Sometimes I help people with real estate over here in Santo Domingo! But your question is very vague to give a proper answer to it! For rent it is may be RD$ 15000 to 60000! The price range is very unusual, but this is one of the topics of this country! And it is very hard to find something suitable for rent anyway and if yes - you would have to do the resauration of the place!
To buy is easier, but you always need a lawyer to check up all the points like documentations, title (very imp.), and if all bills are payed (electr., water, tel., taxes etc. etc.)
Here the prices go from RD$ 2500000 to 8000000!
Now for your help the exchange rate is in the moment RD$ 16.85 to USD 1.-!
