So if every year I would buy an assumable rate property and live in it for a year then rent it out and repeat this.

So if a client is at the 37% rate a $10,000 study would only really cost $6,300, and that doesn't even include the state tax deduction if applicable. 

What are the vacancy rates in the area according to AirDNA?

I kept meaning to buy for a few years, but I’ve been simply overloaded with a startup.My current country prevents me from purchasing property (non-citizen), and doesn’t offer fixed rate mortgages - the floating rate is high rate at 7%, and has been about this the last 20 years.

Purchase Price: $585k with a $100k down payment on a 2.7% interest rate. 

They are most likely  going to be the better borrowers, with greater success rates on execution along with likely having access to better deal flow and thus the better collateral.

(I will let you draw your own conclusions about my parents' finances given that they gave me a $150k down payment without much of a conversation about it.)At the end of the day, I lost money on the property from owning and operating it, and my parents made a modest profit from the sale.

But from those conversations I have learned it is block by block. 

Beyond the common terms of the loan: interest rate, overall term, down payment; commercial loans are almost always full recourse to the borrower.
