You'll spend some time watching the videos and in return you will get some free education. 

It's likely a scam anytime they sound like AI or the grammar is weird or they use the word "kindly", if they ask for you to respond to them off-platform, if they say their employer will pay for it, if they ask if the dates they've specified are still open (when they can clearly see they are open on your calendar), if they ask for a video of your property (they probably want to set up a duplicate listing with your photos and video and scam others out of money), or if they want a long term booking and they have just joined the platform and have no reviews (could have been evicted from somewhere else, and hope a newbie will let them in with no background check, they'll end up not paying or credit card is bad).  

I assumed a total loan of around $90k with a monthly payment of just under $1,600 using a random SF property in Indy with a similar asking price.

We are looking to eventually relocate to the States"--that's great, a lot of people want to invest remotely in a totally random market and never go to it.  

I try sending a video or doing a live video walk-through with them so they can get a better idea of the layout, condition, neighborhood, etc.2.

I have some YouTube videos that may help with some of your questions and always happy to have a call to dive a little deeper. 1. which development(s) tends to be the best for ROI/have the best occupancy rates? 

He knows his stuff and is really good at making IG videos: his brand is a very clever mix of being super humble, telling everyone profits are less than you think and then flashing some fat $$ he made by selling to his investors.

Yeah, I saw that dozer video too, that's a big one!
