Color me confused. Many unanswered questions:

Many of us do not have a property portal, we make payments via an ACH debit based on account and routing number provided by hardcopy paper form to our property management.

For those who make payments by the above method, the actual ACH debit date varies from month to month, by several days, thus making “within 5 days” impossible to predict. We give the management company the account and routing numbers, exactly when THEY choose to process the ACH debit is their choice.

Any fees involved with using “any other credit card”?

“Each month, pre-authorize” seems like a big step backwards, like writing a check every month, compared to all the automated procedures now in effect.

It’s possible Bilt is making things more difficult and complicated in an effort to decrease usage for rent, for which they lose money.

OTOH, if “earn both Bilt Points AND your card's rewards” (with no fees) turns out to be true, this might be a beneficial change.
