Often these items -beneficiary and wills--are very outdated. 

Some homeowners even rely on outdated autovaluations like Zillow's Zestimates for home values.

One is a fixed dollar amount with negotiated move out date.

There are millions of home owners who still can't sell their property for what they paid for it 10 years ago, and have 10 years worth of outdated color schemes, wear and tear, depreciated appliances, etc.

I feel the book is out dated long time ago when someone can do their regular job sitting at Starbucks and even multitask juggling between work and investments. 

Out-dated heat is kerosene and I think it needs to be replaced.

Lastly you have tons of people scrambling to buy a house (homeowners and "investors") with low inventory in some markets... this again means you're paying close to market price for something.You might find it's easier to find a property that's nearly rent ready (maybe needs minor updates) and is outdated but still good condition.

That's another loophole not addressed.Signing a new fixed term lease contract gives them a future move-out date, but is technically not an eviction.You're not stuck with a below market tenant forever.

Maybe heating abandoned buildings, purchasing out dated buildings via Imminent domain, or hiring local property managers to lease out units on behalf of the government would be potential solutions.

Some books are outdated or misleading or narrowly focussed on a niche market.
