What are a good set of questions to bring to the table when being offered a multi-unit portfolio opportunity with 100% financing?

[Sonia Spangenberg]

We have beginning experience with SF home investing and are currently using cash for smaller deals.  I just want to make sure we are asking all the right questions when we evaluate this next level deal.  Cap rate is supposed to be 13,  there is going to be a new property mgt firm in place, the local rental mkt has a shortage of properties.  It sounds like a no-brainer but I am sure there are more questions and verifications such as price/cash flow amt.  Please suggest a list of questions to help me make sure I am covering all the bases.  Thanks
