It will literally be possible for the landlords to know which of their tenants are insolvent before many of those tenants know! (An insolvent tenant that has not yet filed for bankruptcy can usually be summarily evicted under contract law, but previously, collecting such evidence of insolvency was time consuming and not cost effective, giving the tenant time to pull out of their tailspin before missing rent payments and filing a bankruptcy petition.)
In practical terms, it means that people just starting out (or starting again) are going to be heavily marginalized and wind up on the streets, group homes, etc. after one of life's many possible adverse events leads to the suspension of their income and depletion of their reserve funds (layoff; family medical issue; automobile accident, etc.) https://youtu.be/56u6g0POvo0
