Retirement accounts are designed to be invested passively (i.e. rental property, trust deed, note fund, syndication, etc.)

You will want to setup a bank account that goes with your LLC.

Equity Trust is certainly one of the biggest and well known custodians of SD IRA accounts, but my experience with them was not great. 

I really don't want for tenants to mail their checks or directly deposit it into my account.

I was taken aback by the sheer Income potential that was compounding in someone else’s account while I was sitting on their balcony...the calendar was booked the week before me, and the week after we were set to leave...assuming everyone paid the same rate I did...I was blown away by the $6000/month earning potential...Does anyone here have experience  with this sort of real estate investing?
