Russ Mathes is a great KW realtor.

I personally don't know what you did exactly for your math.  

The larger your target audience the more stable your results. 10.000 addresses will yield you 10 deals for the cost of 60k.The numbers may be different, I made them up as an example, but that's the type of math that goes into it.

Due diligence, make your to get inspection, double check your math then have another investor check your math.Hopefully this helped and let me know if you have any other questions. 

So if I have a 3 unit cash flowing $100 per door, I am making $3600 annually on that building. I would need 10 of these buildings (30) units to make $36,000.I assume there are various tax incentives and such that may ...

. ($400 to $500 sounds like a lot of cash flow per month, make sure that your math on expenses is heavy or that you feel comfortable)I think its an easy choice to go with the duplex in AZ.

Mentors and guidanceIn the school online or in person you learn alot of laws, disclosures and the basic math.  

Definitely brush up on your basic math skills because there are a few of those questions but again, are simple.  

Feel free to msg me if you have any questions or want to look at the last deal and the process we went through.Oh, and Always double check your math...

If you have PMI - you can do the math to figure out if it's more beneficial to keep in 401k or pay down mortgage.
