Of course, have a plan to pay it back but it's a great way to utilize money that is basically tied up, and losing value since in a couple years it won't be worth what it is today.  

Therefore because of the low inventory there is it 0% chance that there's going to be a crash so if you are going to keep this mindset I would highly suggest you do research on what's really going on with regards to inventory because you're going to lose out big time.

Even going through the process of having all my deposits coming in a the beginning of the month and paying bills out of the AIO at the end of the month, wouldn't you be losing lots of money versus a 15 or 30 year fixed mortgage? 

I'm not sure what to do in this situation, whether to drop the deal and lose my earnest money or try to find another lender.

So every year you do not compensate by raising rents, you are losing money.

There's always going to be win/lose minded people who struggle to figure out what it really means to have that win/win mindset.

Also, if I place bad tenants frequently, I can count on being fired, so what sense does that make to ruin my reputation and lose other business for half or 1 months rent commission?

If you get a bad tenant you don't want that to cause you to lose your house!

They could get a risk free return by investing in T-bills, so the delta between that RFR and what you're offering needs to be rewarding enough for them to pursue it.As for the 2nd part of your question, that really is a mystery :)The low interest rate environment always leads to these folks misleading people and mismatching deal operations, and sometimes even defaulting on the property and losing it altogether.Probably because a bunch of these syndicators want to be cool Instagram/TikTok influencers and throw up their arms and talk about how many doors they own, but what do I know lol. 

I have no idea if you can use this approach as a Foreign National but there's nothing to lose in having the discussion.
