I got a call/text back on a mailing, what should i say?

[Pat McGrath]

i actually got a call back from a (small) mailing i sent out. After a few phone messages back & forth they are txting me asking what my offer is. I want to reply back that i have to find out more about the property first before i can make an offer. I was thinking about saying i have to but it as an investment & the #'s have to make sense for me, but not mention specifically that im an investor. I am going to make sure i try not to waste their time or mine, if we are far apart & will put them on another follow up mailing list & try to leave
