Question about how SBA loans work when combining real estate with the business.

1) If there is a combined Business + Real Estate opportunity - do lenders a single loan for a longer period###-###-#### years)? Or, are we looking at two separate loans, one for the business with 10 year term and another for the real estate at a longer term?
2) I also heard that if the real estate is worth more than 50% of the total business opportunity, the period becomes 25 years (for a combined business + real estate loan).

Any input here would be much welcome! - Thank you in advance.
