Investment doesnt sound feasible to me unless youre investing a lot lot more than 30 K
30k sounds very expensive for Goa, looks like you are being "paddy priced". Even UK agents are selling this part of the world below 10k Stg, so local prices probably less.
I assume you have already figured out the exit strategy -- who will buy the property from you, local demographic, tax implications, currency variations. etc.
