One of the properties we manage has an available (just finished) 3rd floor, two bedroom, one bath unit, new construction located on Fire Coral Street, San Pablo area, about 1.5 miles south of town center. Not furnished, fridge/stove only and no pool but private balcony and good views of lagoon and sunsets! Owner asking $750 US/mth. This may give you an idea of local market rents.
On the beach, furnished with pool, may be very difficult to get for $900 US/mth??
