Pre-Qualification concerns on first offers

[Rich Thoms]

I have a question that is probably a bit foolish. I am concerned about pre-qualifications and Hard credit inquiries against my report. 

The situation is that I have been looking for deals for many months and now see one that ( fingers crossed) I may want to offer on. obviously this means I need to have the pre-qual letter handy to have as part of the overall offer. 

I understand that when looking for mortgages that banks and credit bureaus see hard inquiries all within a certain time essentially as one hard pull.  What concerns me is if the deal doesn't workout  and i do not see another property  for a while (6 or more months) that I will then have a situation where when I do get a mortgage for an investment, I will have yet another hard hit.

How are people here handling this or am I looking at this in the wrong way
