Your idea on the social work aspect is right on.

Can her status and credit be of help as well?

Maybe they are bad communicators.Assuming you still want the place, I would do anything you want to reach out via the renal address or professional websites, but home addresses and personal social media is going too far.

These expenses can create a paper loss, which may offset other passive income or carry forward to future years.If you qualify for Real Estate Professional Status (REPS) or actively manage a Short-Term Rental (STR), the losses can be applied against your active W-2 or business income, reducing your overall tax liability.

Meetups, conferences, social media - connecting with as many people as makes sense and just discussing investing and what you do and if you found X would they be interested in investing with you.

It can be difficult to provide any predictive info (while scrambling in reaction to a worldwide pandemic), but at least a status update is always good.

Is there anyone they partner with here to put on US MLS, eBay, FB, all the social media sites, craigslist, land watch, land.com, etc.Who is your target buyer? 

Your profile mentions that you are an agent with rentals.You would want to see if you are able to claim real estate professional status.If you are able to claim real estate professional status, you can potentially offset the rental losses with your real estate agent income.Furthermore, TN does not have a state income tax allowing you to be more open with your options.Best of luck

Congrats, you're a rare find, enjoy your unicorn status! 

US population growth slows and fewer new households form, which is probably not great for RE investors; and 2. the Social Security trust fund runs out.
