My wife and I are coming up to the end of a two year lease on a property in Northern Virginia -- as we've been here, we've noticed that our kids have had persistent respiratory issues -- particularly our 10 month old son, who we took to the emergency room at 4 months old, with respiratory issues (we didn't think to check for mold at the time).As we've been in the house, the owner (who regularly cut out the property management company he had been working with), has mentioned that when he lived in the house, he had noticed 'pin hole leaks' in some of the pipes.. and when we pointed out a 1 inch diameter 'soft-spot' in the kitchen ceiling, he chalked it up to that.

I have PMs for my current properties so they are generally pretty passive already, but the DSTs would be totally passive, for better or for worse.The outfit I have been speaking with represents that they do greatly enhanced due diligence (e.g., multiple site visits on an anonymous basis), apply analytical stress testing to pro forma financials and avoid certain categories of properties altogether (Senior Housing, Oil & Gas, etc) to ensure that all underlying properties held by the respective DSTs are prudent investments for folks who are not experts in making risk assessments for these larger operations.
