Credit Pull impact when buying multiple properties within a year

[Mike Dugan]

I believe from reading posts here on BP and other sites that to have my credit pulled for a new rental property will probably cost me about 5 points on my credit score for about a year.  I am planning to buy 6 houses in the next year which will require me to have my credit looked at every couple of months.  Based on the above assumption, am I going to end up with a 30 point drop over the year?  Any way around this?  thanks for any input....
