Property prices in Mauritius

I am hoping on lots of advice as I am looking in buying property here.

Well, one thing to know is that foreigners (ie people who don't have Mauritian citizenship) are free to rent in Mauritius. The only way for a foreigner to buy property is through the IRS and RES schemes, which have a minimum price of $500k - but mostly start at around $700k. These are mostly apartments. This is to prevent foreigners from making the property market inaccessible to Mauritians.

property prices for plots of residential land vary from 2000 rs/toise (one toise equals roughly 3.8m2) to 50, 000 rs/ts (sometimes even more) depending on location and size of plot. Prime locations are the "good"quarters of the urban centers and plots in coastal areas with immediate access to the beach. The cheapest land are larger plots in remote areas without good infrastructure or particular attraction for the average mauritian (although you might still find underrated gems  if you don't mind living in the "wilderness"). The vast majority of expats with no mauritian relations prefer the coastal areas (Black River, Flic en Flac, Grand Baie) but as graceunderpressure has pointed out quite rightly, foreigners have only limited possibilities to buy property here. Prices for homes (depending on size, location and quality) start from ca. 1000,000 rs with almost no upper limit.But let's say for 4,000,000 rs. you can get a decent newly built 3 bedroom house in a decent middle class neighbourhood (albion, roche brunes,) the price for a newly built simple apartment in a similar neighbourhood starts at 1,300,000 rs. When you buy or sell property you have to pay 5% land transfer tax. Notary fees (only when you buy) are 1.5-2% of the declared value, agents fees 2%. You can rent an acceptable house in a remote area like from  7000rs/month, in the coastal areas between 15000rs and 60,000 Rs (although there is no upper limit). There is less choice for flats, (mauritius is a land of houses) and the rent is roughly the same.

Tamarin and Black River for the hot weather and the sublime sunsets.

Yes, agree ...if you can cope with the heat and love a good sunset from the beach then I'd suggest Tamarin. If you like a cooler climate where you won't need aircon in your house, then Vacoas/Phoenix or Floreal/Curepipe are the places to be, plus these towns provide easy and quick access to every amenity you could ever want.
