Living with friend in the same unit I could do indefinitely though. 

We extended multiple options, offering you the choice to either cancel or indefinitely pause the account, all while retaining access to the program.

An additional pro is the idea that the taxes can be (essentially) indefinitely deferred through 1031 exchanges. 

Is the present upward motion sustainable indefinitely or are income/wages, business investment and taxes at some point in time going to take effect. 

You should consider classifying yourself as a real estate professional, this would allow indefinite deductions on your tax return. 

My observation is that most investors overpay, overleverage, have very little in reserves (if anything), and have one exit strategy that is completely dependent on the market rising indefinitely.

If my rental income fell 50% (which has not happened nationally since at least the Great Depression), I could still make payments indefinitely but because the loans are non-recourse it may not be smart to do so (depending on what has occurred with property value).I suspect that negative cash flow does not imply over leveraged is the point that many of the cash flow over appreciation are missing. 

Thanks to Covid, the first two are on indefinite hold but the last two I can still do.

Other than bringing the deal to somebody’s attention why would someone want to get a loan on this property and have to keep you around as part of the deal for the indefinite future?

Here’s an example of the type of structure that could work in a horizontal hotel model (this is also why I mentioned cap rates and commercial zoning)Either way, I really appreciate you weighing in - definitely got me thinkingThough that's a really cool looking concept house, imagine the parking, driveways, septic, utility lines, water lines, etc. that are needed to actually service such a structure.
