You do not want to get too many details over the phone. Just the main ones. Some landlords are asking the following:
1. The number of occupants there will be. 2. If there are pets, kinds and numbers. 3. Ask if any smoke if you have a no smoking unit. 4. You can ask what their income is and what they believe their credit rating to be. This will be checked out later but if they give you a low number you can shut off converstion at that point. You can shut it down too if the income level is less than 3Xs the rent. 5. Ask about employment and how long on the job.
