Hey there! Wow, what a horrible experience you are going thru! Well, my family and I are property managers for many families in the Lake Arenal Area, and we have to show bills for everything we get for the houses and properties we take care of, and also we signed a contract for our services every year, on which we establish the monthly fee we will get and all that. We have also done 2 constructions of homes while the owners are away and of course there is a contract with the engineer in charge of the construction. With that contract you can go to the Costa Rican engineer bar and get some answers and directions on what to do and how to solve the problems. In the contracts we have done with the engineers there is the time table of building and also the final price of the construction, I hope you have something similar to this. I can not tell you if what you are paying as salaries is too much because it depends on how big is the property and how many people you have working there. I wish you the best of luck with all this, do not be sad, you will find a solution for your problems, check your contract if you have one and try to solve all this with the contractor or engineer before you take legal actions, anyway the law will be on your side. Again, best of luck!!! Laura Mora, Arenal Lake.
