I moved the 2nd floor of a 1700 sf daylight duplex in Seattle in 1997 about 10 blocks. I had it for a dollar (on a handshake with the apt. developer till i got the Building permit) up to 5 days before the move after developer had scavenged out the daylight areas etc. when he told me he really needed 5k (lesson learned)!
Moving company was $17,500 and they were pros. Public works was about $1,500 for someone to drive the route the week before we moved it. The Cable and Telephone work was about $4k. Along with architectural, engineering, permits etc. I was in the 1,700 sf for about 50k in seattle. Not a bad deal, but your costs would be the same for 600 sf probably.
rule #1 move the biggest and nicest house you can fit down the road--preferrably 1 story.
We made good money on that property, build a 1,700 sf ground floor with another unit and full 3 car shop garage I ran my renovation business out of till 2006. We did a light remodel on the upstairs in addition to updating furnace/water heaters etc. Sold it all for $430k in may 2006 near top of seattle market. Always pissed me off that per sf we got terrible price compared to single family homes.
Watching that sucker go down hills and around corners was amazing at 3am sat. morning. House was 34' wide x 50' long and lot was 50' wide x 104' long. Seeing them swing it off a narrow city street into the lot was pretty amazing---met all the neighbors in their bath robes that morning.
We jacked it up 12 feet in the air on cribbing, poured some footings and chained that sucker down for 5 months as we were in the middle of another rehab--pretty amazing to get used to walking under that house after being terrified the first week!
best fun was watching folks heading down the street past what had been an empty lot for 20 years and see them catch a glance of the 2nd floor and hit the brakes wondering what the heck was going on :)
Best thing about a project like that is I can not imagine ever being overwhelmed by any renovation or new construction project again--okay maybe putting a house on a barge and hauling across Puget Sound or something to a waterfront lot--that is another story.
problem with most houses to be moved is developer seems to decide at last moment to try and reduce demo costs by "selling" it to someone to move. Trying to put together the building with permit and a site to put it on in short order is not easy, especially in developed areas. Pro movers usually have a "temp" storage yard they can relocate them to, Seattle wanted a "demo" bond in case we didnt follow through with everything--i.e. they held $5000 till COO so they could haul it off if I didnt finish it.
Movers Rule #2 Meet the demolition contractors as they always would prefer to move a building and save on the demolition costs and keep an eye out for major projects--highways, airports etc. that involve getting rid of lots of existing houses.
