Would someone mind taking a quick look at this?  This is our first deal, so would love to have another set of eyes.  This is four condos that have tenants.  I realize Cash on cash is a bit low.  We have been trying to shoot for 7%.  However, we cannot find anything in our area near this. The list price is $320,000- so we aren't sure if we will get this price or not. Also, do we need to have "vacancy" included if it has tenants or should this be there for future issues?  Thoughts?
