Unless you have a history in the rental business, most lenders today are going to require a buyer to have the ability to pay for a property without rental income from that property.
As a second approach, have you considered qualifying for a property purchase with a family member or friend to split the expenses of ownership? It's just an idea, as many owners are doing this until they see if the beach rental market is for them. In time, you can "trade up" to a place of your own, but this could get you in the door until then.
