I actually met with the agent directly as it was his childhood home, and he wanted to know who was going to buy it.

For those interested, a combination of mortgages with no “due on sale” clause, mortgage companies loose due diligence, and title insurers willingness to “turn a blind eye” to practices that wouldn’t pass scrutiny now, resulted in tactics like the “second mortgage crank” which not only allowed investors to purchase properties with no money out of pocket but allowed investors to actually walk away from closing with “cash in their pocket”.

It makes lead management way more efficient since they get to focus on people who actually want to do business. 

What Actually Works:• Ask questions• Understand their “why.” 

They claim that their clients are seeing a large return on their investment but would love to hear from somoene who has actually worked with them. 

Nobody ever went broke over a duplex, I know this now,  but I have to admit I had some serious doubts about this when I started 16 years ago, I bought every course I could find, already on CD's, this was post cassette tapes lol, and I paid RichDad Education for a one year coaching program (turned out my coach was a girl in a call center without any actual experience). 

Is just the fact that no garage could be a no go for some buyers enough to build it even if it only raises the value by the actual cost?

Yes, they are actually selling individual units as well

Some can actually be pretty cheap.

We actually CAN'T explain what we are seeing if we are operating on the "purely rational actor" hypothesis (as you implicitly observe), we MUST include highly irrational and emotional individuals to explain what we are seeing.- Investor uncertainty.
