Lender options for an auction in Iowa

[Jeff George]

Hi everyone. 

I am looking at an auction house that will be a owner occupant house. 

I already own a duplex that has a mortgage and a house that’s free and clear and will end up being an investment property in a few months as well.

I also work three jobs (one under the table and one with tips) and can show good income as well as have reserves for all debts for around 4 years worth of payments. The majority are in a taxible investment account that I’d rather not empty to buy in cash.

what kind of options do I have and can anyone recommend a lender that can close within 30 days? I have the 10% down payment needed for the auction in cash. 

I’m not a financing wizard so I figured I’d ask for help where people have knowledge!

thank you!
