Getting a loan for a condo in las vegas

Hello biggerpockets community. I am currently looking to buy one perhaps two condos in Las Vegas, but I am being turned down by banks for getting a conventional loan with 20%. I wanted to know if this sounds about right, or if there seems to exist any options to be able to purchase without having to use up all the cash. Any help or direction would be appreciated. Thank you all in advance for the tremendous help.

Have a great day.
