I discovered my current mortgage is behind secondary to an increased in December; I am using automatic payments and didn't notice the partial payment notification.

Additionally I would have countered trying to make my offer more attractive other ways - i.) waive financing contingency, ii.) show poof of funds, iii.) increase earnest money, iv.) offer to pay any short in appraisal up to a certain amount (say 1% of offer price), v.) provide a low-ball offer but with an escalation clause (you'll automatically pay X amount higher than highest bidder), vii.) say you'll pay for home as is without expecting them to fix home. 

Mortgage insurance falls off of a conventional loan at 80% LTV if you request it and 78% LTV automatically. 

Then my credit union (BECU) whom I bank with but don't hold the mortgage with offered me one with no automatic withdrawal requirements.

The appointment is automatically added to our calendar.

We discovered with many other landlords or rental agencies that a voucher meant automatic approval.

High-cost option, purchase a software that syncs your STR calendar with the software, input text/email of cleaners, and this will automatically notify cleaners for bookings with check-ins and check-outs, and if they are self-sufficient enough, they will go when needed. 

I just attended a QBO product update webinar last week and found out that they will soon roll out a new feature for "automatic late fee" (right now it's still in beta and available only to few users).

Quote from @Wayne Brooks: @Emilie Adamovic1) the vast majority of these get caught up/paid off just before the auction2) here, tax auctions are very competitive and sell for near market value, so the owner gets the excess proceeds.The first part is what I had assumed is the case, people will figure out how to pay the taxes before the auction. when the house sells for close to market value, does the excess in the sale automatically go to the owner or does the owner need to know about the auction and then claim it?  

I guess I just dislike the standard automatic invest in your back yard reply.
