How do you categorize your earnest money payment (and eventually the rest of the down payment) in accounting software (like Wave or Quickbooks) when purchasing a rental?

I know the down payment isn't tax deductible, but I believe some of the closing costs and such are.  However this question isn't so much about that, just trying to understand the right category for the actual down payment itself (because I don't think it really falls in to an income/expense category).
