into areas not delved into before. 

The point is, you either need to dig deeper, or just move on and find a more qualified applicant.

In many markets, the 1% rule has become impossible to find for the past couple of years (some of us old timers even remember the 2% rule, lol), so I would argue it's somewhat obsolete as a hard and fast rule (which is was never meant to be anyway).However: 1) This will change over time as the market cycles, and 2) It remains a useful metric that can be done quickly in your head to determine whether it's worth spending your time digging deeper into a property's financials.If a property is listed for $400k, and has a monthly rent roll of $3,500 (.875%, still not 1%, but close), it's probably worth taking a closer look.

Is there a tool available to weed out the poor leads from those that require a deeper analysis?

I have yet to really delve into the networking aspect.  

There has already been a ton of work that has gone into getting us to this point that i can get into deeper in another post.

@Ned Carey Thank you Ned for the feed back also thank you for guiding me where to go so I can dive deeper in this. really appreciate it. 

A $45K house that rents for $850 will generate some cash flow.That said, you have to dig a little deeper.

However, it seems to me that we have a problem deeper than the fact that too many Americans rely on the government.
