What arethe financial requirements to purchase 15+ unit building?

[Quincy P.]

I recently purchased a 4-plex and would like to start setting up for purchasing at least 15+ unit building in the Minnesota/Wisconsin area. I am wondering how cash reserves are reviewed for such a purchase? I would be pulling the down payment from IRA/401K and looking in the price range of $700K - $1.5MM. How much cash on hand would I need for this? Is there any other things I need to be aware of? Sorry for all the total newbie questions, but I need to start planning now. It's either a multi unit building or a liquor store to plan for in the next 2 yrs.
