Let's say company net assets in bank is $40,000.00 creating a system quarterly that will utilize 20% of that towards marketing.So January, February, March - $8,000.00 total between Direct Mail campaigns and other forms of marketing.  

If you turn your building into 2 condo's, then the comps you mention might be able to be utilized.  

Your numbers are off - capex really depends on current property but people like to carry 10% of rent ($130), repairs are another 10% ($130), vacancy again depends on area but if you assume 8% ($104)Big question is who pays utilities.

It's all about those utility bills people!

It's been the best decision I have ever made as now I work part time for my fathers scrap yard and utilize as much time as possible furthering my investing career.

Are utilities metered seperately?  

These numbers may include CapEx, Vacancy, Utilities (if tenants are not paying them), and maintenance/ repairs. 

Are you going to put utilities in?  

Does anyone have any suggestions on the documents I should ask for, other than rent rolls, and utility bills? 

Appreciation is nice, but cash flow is instant and much easier to predict.I rented rooms at my first home, it covered the entire mortgage and most of the utilities.
