IF Tesla did get cheap enough then Apple or Google will come in and buy them so you won't be left with a car with no company to support/service it.One other food for thought, IF Tesla can get autonomous cars on the road in the near future your car would go from a depreciating liability to an income generating asset (although I'd never make a decision on that rosey outcome) if you're willing to let your car be part of the tesla Robotaxi fleet when you're not using it.

for you as the landlord...Maybe a nice benefit that you can use to raise the rent, but if a renter has a choice between two units that are equal in every way, but one is $150 more a month because of the solar panels, I bet they'll go for the less expensive property...They'll think they're comparing apples to apples, when in fact you're offering apple plus a little extra.....I know that in theory they'll save more on utilities, but it's a variable saving and it might not translate well when they are looking at rent only.This also might have to raise your percentage when considering cap ex when trying to determine if its a good deal or not.

Like in the 90''s waiting to see if Apple stock was a good purchase.

Coming from Silicon Valley used to look at dual income high tech professionals your principle mortgage is slightly higher than borrowers from Apple, Google or Facebook at 300-400K per year.

VTSAX for the commanding win, this time.It's as "apples to oranges" as it gets!

There are Mechanical Engineers at Apple making over $500K a year.

Obviously that's not what you are talking about it's apples and oranges.

Companies like Apple and amazon are filthy rich because they have a ridiculous amount of costumers wanting their product.

Further, let's assume apples to apples and neither party needs the money to pay for their own support (since that's impossible in the non-cash flow property in SD).

Lots of bad apples.
