I have secured my 2nd property this year (and overall). 

Just tried it, but my browser security denied it saying tested site and found security risks.

I also take the same security that a HML would do (i.e. first position on the lien, insurance beneficiary etc). 

In order for both side to have “skin” in the game I have either a $50 a month pet rent OR one months security deposit.

Some credit cards are not hard to get and if necessary you get even get a "secured card"  There are sites that will tell you what cards are the easiest to get and even what credit scores are necessary. 

I am challenged by your courage to give up security and dive head first into real estate.I could totally relate to your dad saying, "not to trade security for uncertainty".That is the mantra of typical Asian parents, especially 1st generation immigrants.  

Hard to believe as almost all banks employ field service companies to verify and enforce that the property is secure until closing.

In my opinion, it's a secure and reliable way to get started in the real estate field while starting to build some nice equity.

Here we have 2 weeks to return remaining security deposit.  

The previous owner did not have/give up security deposits.
