(Hopefully) my last question about running comps

[Victor Maddox]

Ok so if I'm running comps and I come across a property where there's only 1 or 2 comps that have the exact same number of features as the property I'm looking to wholesale, but there are a few that are close but different by one feature (say, an extra half/whole bathroom or an extra bedroom) would it be possible to include these in the comps and adjust the numbers so they match the property i'm trying to wholesale? 

If so, is there any general number that usually works best in this regard (I.E. take off/add $5K for an extra bathroom, etc?). And does this work with garages/basements too?

Sorry for all of the questions, I'm just at the last hurdle before I can finally start cold calling and I find a lot of houses where I can't find exact matching comps.
