Our experience

Our own experience when we considered renting an Ixtapa condo may be instructive....or not.
In Oct/13 we had an Ixtapa rental agent show us three Ixtapa condos. We wanted to move in immediately and stay for a full 5 1/2 months. All three were each 2 bedrooms, (though we'd wanted only 1). Two were away from the beach, one was right on Playa Palmar.
Those away from the beach were asking 8500 pesos/month, plus electricity, no drinking water, cleaning or laundry services provided. At one, the pool appeared to be unusable, at the other there was no pool furniture or people. While the units were certainly acceptable, the pool and grounds were not - victims, I suspect, of the apparently widespread problem plaguing many condos in the area: absentee owners not paying their monthly maintenance fees.
The other two bedroom unit, on the beach, was asking 10,500 pesos, but would have accepted 9500. Again, plus electricity, no drinking water, cleaning or laundry services.
We asked the rental agent how much electricity might cost, and were shocked when she said: "From 2000 to 4000 pesos every two months, depending on how much you use your air conditioning."
When we added everything up, including the costs to commute 5 or 6 days/nights/week into Zihua and La Ropa, we figured the monthly cost would exceed our budget, and we ended up spending that whole season back at our usual digs in Centro.
This past April, before we headed home, we thought we would see if there was anything available in Ixtapa for the 2014/15 season. We found a unit for rent - a one room studio - through the Message Board, which happened to be in that same on-the-beach condo. We arranged to meet with the owner and had a look. It was just the one room - a combination small kitchen/bedroom/mini-eating area, plus a bathroom and usable balcony - but we thought we could make-do for a season. The grounds were well-groomed and the pool area was pristine and inviting. When we came to discuss price, we told the owner of the offer we'd had only 5 months earlier - 9500 pesos for a large two bedroom unit in the same complex. Although he knew full well we were talking about renting for 5 1/2 months, and that his unit was only a studio, he replied "I usually charge $600 US per week for this one." He said he would think about it and get back to us, but never bothered.
Of interest, while walking the grounds of this same complex, we ran into a fellow who happened to be the treasurer of their condo association. When we told him of the 9500 peso/month offer for a two bedroom, he said we should have grabbed it, that "the owner was basically giving it to you. He's not making any money at those kind of prices." He went on to explain that the annual condo maintenance fee, (presumably for that 2 bedroom unit), was an astounding 60,000 pesos, with a 5 or 10% reduction if paid in full, in advance. This outrageous monthly fee, (back home in expensive Canada, we live in a two bedroom townhouse condo with garage, have nice grounds, a swimming pool, hot tub and clubhouse, and pay half that on a monthly basis) is possibly a result of the problem we've heard of: absentee owners refusing to pay their monthly fees.
A friend and full-time Ixtapa resident says there are plenty of homes for rent there for 6000 - 7000 pesos/month. If so, these folks aren't getting their message out to potential customers.
