If we have reasonable assurance that the pipes are PVC, can we skip the sewer line scope? 

You can also counter this person with a lease instead of an easement. 

See, Hurricane Kartina, Maria, etc, etc,Bill, while there are cases of third party counter risk similar to "Equifax" getting breached, these are due to centralized points of failures and (generally) completely out of your hands. 

If you have a 3bed/2bath with 1,800 square feet, granite counters, tile floors, and attached 2-car garage, then you want to look for homes that have those same features and see what they are renting for.

Inherited tenants are usually a negative, however in that area leaving the duplex totally vacant makes it a target for thieves to come in and steal your pipes, furnace, and hot water tanks.

Getting the phone call that a pipe has broke or well pump is broken is definitely not the parts of landing that we love !

Within each MSA there are pockets of increases and decreases, which are counter to the overall growth or decline. 

Otherwise frozen pipes may happen.

Depends on property age but I almost always do a sewer scope, especially if the pipes are cast iron.

.* They dropped to $520K, we countered with $465K.* Our agents met and we learned that the lowest they'd go was $510 because of a HELOC* We offered $520K with $10K seller credit to be used for closing costs.
