Do you make your offer right away?

[Marilyn A.]

I was wondering how you go about making your offers. What I mean is, when you first go out to see a home, do you make an offer on the spot? Or do you go home and think about it and call them back with an offer?
Do you ever make offers on the phone or strictly in person?
Do you mention on the phone or by email when you're setting up your appointment that you're an investor and your offer may be low?
Would love to hear any words of wisdom on this as I'm considering making several offers this weekend. Well, I mean I have several homes I'm considering making offers on. If one is accepted, I will probably finish that deal before making more offers, since I have a very small amount of cash.
