Holding Sub2's

Hey all,

I am new to the S-2 game and have not yet done my first deal. I am actively looking and have just started the paperwork to roll over my IRA to a self directing Roth where I plan to do my purchasing.

I have been a landlord for more than 15 years and hold over a dozen mortgages.
My question is, with the possibility of the bank calling a note when I become the new deed holder of a property, is there more risk of this happening if you are in for the long haul (10+ years) as opposed to getting in and our as quick as possible?

Thank you very much
