It's why companies like Apple will have billions of dollars of debt and billions of dollars of cash on their balance sheet at the same time.

I've got a Master's in Real Estate (investment/analysis/development/construction) from Baruch College here in Manhattan and I interned putting together request for financing proposals for a pretty large investment firm (a few billion in assets) here in the city in the past.

@Daniel Busby - I am not sure why you are looking at this as a problem, with legalization there is billions of dollar worth of new industry developing including Marijuana theme base wedding.Welcome to new worldVivek 

There are so many commercials on the TV and radio for medications because they (the drug companies) are making BILLIONS of $$$ off of people who are suffering from every day feelings.

lost relative to inflation aka YOUR BILLION DOLLARS should've generated a stronger return. the investment itself, while losing relative to inflation, still has netted you 10 million dollars. could you find a better investment for a billion dollars, sure, rather easily I would guess.

I figured if I was going to be responsible for handling multi-billions of dollars over the course of my REI career, I had no problem paying for it from those that are/were the best. 

There are multi-million and billion dollar companies that are one LLC!

Trump does admit real estate is an appreciation business and claims 9 billion out of 10 billion is free and clear so he just might be right...well not might be:) He says he bought casinos for cash flow.

Don't get me wrong, I'm not saying that the big boys with billions in capital and decades of experience can't pull it off, but not a newbie ... and there are plenty of examples of the big boys falling flat via the same risks when trying to expand.

Your location will play a big role on both the payback (electricity rates, incentives, ability to sell surplus generation and for how much) and whether tenants will pay a rent premium to live in a sustainable home.Our local utility is late to the table when it comes to renewable resources (having recently spent a billion $$ rehabbing a nuclear power station that was end-of-life, it's clear their focus is elsewhere) and provides very little incentive, and no material assistance, for citizens or business owners to generate their own electricity.
