buying with cash vs borrowing

[Calvin Lang]

I currently own (no mortgage) two homes and I am living in one and renting the other.  I am looking to purchase another investment home for income purposes and I do have the cash to purchase one property outright. I am not sure if I should finance a small part of it and save cash for future real estae investments or just pay cash.  Any insight or experience anyone can share would be most appreciated.  Thanks,   Calvin
