Probably not if it is an OO real estate...you still have to qualify the loan to be federally compliant. 

Many of those years I was a leasing agent for the city of Chicago.

The way I would approach this is:-Ask your agent to find out if this is a legal 4 Family-Ask agent to confirm whether the current tenants are paying rent (rent roll serves as proof). 

Could be an agent you work with, someone you partner with on a deal, a contractor who can give you advice on projects, or just someone you met and clicked with at a local meetup or here on BP.

Hi.I was wondering how to find and contact the seller agent since I found the property for sale in Zillow without accessing to the MLS.

I went to UB as well and am now an agent/investor/property manager here. 

Tucson federal Credit Union were the ones that provided financing.

Im hoping the numbers work out. jijijijiji Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I used a website called agents invest and the deal was brought to me.

I am an agent with access to MLS, but there's no good way to search for vacant parcels.
