Will I be under any presssure to make offers fast?

[Antonio Bodley]

I want to contact all the motivated sellers on my list to prequalify them before making any offers upfront. Can I just get prequalification info about their homes first without being pressured to make an offer upfront even if I was to go by to look over the house? I know they are motivated to sell fast, but I need to look at other options first so I can compare which is really a deal and which is not a deal.
