Rental Property putting minimum down vs paying all cash

[Deepak Walia]

I am looking to purchase my first rental property and wanted to know thoughts on paying the minimum down payment vs paying all cash.  I will lay out the scenario...

Purchase price of condo $130,000

Down payment $30,000

Monthly HOA+Taxes $500

Monthly rent $1500

If I take a 30yr loan, I will be making approximately $500 net per month.

This is a $6,000 / $30,000 = 20% return on the investment of $30,000

If I pay all cash...

I will be netting $1,000 per month

This is a $12,000 / $130,000 = 9.2% return on the investment of $130,000

My question is "which is better?"

One part of me says that its better to use other people's money to make money.  If I put all my cash into it, I will not have much left to buy anything else.

Any thoughts would be appreciated.
