These is where DSCR lending gets murky as there are some lenders that don't even care about this.

The “worst” appraisals I’ve seen (on a consistent basis) as to over valuation are on non operational health care facilities.  

Working on a few STR deals with savvy investor sellers and we are wrapping some really low interest rates so the DOS clause concern is very much alive… We have decided to go the land trust route w/ one of the properties to try to be as careful as possible.

I stayed mostly with Multifamily as other sectors like Student housing, Senior care, Hospitality and NNN have too much risk for me. 

Investing in properties tied to future area developments requires careful evaluation of project timelines and potential delays.

Any tips, insights, or things to watch out for?

Quote from @Gabriel Juarez: I’m turning 20, any tips for anything to do with real estate?

I would be careful not being honest with these companies as it can be huge penalties etc. if you are not using the information in a fashion they say you are going to be using it for. 

If the seller is unwilling to negotiate, walking away could be a wise choice to avoid unforeseen expenses and health risks.

However, please be careful if you go this route!
