Find out the true vacancy rate for the immediate area.

True--good point, thanks!

True, you can maintain returns at 10% - but it can be hard to actually buy into loans (they frequently get canceled), and it isn't very easy to cash out (sometimes you have to sell your note for a discount, and it takes time as well).  

Have you found this to be true?

The definition of true passive investing is this : "regardless of any time you spend on that particular investment, whether it be 5 minutes, 5 hours, 5 days, it has absolutely no influence on the outcome of that investment".  

It is true, that in order to use "market value," to cash out you'll need to wait a full 12 months.There is an exception to the above though.

The tax assessment is usually a very poor way to judge the true value of the property.

Unbelievable, but true.

Very true Matt!

My agent thinks it is not true.
