Welcome to the community, Jim. You will find that Uruguay has very interesting beaches to offer.
Who is selling you an oceanside not yet finished in Malvin, which is supposed to be half way between Montevideo and Punta del Este? This sounds like a nice piece of swamp land in Florida, if I may say so.
Anything between Montevideo and Punta del Este is not oceanside but riverside (although the Rio de la Plata can be hundreds of km wide and has an increasingly high content of salt the further east it gets).
Malvin is not half-way between Montevideo and Punta del Este but a part of Montevideo. The Rambla is nice in most of Montevideo but the beach is much more populated than it would be half-way between Montevideo and Punta del Este.
Please be careful, if things do not add up. Search Malvin on google maps. Ask the sales person for the pin for google maps and a prospectus or a web link for the development. All of these major condo building have at least one or the other.
If you send me the pin by private message in the next few hours by private message, I can offer you to drive by and take a picture. I will be in Montevideo on Tuesday, but I live in Colonia.
Happy real estate hunting.
