Am I allowed to use a private investigator to do a background check on potential tenants, WITHOUT letting the potential tenant know?

There is no real estate involved; they are on a lease.My bank is currently looking at how much they can give us for a cash out refi of our rental condos, but we are trying to investigate all options.Thanks for any advice. 

I'm starting to investigate more creative financing options to scale faster in 2025 - 2030.

I was actually on a team dispatched to investigate the Surfside Condo collapse until the clean up process basically rendered our investigation moot. 

I was told if I could show a professional license such as a broker license I might get approved but the best option would be a Private Investigators license, otherwise, they didn't see any other path to approval for me or my company.

That they are investigating. 

I have applied, scheduled to have the lead investigation for hazards soon. 

If you are looking for cash buyers who don't do any investigations then I'm not your guy. 

Are they going to flag it as a statistical abnormality and send investigators after you?

I've casually investigated this before, but haven't spent to much time on it.
