Do all realtors want a pre-qual before showing?

[Jack Middleton]

We are wanting to look at a couple places in Florida next week. We asked to see two properties and the realtor wants us to pre- qualify before she will show those to us. It seems that lately when we ask to look, we are always told we need to get pre qualified before they will show them. Is this normal these days. We don't want our credit checked jut to look at a house or condo! Jack and Cheryl
