You can do a few things to minimize the risks-there are long lists on the internet but 2 key points in my opinion are:
-see if the project has title insurance; if you are getting title insurance, that should give you a better level of protection (having said that, we bought without it but with assurances that it is on the way). Title is very complicated in Nicaragua due to confiscations of land that occurred during the civil strife 20+ years ago. Many of these issues have been resolved; others remain outstanding.
-if more than 5 units/properties are being sold and the project is being marketed in British Columbia, see if the developer has filed a Disclosure Statement and if so, make sure you receive a copy (ok-yes we did buy without this but only because they had filed and had it rejected so it is being resubmitted)
-a new requirement for title transfer is the receipt of a Letter of no Objection....check to see if this document has been obtained for the project (again, our properties do not yet have this but an application has been made to receive it)
-if you are buying on the Coastline, check the status of the proposed Coastal law: this draft law was not passed during this sitting of the Nicaraguan legislature; however it is expected to be reintroduced either in the fall of 2008 or the spring of 2009. This law will affect ownership and buildability on coastal properties.
And of course, talk to people who know the country better than you do; hire a lawyer (although don't assume that will protect you to the same extent it will here) and don't spend more than you can afford on foreign investment! Other than that, enjoy!
