My wife told them they can move in, but i told her to tell them that even though they are friends, that I run this as a business, and will not give them any special treatment becuase they are her friends.

Otherwise, you need short term financing through an alternative financing source.  

I don't see how these are alternatives strategies for one another. 

Alternatively, I can't help but be a little hopeful that 3 families saved their homes. :)  I did quite a bit of research on each property and any one of them would have been a good BRRRR according to the "numbers."

There's many alternatives to start growing your portfolio.

I think the lease states I have to give them 24hr notice if I want to enter.5.) what alternatives are available for hardwood floors, for middle/high end rental property?

For instance with dogs I insisted they have monthly flea treatment as well as heartworm treatment.

You cannot treat different partners in a syndication differently without economic substance, just because it gives favorable tax treatment to some partners.It might be possible to structure things this way if different partners have different level of participation and different risks - which is case by case and high-end as far as tax planning goes.

Or alternatively, is there a way to have a reduced price if there are more than 2 adults in one application? 

Maybe, but there is a risk versus reward trade off and you’d be taking on the unknown risk when the alternative is a guaranteed reward.
