I'm considering using Zillows portable application, which makes a lot of sense for me, and for the tenants.  

I have portable AC in the garage I've used for tenants, that's a little more convenient than a window unit.

I know its not as full featured as the actual program but for your work computer it may be good enough (especially if you customize your tag structure and saved searches at home through the installed app).As for LastPass I would also recommend you try putting LastPass on a portable browser on a thumb drive.

My opinion is that the ship has already sailed.If you are thinking that the road warriors are going to burn your house down, gold coins are portable.

On the subject of generator switches this is the one we have been installing.http://www.homedepot.com/p/Generac-Prewired-30-Amp...But if you have a portable generator why bother with the cost & trouble installing a transfer switch, unless it's going to be a future selling point???

The reason I bought the number from tollfreenumbers.com is that it is portable anywhere.

(Every three years is a good time to upgrade though).With the desktop you can install it on your laptop and use it in the field so it is also portable that way. 

The neighbor next door also had a myriad of cars, vans and portable garages in his front yard that had me thinking it could be an issue when selling tilm came.
