​Non itemized method for estimating repair cost

[Floyd Orr]

Hi guys I first heard of wholesaling real estate on 9/23/15 from a customer at my day job and set my action date to be 30 days later which happens to be my birth date. My action date is a few days away and I have learned a lot about wholesaling, and have been putting a system in place to help me efficiently work my business.

One of the things I have read about is how to figure out how much it will cost to fix a home from a very good book I brought on this website by walking through house and itemizing cost one by one and it has giving me a good understanding of that method.

I have come across others who use another method that does not rely on itemizing cost. They simply find out what other investors in the area have paid for similar houses.They assign the contract around the same cost using comps and using good old sales skills to put the house under contract as low as possible. Just that simple.

Does anyone have a good resource that can help someone master that method, using tools outside of mls or websites like Zillow? I hear there are other services that can be used for comps that people are successful with, some are paid and some are free and does not require having to become a real estate assistant for mls access. I'd like to use the  "itemized method" and the "investor purchase method" when I come up with my numbers.

Does anyone know of a book, program or have used that method to purchase and assign contracts with success based on what local investors are already doing and can share a tip or two?

Thanks in advance.
