I would hope that the new location would appraise for all the additional expesnes involved in relocation of the home on a vacant lot and etc.
I would be a together an expense report determine if it is worth it, including city permits, who is the company moving the home? what is their reputation? Then determine if best to build a house exactly like the one you want to move.
I don't know much about moving a house in Texas, but every place else it's gets costly ...
If it's really flat ground, then it might "maybe" be an easy job for the movers, but it's still going to be a Martian landscape for you ...
On a moving structure it all depends on "any" elevation changes, a curb here and a curb there can change everything - 1 or 2 degrees can make all the difference in the world .. think about the last time you drove your car over a steep driveway, now imagine that being a house ..
Sometimes they'll try to pull the brick work off or pull the siding up to the fascia before the move, just to save what they can and have it reinstalled later ..
It easily changes or shifts the structure, interior framing moves, you have windows and doors that usually get skewed and things like counter tops easily get slanted from the walls, shower stalls have a tendency to distort, flooring turns into Mr. Gummy Bear, etc, etc -- and thats just the good news.
Unless it's a Century home or a city/county thing, most lenders won't loan but 50% of the property value and most insurance companies will only carry smaller blanket policies ...
Unless you're getting the dirt, the house and the "finished" restructuring cost at 20cts on the dollar -- then it's just not worth it .
I would question moving a 17 year old Jim Walter home as you apparently are.
As an aside, I live in Irving. The city has been working on road widening of several roadways for a number of years. In widening two main thoroughfares, the houses on one side of the road were demolished. They are now preparing to do a third and all of those homes were jacked up and moved. The homes that were moved were small homes built in the late 1950's that did not have a lot of market value at their current location. I'm not sure where they were moved, but I'm sure they are now someone's affordable home.
