taxes can more than double your monthly mortgage payment. 

That can double your taxes as well.As far as cash flow, you can expect around $200/ month.

I found that there were a lot of double negatives, ex.

We use our money as leverage to manage and shift risk so that we create double digit returns on an annual basis. 

You have to do double DD - on the asset and the business, but newer LLCs without any of the D's is a pretty safe bet.My last purchase was a $45k savings.

Ideally you would want to double or triple your money in rent compared to the mortgage payment along with your equity but that is not always possible in all markets.

It never hurts to double check. :)

This error ultimately had major implications because I would have looked at higher valued homes in different areas...this mistake also almost caused me to be denied the financing on the deal I found within the loan limit they set for me based on this incorrect DTI ratio.Long story short always double check the lenders calculations.Nonetheless I'm grateful that I'm able to move forward on this rental property.

As far as net income, I'd like to double my monthly outlays (8000 a month collection; I bought with 0 down at 4.15% for 20 yrs). 

I assumed so, but I just wanted to double check.
