However, I'm still struggling with the concept of using hard money for rental properties you wan to keep for the long term.

On this same concept, I don't typically buy single family rentals unless my gross rent is less than 1.5% of the purchase & rehab amount. 

I would like understand this concept correctly.If I purchase Property A-Duplex for 70K and it is worth 100K and I put 10K down, I will then have 40K in equity in the property upon purchase. 

Small houses  with little light I use - sherwin Williams Icicle flat- linen white trim (below)..Have also used Behr basic Taupe with Antique White trim-- its a nice pop against dark wood floors.  

It is all just reading material so it is basically like you are sitting in front of a computer reading a text book then taking exams throughout the material.

Basically - if you are doing seller financing you want to use a loan originator who is properly credentialed to put the loan together rather than doing it yourself.  

You have 4 basic tools:1.

To be honest, I'm not familiar with the concepts that you mentioned above but I am interested.  

Why would they want to partner with me if we are basically doing the same thing? 

This is basic economics, finance and appraisal methodology.
