They are spaced nicely for privacy which gives my tenants the fill of this being home, not just a rental.

I was recently approached by a huge national lender (withholding name for privacy reasons.) to see f I would like to work with the leads that they provide me. 

Something that's easy to manage, and almost comparable to renting out a room in a single family but with more privacy.

You can do an NDA or you can ask them not to share, but this generally isn't a huge concern and if the concern revolves more around privacy I'd spend money on an LLC or DBA and a PO Box before I'd spend money on an NDA.

It feels like a serious violation of my privacy.

The wife (or husband) wants SFH for the space and privacy. 

If you get yourself, say, a duplex, you get the privacy of your own residence while someone else pays either all of or most of the associated costs.

To give a few examples from my market, more people are interested in SFHs with fenced yards so they have privacy and don't have to deal with a neighbor one wall over making racket at 2 am. 

And also I'm surprised your BC group has a tenant registry, it's commonly accepted here that they're illegal because of privacy laws.  

Blinds are for privacy and to keep the Mickey mouse sheets out!
