Should I pay $100k cash for a rental property

[Steve S.]

My parents are willing to sell me a property below market cost to help me jump start my rental portfolio.  While I could write them a $100k check for the full purchase of the house, my concern is that will minimize the amount of other properties I could acquire with the cash in the bank for further leverage.

On the flip side, not paying cash is going to require outlay of several expenses that will probably cost me $5,000 or more I otherwise wouldn't have to pay if I paid cash.

How do y'all go about making this decision?  Is it an obvious answer to those out there with more experience?
