Just finished Nickerson's book, let's discuss!

[Therese V.]

I recently finished William Nickerson's book "How I turned $1,000 into Five Million in Real Estate in My Spare Time." It was a really good read, but there are some things that he does or recommends that I have questions about.

He was investing decades ago, home prices were lower but so were worker wages. Do you think what he did then is replicable now? 

He talks about the units being furnishes, is that something that is even a thing anymore?

He advocates the buying at one level and then upping and upping and upping and then starting again for more buildings. How realistic is that approach these days? 

The example he gave are of people trading properties, 1031 exchanges, etc.  Do people actually "trade" properties? 

If you've read his book, what things do you wholeheartedly agree with and what things do you just disagree with and why?

We're about 18 months in on our real estate journey and have 3 rental houses (just closed on the third last month). I certainly found the information he shared about porches being a way to drop the value of a property but an easy fix and low cost to increase the value and get a good deal on the buy. 

Any more seasoned investors have thoughts on this book, where it has helped you, and what information should be changed to  match real estate investing strategies today?
