Beach front property in San Juan

OK. I have a friend that owns a 4 bedroom property in San Juan Puerto Rico. She says its 2 block from the beach. She now live in the States and says she is about to put her San Juan home on the market for $125,000. She says in San Juan, $125,000 is very expensive.

I’m thinking, this would be a great oppurtunity to start a timeshare. I looked at other sites on the internet and time share in San Juan retail anyware form $5,000 to $10,000 per block of time (one block of time would be 1 week)

My question is, does anyone here know about selling timeshare. Would this be a worth while investment?

Can anyone out there help?
