I would prefer just to leave the grass and start saving and regrouping for my next investment but unsure on what to do.

You just need one of them to not fill out the application completely, or to put wrong address info (this is one that most tenants actually do - they don't give you all of their prior addresses that you've asked for), they won't have verifiable income for the last year, or references from non-relatives (no references allowed by relatives they lived with), one of them at least, won't have good credit.And then, when they try and regroup or find another roommate, you can just say, I am sorry, but I don't rent to groups of people who are wishy washy about who will be living in the house, and keep changing their minds.So, IF you have to allow them to rent as a "unit," just start processing their separate applications thoroughly. 

Example: This past year, I've been working with the RE group in a big company.

My goal is to create a comfortable environment were your true self-comes out... not the person that feels they have to impress everyone.I have some general ideas about its direction:- Purely Networking and sharing ideas, not a space to pitch at people like some other events- Relaxed environment- Free meetings- Some type of media integration- The goal is to connect good, high-quality people- Meet once a month for several hours- The group would not act as a business as some other RE groups or meetups (no memberships, paid classes, etc)If this is something you would be interested in and feel that there is a need for this please let me know and give me feedback!

What happens in real life is that all investors cash out and then some of them may regroup for another investment opportunity.

Sell the rental , regroup , and never get in that high on credit cards again .

If you bobble a little hear and there you have time to regroup and recover.If you have time consider spending 30 minutes for 30 consecutive days on Bigger Pockets.

Simple, just go to the local RE group and connect with GC'S , other investors and PM co's 

Talk to a local closing company and tell them what you are planning and they can tell you how it works.Not sure about any RE groups in Enterprise.Let me know if you find a good deal in the Montgomery area, I pay cash for a flip project and I will be needing one in 60 days or so to 1031 my current flip.

How do you recover and regroup from a bad deal or a deal that went wrong?
