I agree with Michael. A condominium is your best option to get the biggest bang for the buck. Myself and company, Oceanfront Guru Real Estate Sales and Development, we specialize in the condominium industry.
You are in luck because Myrtle Beach is currently in a Buyer's market meaning we are in a "buy low now, sell high later" phase.
In regards to where to start off, you need to find out what your buying power is (cash or finance), price range (current cheapest ocean view is $24,900 with $250 HOA/ current most expensive ocean front is 2.4 million)
If you want some more help, feel free to call, text, or email.
