You would need to have them issue checks from the IRA for any expenses associated with operating the property, just as all income due to your IRA would need to go through them.If you establish a land trust with an investment partner, then that trust could have a bank account that your partner could operate.  

In finance and accounting we look at a "Quick Ratio" (also known as the Acid Test) this shows the ability of a company to meet obligations, but this only looks at current assets or liquid assets and current liabilities, real estate is not a liquid asset.So we move to other ratios like "Current Ratio" and "Cash Ratio" these to help to illustrate the ability of a company to cover current debts.As to mortgages or long term debt, coverage is difficult to predict due to uncertainty over longer periods, but by looking at the current coverage and cash available we can see what funds remain for these other obligations.Most everyone is familiar with the debt to income ratio we suffer through at a loan application, say 24/36, meaning that you should not pay more than 24% of your income to current liabilities, revolving accounts and car loans, the 36% includes the 24% to establish your ability to cover the mortgage, total debts should not exceed 36% in this instance.
