My first real estate investment. I need advice!

[Chad Duncan]

I am currently looking for a multifamily home in the Portland Oregon area. I am looking for more of a 4plex than anything else. I am pre-approved for a loan as well. 

I want to start offering on some places. I feel that I need a contract or something that gives me time to make sure the property is worth investing in. 

What can I do and where do I go to find out more on putting a property under contract? 

As well, what are the main things I should look out for that makes a good deal into a great deal? 

Thanks
