I have to agree @Owen Dashner I had an insurance claim last year for roof and siding on a property, and because insurance doesn't pay for code upgrade on rentals, I had to cover ice and water shield, and some other things, on top of the steep deductible. By the time I got done, even though insurance was paying $15K, I was still out almost $4,000 from my own pocket. I didn't expect most of that expense.
I also once preventively replaced a furnace, and found out the AC was actually shot too. Another unexpected 3-grand.
I haven't personally priced a home warrantee, but my personal residence had one when we moved in. I tried to use it once, and the technician that was sent out knew less about my dishwasher than I did.
The point is, stuff comes up. You need to be prepared. If too many of these situations came up at the same time, you could go broke without some deep reserves.
