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.

Now tenant is suing for security deposit because of the charges I applied to security deposit.

Part of me wants to secure the property and sell it, i think this would be a easy sell. 

We buy wholesale deals and do private lending on secured flips locally for professionally prepared deals with all the i's dotted and t's crossed.  

These investors are more highly correlated with more sophisticated money and are unlikely to invest in projects like vacation rentals.
