It works well for us because we have built reliable teams (consisting of a professional general contractor, a property manager, an appraiser, and an inspector) in our markets.

@Kyle Smith I am a licensed Home inspector and Realtor in NH.

If the buyer's inspector comes in and says the 100 amp service is not adequate, what's the course of action?

Do they arrange inspection of the property or they will let you look for your own property inspector?

Where the inspector has to warranty the inspected system for 3 years. 

Any recommendations for a reputable home inspector in Memphis?

We would meet the inspector and based on the inspection, photographic documentation and proforma, we would proceed with an offer. 

The inspector said the crawl space under the house is very tight (approximately a foot maybe a little more).

You will only be advised to "seek professional advice".I am an accredited inspector, and I can tell you 100% that most inspectors don't know anything outside of what they learned in a class about construction.

Inspector said related to house not having gutters, so rain puts pressure.
