This doesn’t occur often, but the deal is so good, just a few of these in the course of your real estate investing career will turbo charge your pathway to large net worth.Since examples can provide clarity, I’ll provide two examplesA number of years ago (7 years) I was approached about purchasing a note from a property owner who sold his retail center and carried back a $500k note, current principal $476,000.  

But this could also vary in your market, for example if inventory is so low then buyers may offer to pay your closing costs too. 

Lastly how do you decide on the rent per tenant as this model is so unique?

But there is SO much going on right now, and with so many variables changing in ways that are really all over the board, it's really hard to make the same assumptions that we've been able to make in the past 5-10 years. 

Real estate is so much fun.

This is so far my best real estate investment.

I'm comfortable with all of those, but I know that there is so much more than goes into your return than just those three main levers.Specifically, I'm getting hung up on 1) financing, 2) closing costs on both ends, and 3) holding costs

Similarities to self-management but there is so much more to learn especially if you want to grow your portfolio and add investors, or other landlords into the mix.

But the county is so large, it's hard to pin anything down.

Your post is so broad that almost any answer will address it.
