Maybe bringing in a portable stage, and portable bar for private events and parties.

Also, I'm in the same situation with the portable alarm that I use at both my house and the rentals.

The sauna tubes that it was built with have been upheaved due to permafrost (#alaskaproblems) and this has caused significant drywall damage to that unit only (for those who don't have the luxury of knowing what permafrost is here you go: http://www.cchrc.org/permafrost).

My team and I are trying do market research for a portable dishwasher.

You can always get a gym membership for like $30 a month and enjoy the pool, hot tub, sauna for a percentage of the costs of building your own.

I am not tied down to one particular location, so I am wondering if there is a particular state that makes it the easiest to transact in other states based on reciprocity or portability.

Or gee, I bet if I tripped and fell on top of that portable table saw on the floor I might not see another day.

Houston seems like a great place to invest, and as others said, the low prices of oil don't seem sustainable (at least until oil is really washed out of the feasible portable fuel market) in the coming 5-10 years. 

I was thinking about maybe just buying a portable unit(5,000 btu's) as a temporary fix for $200-$300 which would be a lot cheaper than repairing/getting a new AC.Advice??

From what I know Central AC is pricey, portable units only work for small rooms and the window units won't fit in my smaller side sliding windows.
