Touring a 12 plex

[Abou C.]

Hello

Touring a 12 units tomorrow at 10am with a agent, property been on the market for 1 year, currently just two tenants. From what the agent told me a family owns it, but I discuss they never cared to update units or get more tenants overt he year.  two buildings 6 units each  priced at 225k each totaling $450k.

I am wondering where that $22k would come from, if there is only two tenants now, landscape need some tlc, looked through window units need updated from what i can see. 

What things should I asked or look for when meeting with agent tomorrow?
