Cookie Cutter, Architect, Engineer Questions

[Joseph Morales]

I purchased a house in 2008. I spent 3 years renovating it by myself. I had it rented out for the past 7 years give or take. I am in the process of selling right now. I am not an expert in the Real Estate game. However, with all that being stated, I've gone through enough of the process to look to become a serious investor. Which is my plan.

Here are my questions:  Why are architect fees so high? Is it like an insurance thing? If they mess up can they be sued for damages?

Is there a standard that can be used in any situation? For instance: If I pay an architect or engineer to design a room addition for a house. Can I take those same plans to my 2nd? 3rd? and so on? If not, Why?
