That's before you get into the fact that MF, IMHO, is work/a job in comparison to my business model.All in ALL, I am seriously looking at NOTES.  

So what changed that allowed you to buy 33 properties in 3 years in comparison to the initial 3 rentals?

I bought them both in 2019, so it's not a fair comparison to today's market -- especially if you're comparing in Greenville where the $ amount of housing prices has jumped much more.  

ARV on my house is about $200K right now as a comparison.

My grandfather has lived in the home with my late grandmother for the past 30 years and is still currently living there but never held title to the home, so I'm not sure if that makes any difference in regards to how he will be taxed on the proceeds in comparison with his son whom has NOT lived in the home for 2 of the last 5 years.

You probably just need to wait unit your sales are a year plus old and they will stop looking at them for comparison. 

We do have a disadvantage that with duplexes we do not start noisy work before 10am and don't continue past about 8pm, as to not disturb the neighboring unit.It will get faster as you learn how to sequence things.We generally wait to show it until the big things are done.  

Regarding comparisons to other countries, I have worked with the Japanese market for over 8 years. 8% is definitely high yield.

But rarely do they bid in sequence with the public..

This is especially true if you have certain deductions that are higher than average.If everything looks fairly average in comparison to historical numbers then you are fine.
