No property is worth 2 years of your life and, once he counter sues, all of your sanity.

If someone promised me to return 24% on money borrowed and gave me a piece of paper I would make a counter offer to sell them a Brooklyn bridge.

Most US prescription drugs can be bought over the counter from the Pharmacist. 

Selfishly, being able to respond fast, mitigates damage to the property (frozen pipes, mold!)

Water penetration can also include roof failures or pipe bursts that allow water to leak into or damage your home.Either have the repaired area researched by your local expert and accept it.

Quote from @Will Reed: Im not sure how old my pipes are does Jetting only work with newer pipes I have herd ?  

My other counter argument to the opportunity cost is that your money is going from one investment to another. 

So white shaker cabinets and quartz countertops really don't get a premium, because a majority of the tenant base would rather save $200/mo and live with the oak cabinets and laminate counters.  

One year many pipes froze in our city, including one of our rentals and our personal residence. 

Someone just put in an offer. lol Now, I have to decide to hold or sell after a counter.
