Private lending to buy foreclosures

[Abe Naroth]

I am new to RE 'investing'. Based in Katy, TX, I have a mortgage and my DTI ratio is 30%. I have roughly $100k in my emergency fund and would like to venture into foreclosures. However, I do not want to liquidate my emergency fund, but rather use it for repairs before I flip the property which I buy in foreclosures. I have a partner who can take care of fixes. Would any lender be ready to issue cashiers check for an amount which I request for ( to be used during the day of the foreclosure), with a lien on the property which we buy (the property is subjective to what we bid for and not definite). 

Pardon me, if this is a basic question - again, I am new here.
