Should I be more flexible with my search criteria and parameters

[Maurice Selva]

I been runing the numbers and filtering through a ton of properties over the past few months and have yet to make an offer on anything that hasn't already had multiple offers on it and gets snatched up. I've had my realtor help me identify 2-3 zip codes that are considered B-C plus neighborhoods and continually sends me daily or weekly MLS listings but they either get weeded out because they are located next to dump properties where no one on the block has any pride of ownership or the are located next to factory or some other undesireable property. Am I being too picky or should I be looking in B- or C neighborhoods and stay focused on buying something needing tons of work in a great area? The other thing I think that I am doing is when I am running the numbers I am using California price sheets instead of local vendor cost/price sheets. I feel as though my cost figures are coming in too high thereby eliminating a lot of properties so that they don't meet my cash on cash requirement, any advice on what I should do?
