The key is to come, talk to people in the know on the North Coast- not realtors with a financial interest- and look, look, look. About 1 1/2 years ago I sold my Perla Marina property, not losing one peso after buying it in the peak of the real estate market. It was located in the middle of the project, away from the fincas which entice intruders, included 2.5 lots, and was decorated and kept up to American standards. It included a guest house and a work casita. It sold for $430,000, with reduced realtor commission, paid in part by the buyer. It was a cash sale.
The best advise for anyone, prior to purchasing anything in this country is to make friends and speak with those in the area where you want to buy. Make sure those individuals have no business interest, yet are in the same socio economic group that you are. Make certain that they have lived here at least 5 years and have established roots in the community. Ask to meet their social group to know whether they are your kind of people and you can trust their advice.
I would never take anyone's advice on a forum, including mine. Follow my advice, though, and you will be fine.
For me, when I sold my property to buy a condo, I looked at every single condo development on the North Coast before deciding. Even though I had lived here 6 years at that point, I didn't take anyone's recommendations but my own.
Good luck. Choose wisely.
