Port Aransas Texas or North Padre

We are first time investors who have narrowed it down to Port Aransas or North Padre Texas. Looking for a house that is  2/2 or bigger with a price tag of 225K. Close to beach as possible, maybe with a view if possible. I've seen a few and now they went pending. We would like to use this as a short term rental. 

Begining to get a LLC together and looking for lendors. Anyone know how to get investment property for less than 20% down?

Is there anyone out there who may be able to help with this area? Any input would be greatly appreciated. Than you all
