Or commercial printers rigging the paper cutter safety switch to free up one hand so they can work a bit faster.

Yes, they're old and single pane, but they're a huge selling point, if the weights are rehung (if they've broken).

It'll happen faster.

It might make it faster as it may be easier to line up.

How tall and wide the house is makes a difference and how much support it needs underneath to move in the first place.If you have to go across old bridges with weight limits, around a bunch of tight curves, low power lines and traffic lights that have to be lifted, street trees you have to work around etc.Distance and what time of day due to congestion house would need to be moved.10k to 30k sounds very light to me on moving costs.

Our Realtor confirms what we have suspected: units that use gas are appreciating faster than ones that use electricity.

Something along those lines, pour a relatively small rebar re-enforced footer, jack the floor to proper height then install a 4x  post. remove the jack and let your new post assembly support the weight. 

It is nice to hear the story, but the weight has to be on your due diligence.

I agree with @Dawn Brenengen I'd do it to harden the rental but as a realtor nicer kitchens sell or in this case rent the unit much faster hence shorter vacancy.  

It should be much faster and easier to get hard money than conventional.
