They don't require employment verification, income or tax returns.

Sounds like this could possibly be a Schedule C activity so keep self employment tax in mind.

I am trying to transition in to full time realtor but unable to do so at the moment as financial demands require me to stay employed with my department 

For instance, sourcing cash flow deals is essentially nonexistent in affluent metro ATL markets with high employment, exceptional school systems, and attractive nearby amenities.

I would look for reviews on Zillow, Google Maps, Yelp, Experiance.com.To look up their license history you can use nmlsconsumeraccess.com, licensed and registered Loan Officers have to report a 10 year employment history.

I currently don't show income and just left my other place of employment.

Strong rental demand: With major employers like the Cleveland Clinic and University Hospitals, along with a growing arts and culture scene, Cleveland attracts a steady stream of renters.Revitalization efforts: Many areas of Cleveland are experiencing significant revitalization, which can lead to increased property values and appreciation potential.I can't comment on the Detroit market specifically, I have never been and have never done any research on it!

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 haven't had a full-time employment for a while but I have money saved up to buy a property or two.Is anyone here living abroad also or know anyone living abroad that is not physically buying properties in the USA but abroad?

You can fund it with funds in former employer plans and/or IRA accounts.
