We are 95% finished fully rehabbing (foundation, roof, plumbing, electrical, etc) an investment SFR bought with cash and intend to cash out refinance after the 6 months required (so we don't have to do delayed financing). 

It seems like it is a big space, but I doubt you want to move any plumbing? 

Other than that, there are certain discounts that some companies may offer if you have a security system, sprinkler system, updated plumbing and electrical, ect.

Plumbing problems make me crazy!

All utilities are off, so there may be hidden costs of AC/Heating and Plumbing issues, although it doesn't look like it.  

They are so good and possibly I'm use to NY prices but his prices are damn good and knows everything from roofing, electric, plumbing, floors, etc, name it he and his boys can do it and know exactly how to do it.

Give a call to a local plumbing contractor or two and they should be able to help point you in the right direction.

It's $40 per month, and if you raise your rent by that amount, essentially the tenant is paying for the warranty.If anything needs repair, with the $75 service fee, you still win.Without warranty, Plumbing and hvac repairs usually cost $160-$$arm and $$leg.In my own 20-year-old home, I do not have Home warranty, and recently had to pay out of pocket for a copper water supply line leak, where they had to cut open the wall. $800.

The dreaded words the plumbing does not hold pressure scares off most of the owner occupant buyers. 

All new electrical, plumbing, Sheetrock, floors, roof, appliances, counters, cabinets and basically everything you can think of, so I basically have 0 monthly maintenance on it.
