I know it's highly unlikely that anyone with much common sense would do but I'm willing to bet there are some out there that have done it. 

The entry point for the equity investments are commonly £100 ($127) and there is one platform that lets investors start with £1.00 ($1.27).

You can take title to the other 50% as tenants in common.

Then, when they enroll in the local schools, I had to sign an affidavit certifying they are tenants, on the lease, and furthermore I'm responsible for fines, and reimburse the town for money spent on educating an illegal resident.

I like to tidy out the street appeal like mailboxes, sign, sensor lights and fencing. 

Its nice of you to help her out, but I've also watched Judge Judy enough to know how this could turn out. lol Obviously you can't sign a lease with her yet, so at this point, I would use the next month to determine if you'd even want her there for an extended period of time.

I take it there is no common place for the listing and sale of them.

I only need them to sign the paperwork removing them from the lease so I can add their replacements.
