Aside from predicting the future, how can I change my process so that these letters come in a more timely fashion?

You're late... but you do look fashionable as advertised.

The way this is being reference in this post is not in the correct fashion.  

Betting its good old fashioned foundation damage.You will want to have not only an inspector take a look, but you might see if you can find a foundation company or structural engineer to check things out and get you a quote, because most inspectors will just tell you its a foundation issue and not provide any background on the scope.Foundation issues are common in Texas, every house you will come across will have issues to some extent.

In this scenario -- they will make 52 payments of $250 a year, or a total of $13,000 (one extra rent payment).But, the implication of doing that seems rather unethical to me, unless you are letting them know you up front you are penalizing them for paying rent in that fashion.  

There's also a section that lays out what the tow company has to do and in similar fashion if they don't they can be sued.Not saying this as something scary (because it's pretty easy to make sure you're operating correctly) rather it might waste more time if you have defend your case in small claims.

We investors are the experts in the Real Estate Community and seek to protect and enhance our reputation by keeping sellers informed throughout the entire process.In terms of a “subject to” transaction specifically, it is in our best interest as a growing real estate investor to make all mortgage payments and to do so in a timely fashion for multiple reasons:One of the first things we will likely do upon acquiring title to the property is make repairs and upgrades to the property.

in some fashion in order to put the expense onto the tenants completely.

I've also started clearing the house of all the artwork that you see in the current photos and have restaged my niece's room so that it looks more spacious and less personal.   

@Rick Pozos Sounds like the old fashioned way!
