You do not want to have to pay for a house in flames out of pocket.5.

Telling a child their father has died or a daughter that her father has passed and we won't be taking him to the hospital because I had pronounced him dead at the scene QUICKLY makes you learn that ripping off a bandaid and quickly exposing yourself as vulnerable WORKS.

I just don't like the fact that their immigration status leaves them vulnerable to unscrupulous individuals.

That should make them less vulnerable to market changes compared to a company who say makes heavy brake pads.

Then I'm vulnerable to lawsuits.

@Mehdi Khachani the biggest issue is security as your site would need SSL and even then having another payment site run within an iframe on your site isn't secure as iframes are vulnerable.  

I'd be vulnerable just because I don't know what I don't know. 

And the big data space is even more vulnerable because most of these companies dont make any money.  

Does it protect me as a landlord more (in case of need to evict) or make me more vulnerable?

Not really interested in commercial loans or anything I have to refinance every 5-10 years that would leave me vulnerable to the fluctuation of interest rates.Any recommendations would be appreciated.
