What makes you an expert? You didn't even know a house could be moved with the bricks in place.
I'm a contractor. I've built everything from room additions to 8000SF houses. I think I have a pretty good handle on what things cost.
It used to be you could move a house and the only things you had to do were the foundation, and utility hook ups. Not so (in my area) anymore. Plumbing and electrical must be brought up to code. That means ripping out the drywall or plaster to access it. You see, the inspector just won't take your word that everything is up to code. They have to see it! With the EPA RRP (lead paint) work rules now in effect those costs can be astronomical for houses built before '78. Let's not forget the hurricane clips to fasten the roof to the walls. Yep, you'll be tearing out the ceiling and upper wall drywall to put those on. Many houses built in the 50's and 60's used a diagonal 1X8 notched into the studs for sway prevention. Those aren't allowed under current code. You might get lucky and find an inspector that will let you use metal braces on the inside (after you tear off more drywall, and baseboard). If not, you'll be tearing off the brick and putting OSB sheathing on the walls. Let's not forget the new energy efficiency codes. Things like insulation and windows needing to be replaced. This is just the tip of the iceburg. There are many more things that may need to be addressed like straps on the garage door header. Steel plates in certain headers. C clips on plywood roof sheathing if the rafters are 24" OC.
You may not be required to do all those things in your area but in my area a moved house must meet current codes. In some cases that means gutting the house to the framing to make the needed upgrades. By the time you factor in the movers cost, permits, and the cost to bring the house up to code IN MY AREA it's cheaper to build new. In some cases a cash bond to cover potential road damage. The costs of moving and bringing a house up to code can often negate any value the structure may have.
A perfect example is the "free" house that ended up costing the town $276K. It's well under 1000SF. The 276 doesn't count the lot which was donated by a developer.
Obviously if houses are still being moved in your area they aren't requiring them to be brought to current code so there would be some value to the structure. It's certainly not that way here and other places as well.
