@Jeff Quinlan I have a flat roof on a building in Aberdeen WA.

This home is one of four units in a property I recently purchased in Aberdeen, Washington.

Also be aware that the cost of moving a house is affected by many factors including type (single story versus 2-story), size, location (you can't move a house under a 13 ft underpass), overhead utilities (mover usually has to pay for temporary hook-ups), traffic (house moving only travel at very low speeds (5 mph is fast for them) so traffic gets tied up, coordination with city, state and county officials, paying for escorts (many times police).You might wish to purview the following:http://realestate.msn.com/article.aspx?

He could indeed sue you for costs incurred by him for your inability to hold up your end of the bargin, such as movers, a storage unit, a hotel until they find a new place to live, etc... 

@Ben Leybovich is a needle mover.  

Her house did not have a functioning septic system and was a short sale, so quite a few issues that made it a 'slow mover' for most people.She worked with a local community bank to do a short term 3/1 ARM 'In House' loan, which as soon as she got the work done she refinanced into fixed rate long term financing. 

You have possession of property, so you could pay someone to immediate put all items in a storage locker, Then after expiration of the waiting period, dispose of the items from the storage locker, then deduct costs for initial movers, storage fee, and labor you hire 2nd time to dispose items from storage after.

Annual $25 for a business license, $5 each additional unit + $50 city code inspector every 3 years in Aberdeen, WA. 

Working towards my first RE deal and this seems like a great way to increase my earning power while learning how to valuate properties and potentially build relationships with the movers and shakers.
