Traditional loan or line of credit

I have few properties that I recently bought with all cash, for roughly $1 million, the appraisal came at $1.5 million.

So what would be my best strategy to cash out?

I talked with some bank, they will lend 75% of the purchased price.

But it would be really good if I can get 80-85% of the appraised value, and use that cash to buy additional properties.

What do you guys recommend any ideas or suggestions for me?

Thanks in advance!!
