A blend and extend amendment can affect loan terms in a few ways. First, it can reduce the risk for the lender by pushing back the lease expiration dates for tenants, which can help ensure that the building never falls below a reasonable occupancy level. Second, it can reduce the monthly rent, which can reduce the amount of income the lender can expect from the property. Finally, it can also include other tenant concessions, such as a contraction option, which can further reduce the amount of income the lender can expect from the property.
