Actually GFI outlets will not work without a ground. GFIC's is the complete circuit with the GFI being the receptacle. Is your electrician advising of replacing all wiring for those circuits? Running a separate ground is not to code. Also have you checked to see if the boxes are metal? The boxes in that age home are grounded on the side or rear. So you will not see a separate ground wire in the outlet box. Get a second electrician to take a look. The code is "If you don't upgrade, adapt or add to the electrical circuits then the circuits are withstanding" . Meaning that you should not be forced to upgrade to GFIC'S. If you get a FHA buyer then play dumb and give them a $150 repair credit to change the bathroom and kitchen receptacles to the GFI type.
This is very bad advice and misinformation. Code varies a lot depending on the "authority having jurisdiction." What you are saying might apply in Vegas, but it doesn't jive at all with the Seattle area. Plus I very much dislike any sentence that includes "just play dumb."

Ok...I'm a licensed electrical contractor... Allow me to explain how a GFCI works with the hopes you will use this information to make the best decision for you. A GFCI works based on the principle that if "something" causes an imbalance in current between the hot and the neutral(grounded conductor), the GFCI trips instantaneously. Now that "something" usually refers to water, however could be anything, an overheated motor, faulty compressor, a fork, etc. So, whether you choose to install GFCI's at every location, or GFCI circuit breakers, the level of protection is the same. People are safe, electronics are somewhat safe.
I agree with this gentleman.
I completely disagree about buyers not caring about the ground. I was frequently called to fix this issue from seller's agents or contractors.
Your best bet is going to be finding a ground behind the receptacle connected to a metal box. Just swap out all the 2 prong for 3 prong and connect the ground.
In the real world this probably isn't the case. GFCI breakers will not solve your problem. When was the house built? Is it the original wiring? Assuming you don't have a ground, I see 2 options: You can rewire the whole place. Or, you can replace all the outlets with GFCI receptacles. You are flipping a house that a family will be living in, it needs to be as safe as possible, which is modern code. The cost to replace all the outlets with a $25 dollar unit might be significant. It will probably be worth just re-wiring by the time it's done.
All of my experience has been in the Seattle area. You really should do what the local authority says. Figure out who's in charge of inspections, and ask them.
