One other factor is the parking.  

While cap rates (like comps) are interesting, I generally do not use them as go / no go for making a purchase decisions.The determining factor is what options the property presents in relation to your particular investing strategy that will allow for forced appreciation and increased NOI.Best of luck,John

I am a factory worker 10 years.

The one equalizing factor is TIME.  

One key factor is were all parties involved notified of the sale and is there proof that this was done.

I am also working with Finance Factory as they have the lower fee.

At least the Jeep factory is safe for quite a few more years, as they are soon coming out with the new design. 

Another time factor is the time to find properties that meet the criteria you choose.

Another factor is the time duration it would take to get an appraisal done.All in all, if property condition is something you'd like to be accounted, I would select the real life appraiser.

I am an engineer and currently work for a major ag/construction/lawn equipment manufacturer (I'll leave it to you to guess which one) at one of their factories in my area.
