Yes, I am staying patient, still feels like drinking from a fire hose.

I would buy a $600 power washer and 300 feet of water hose.  

We had 2 homes that had issues with outside hose bibs. 

I think most crashpad owners just bite the bullet and hire a cleaning crew to come in once a week or so and hose down the walls to keep the filth in check.

.- several electric space heaters- mobile AC units- a couple carpet blower fans- a couple high capacity dehumidifiers- an electric submersible pump with hose in a bin ready to go- a puddle sucker pump- a shop vac to suck up water and a big squeegeeI have not yet had the need for a generator.

As a landlord obligation, cover outside hose bibs with styrofoam insulators.

@Andrew Kutscher Your friend is getting hosed.

=======There is no school that teaches this that I know of--contracting is ("Skilled" Manual Labor) for a profit.Some trades have apprenticeships, but that can take years of hard labor, in the hot sun, or in the cold snow.I'm not saying you can't do it, I'm saying to get experience in so many trades will take until you retire.If you want to be a GC you need to know how to bid and how to supervise subs (meaning getting the quality work done that you expect them to do).The reason I gave you some questions to ask yourself is contractors I've met seem to have (an interest) in this type of stuff that goes beyond just working with it, like Nascar Fan has interest in all of the Nascar details. the engine, the pistons the drivers weight, new go fast gadgets and etc...But if it's what you want to do--I say go for it--but go for it with your eyes open.Here is a video about pneumatic framing nail guns (they weigh about 8 lbs loaded + a bulky long rubber air hose)Is this something you would want to hold 8 hours a day?

I wrote a blog post discussing it and the numbers - Hose Hack or Hell Hack. it save us ~2..5k a month, plus allows my wife and I to still work.

A garden hose on full blast is 6gpm, 360 gph.
