These are good sites with most of the ads are from agents. I live in zona universitaria... definitely above average and I think the average 3 bedrooms rents unfurnished in better neighborhoods you mentioned are $500-1000. What i dont like is most of these rentals come with a 1 month rental fee to the agent. I realize these agents have to earn a living but this aint Manhattan. Try to get one without the middleman.
If you can get a job with Carol Morgan, they provide housing. As for the prices.. I think that it will be hard to find a three bedroom furnished for under 20,000 pesos. When you see the dollar rental prices, the landlords are looking for folks who work for international companies. So they ask for and get the highest rents. While there is supposed to be rent control here, and the tenants are supposed to have the advantage, the reality is that the landlords really do. They are going to look for what the maket will bear, and a 10% per year increase... And will do no work.. nada.. zilch.. for the builk of them.
If you are really "making the move"// then you can stay in a furnished for one year, say, and then get into a unfurnished place which is likely to give you a longer term lease on better terms.
Here are the laws that govern your wife's pracitce of pyschology
Codigos y Leyes
If she speaks Portugese because she is born, say, in Brazil, and is a naturalized American, then she will have to go through the residency process probably before she is completely legal. (assuming she does not want to give up either of the other passports) ((I have a friend in this situation which is how I know)
If she only has a US passport, then she can become a Dominican citizen by an easy process because of her marriage to you.
But since she has three languages, she would most likely be a useful addition to any practice. Contact the Colegio and network.
Think about a two bedroom apartment for starters.. they are much easier to find.
There is one soon to be available in my building in Gazcue for $500 .. we think.,, good landlady, good location, only rattan furniture..
However everything in SD is determined by the tRAFFIC and how long it will take you to get to where you are going. So get the job first.. then look for apartments.
Other schools are St Georges, St Michaels.. And the Universities..
