My crystal ball says higher inflation from QE then borrowing costs go up since capital is hard to come by and you have a sluggish market for some time.

Bottom line is the whole health plan centers around healthy people paying a premium so the rising claims by baby boomers about 20 million retiring in the next 10 years and the poor will get coverage.

Do they really just keep pumping out stable cash flows that grow with inflation or do you end up with a bunch of decrepit houses that no one wants to rent?

With inflation of both values and rents they will look like geniuses.

Do you think, in some weird possible future as values rise, we see a rise of this type of ex-borrower complaint?

Donald Trump loves building high rise apt buildings.

Well, this was the point where they began their rise to complete market dominance.

In addition, you might find out that you benefit better from your re investment if you sell it ways before the 30 years or inflation shoots up and with it rents and mortgage rates and suddenly the 0.25% difference in interest rate is marginal.

I am thinking of an area with less hi-rises and more small retail which is fun for pedestrians (boardwalk-style?).  

What if the property's value rises to $2 million two years later?
