Proof of funds question

[Account Closed]

Hey everyone, I wanted to bid on a foreclosed property and the real estate agent required me to submit proof of funds as an investor. I don't have the funds for it however my partner does and he will pay for half the value of the property. We're trying to have a mortgage on the property under my name to get a good rate as a first time home buyer. Did anyone come across a situation like this? What ways can I provide proof of funds if I personally don't have it? Thanks in advance.
