Cash flow but not meeting 50% rule?

[Paul Quinn]

Hi All!

As my learning continues I have made it a habit to run numbers on houses just to get the practice. What I have run into a number of times is the potential rentals having a positive cash flow but not meeting the 50% rule. 

Is this a big deal? If its positive cash flow but not meeting that rule is it still worth buying? 

If not what should I look for or try and avoid? 

I'm having a hard time understanding this. Any and all information would be much appreciated! 

Thanks!
