But now i see how things work, i was comparing apples and pears there (from the business point)

I keep hard copies and scanned PDFs of important documents like leases, rental applications, and non payment letters.Like Brandon, I just use Excel to capture my costs.I also use my iphone.

If not, then you really aren't comparing apples to apples.

I used to be able to listen to podcast on my iPhone.

My questions are whether or not that's a good idea, whether I should count that interest only payment as a business expense when comparing properties or should I exclude that when comparing, so that I have an apples to apples comparison and a true cap rate in the traditional sense?  

So, fyi - the Podcast episodes are still alive at www.biggerpockets.com/podcast, but in iTunes and on iPhones and iPads and on Sticher... they might be gone for a few days. 

How can I get comps in the neighborhood without the help of a realtor (just using my iPhone or my computer).  

You have them fill it out, take an iPhone picture of their Driver's license (for ID, front and back) then have the Tenant Check company run them.Sometimes just this procedure alone is a Screen Technique;-)

Hey there Eric Benzenhoefer, I can share a good contractor with you tomorrow when we meet, I will share here that how I started out with him so I didn't take too much of his time, and I still do this.... was I hit the streets with the wholesalers that are cranking out the deals in the email blasts, and I would walk the property with my video camera, or my iphone camera, then I would load to my laptop while I was driving to one of his jobs, and then took only five minutes of his time to go over every detail, then if it made sense to him, he would get over to the property again, or I would drive him to it, so his office was mobile, and this has worked out very well for us both!

To throw out ideas like the present value of money in relation to a sale price, is apples and oranges.
