So you have cell phone, home office, computer, software, utility, supplies and other expenses like that which will be deductible and should be reported on page one of your K-1 and then you will have the expenses which are directly related to your inventory or your home that you have purchased to sell.

Send me a PM and I will give you his cell number.

With my cell phone I can continue to manage these properties anywhere in the world.

I would also look at the local and online real estate business journals. 

I don't have a phone line in my office outside my cell and would like to set something up.

I'd suggesting finding a local accountant, have them show you things once (like how to do a general journal entry for a new property).  

Is it better to just use your standard cell phone? 

Best to get tons of insurance a hold personally on the first few properties, but there are other factors.You may need to look at a business license with rentals or your LLC, one for each.Off had suggestion, look to a Series LLC in TX, one cell may own, the LLC manages or another cell could manage.

You should only need to fill in the highlighted cells, however I left them all unlocked so you can see my formulas and can tweak them if you need to.I'm always welcome to feedback, if you think there is info I missed, miscalculated, or a way to make it clearer, let me know.http://www.biggerpockets.com/files/user/ericksonss10/file/commercial-rent-rollI hope it helps someone out!

@Sean Sloop   I am not a retail lender but I was reading one of our trade journals as I like to keep up.and for FHA loans.. the new underwriting rules require 2% of your outstanding balance to be used monthly against your DTISo if you have 25k in student loans that will be 500 dollar hit to your DTI  which is pretty significant for most.
