My basic understanding is you need to know all income and expenses for a period of time, so effectively you can't apply it to analysis of potential investments (pre-purchase), unless you use assumptions and plugs?

I'm making A LOT of assumptions here so any insight would be helpful. 

I go in with the assumption the numbers presented will be screwy.

Another set of eyes or two double checking the math and some of my assumptions wouldn’t hurt either :)Before I share this, I have a couple caveats: I am not a real estate investor.

The assumption package provided by the current mortgage holder is fairly straight forward except that it states we need a "sales (assumption) contract between seller and buyer."  

I imply from your assumptions that the units are currently way under-market (for my own back of the napkin math's sake, if you bought the property at the same 6.45 cap, then the NOI is currently ~$58k).

Scott Carson is likely under the assumption that you are already an active member of Facebook. 

I will say if things hadn't moved so quickly I would of done the financing of my existing properties first to have the ready to go as I made a large assumption of the values of my houses, especially since I have never dealt with appraisers before.

@Arpita Patel I would encourage you to have a firm grasp on the numbers and assumptions before taking an investment to investors or a lending institution. 

@Joshua Lindsey Please forgive me if any of my assumptions are incorrect.
