This is how he explained it to me.

After I explained that after a 6% commission, cap gains on the "investment property, income tax (to be reported by the son) that it would be more economical for them to sell it to me for $150K with no realtor.

I’m not sure where my question fits in or precisely how to explain it but I’m trying to decide if I want to refinance with a different local credit union for a slightly better rate / term. 

Best bet is to meet with someone face-to-face to explain your situation and see what they would be willing to do for you, I'd recommend researching and setting up meetings with a variety as it may take some time to find the right one.

He's extremely helpful and is happy to spend the time explaining and answering all your questions.

Can you explain the NNN lease arrangement a little more?

Really looking for a source or maybe course that will explain off market lead generation, seller finance structuring and contract setup etc. 

Do: go to a lot of networking events, work/study/learn every single day, commit to the processDon't: Spend a bunch of money on coaching right away, get shiny object syndrome, think 'get rich quick' is realisticGo to meetup.com and find real estate networking events close to you. 

Would the objective of that be to get them to give me his personal number?

Just have a better general understanding of what I'm looking at so that I can explain the numbers to someone else.
