Tesla semi will go 500 miles on a charge.. and will have Super Duper chargers that will give a full charge in 30 minutes. so why they are loading and unloading wa la its charged and ready to go.Also they are FAST and unlike diesel trucks who strain to get to 45 MPH up a 5% grade TEsla will do 60 MPH  and oh to 60 with 80,000 pds in 20 seconds compared to over a minute for diesel.. batteries are good for over a million miles.at least out here in the west were we have a lot of mtn grades on our hwys your shipping time drops you save HUGE money on fuel.. and there is no oil changes .. and very little maintenance.. and brakes will last the life of the truck as the regenerative breaking will stop the rig.. 

This 3 bed 2 bath got a complete make over; new kitchen with stainless steel appliances, new double pane windows, tile throughout, air ducts replaced and ceiling raised, updated plumbing in bathrooms, kitchen and laundry, luxurious and spacious bathrooms, and so much more to list!

I hear the Colorado river is pretty strained.

So far it's not a strain on my neck.  

However, my wife and I believe we can increase rents significantly by making improvements to the property such as double pane windows, security doors, better insulation, etc.

An ADU just seemed like a cleaner, separate way of doing this... which I still think it is but if budget is strained, I could potentially do what you're saying.  

In terms of energy efficiency, we are installing triple pane Intus windows with a U-factor averaging 0.18.  

An obligation of this magnitude can exert a remarkable strain on the economy by reduced spending power of the student-borrowers, and by exerting a deleterious effect on the credit worthiness of the United States.

Other little stuff, like the bathroom and the lock on the door are easy tiny issues, and the electrical panel is a maybe, only if my electrician thought it was necessary.$3500 credit to me sounds like more than enough money, assuming further investigation didn't reveal much else, obviously I'm not privy to the details of the property.

flat portions of the roof, aluminum wiring, Federal Pacific Electrical Service panels (if they are part of the NJ class action), corroded cast iron DWV pipes, pink or lime green bathroom tile, aluminum single pane windows.
