General downfalls of a TIC is that one person can bequest/will/sell their portion to someone else without the other person's consent.

You can’t call a consumer with automated technology, unless you have express written consent.

That may be true, but I usually don't consent anyway. 

As used in this Section 18, “Interest in the Property” means any legal or beneficial interest in the Property, including, but not limited to, those beneficial interests transferred in a bond for deed, contract for deed, installment sales contract or escrow agreement, the intent of which is the transfer of title by Borrower at a future date to a purchaser.If all or any part of the Property or any Interest in the Property is sold or transferred (or if Borrower is not a natural person and a beneficial interest in Borrower is sold or transferred) without Lender’s prior written consent, Lender may require immediate payment in full of all sums secured by this Security Instrument.

@Eric Worral If I create a RentPrep account and have the potential tenants log in themselves to enter their information, does that cancel the need for written consent for running a credit/background check?

Ask for another check immediately, if they claim it has been cashed, verify with a third party by calling the financial institution and asking questions about the check with the consent and help of your tenant. then move over to a more modern way of collecting rent.

You can read the actual statute for yourself or read the pertinent paragraphs below:(d) The landlord shall, within 45 days after the date that the tenant vacates the dwelling unit or within 7 days after the date that the tenant provides notice of termination of the rental agreement pursuant to Section 5-12-110(g), return to the tenant the security deposit or any balance thereof and the required interest thereon; provided, however, that the landlord may deduct from such security deposit or interest due thereon for the following:(1) any unpaid rent which has not been validly withheld or deducted pursuant to state or federal law or local ordinance; and(2) a reasonable amount necessary to repair any damage caused to the premises by the tenant or any person under the tenant’s control or on the premises with the tenant’s consent, reasonable wear and tear excluded.

I have a tenant from NYC and she's mentioned that renting is just what she's used to.It does seem like she's offering a good deal to alleviate your fears, but like others have mentioned dealing with the nonsense the government imposes between such an agreement between two consenting adults might make it a PITA, and if she's a skillful mooch in an anti-landlord state she may be trying to bait you into a problem.

I have consent in a text of our agreement for these days.

In addition Tenant agrees to pay any re-rental costs incurred bythe Lessor including but not limited to utility charges, advertising costs, statutory costs and a re-lease fee as follows: one month's rent.b) If this is a MONTH-TO-MONTH agreement as defined in 1 above, Lessor or Tenant may terminate this Agreementupon writtennotice received by the other at least 20 days prior to the day on which rent is due.c) A “HOLDOVER” occurs when Tenant fails to move out of the property by the date in the Tenant’s move out notice orLessor’snotice to vacate, or at the end of thelease term, without the prior written consent of the Lessor.
