You are being penny wise and pound foolish.

The only reason you should not enforce action is if its contrary to an applicable law or regulation...Here is another section from Seller Covenants:Seller agrees to honor requests for execution of endorsements of Mortgage Note from Seller to Buyer if made within thirty (30) days following the Transfer Date, after which Seller shall not be obligated to honor such requests.So if there was an issue with a prior document, after 30 days they can tell you to go pound sand - and based on court documents, this has happened. 

Prices on everything I own have gone up 2-3x and my cash flow went from ~$150/door to $500-$600.I still believe Detroit offers that opportunity today and is why I continue to pound the table on it.

This may be the worst case of being pennywise and pound foolish.

You were made aware of undesirable conditions and made immediate attempts to address the problem through a capitol improvement not just a simple repair.

I ended up paying 25K and they hauled out 120 thousand pounds of trash.

I hate to call people out but the gentleman above refused to provide adequate insurance coverage and insisted on pounding on my processor until she broke down and cried one late afternoon. 

Note my late fee is high enough to be a penalty, but it is not high enough to compensate me for effort to hunt down delinquent rent (my time is precious, I expect to be well compensated for my time especially if I am doing something as undesirable as collecting delinquent rents.  

I bet they are pounding on this guy hard to. 

But I think he meant you may have been being "penny wise and pound foolish".
