Section 1014 criminalizes the act of making false statements to a financial institution.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

But wouldn't this be criminal not civil?

Coghill they are trying to take care of several things:1) Approval to access credit reportsA video tour of my home office (required by the credit repository to show security, so access to office & computers is limited to avoid data theft)Credit checks on me and my partner (required by the credit repository to make sure you are not criminals looking to steal others' data)Copies of the deeds for every property we own (required by the credit repository to confirm you aren't just self-serving)A copy of my partner’s home lease and utility bills (required by the credit repository to prove his legal address, so they can pursue him criminally if he steals data)Business phone bills (required by the credit repository to prove an actual business)2) Approval to use banking ACH system to accept tenant payments and pay ownersBusiness phone bills (required by banking industry to prove business legitimacy)A signed letter from the bank verifying our accounts (to prove legitimate business banking accounts.
