AE fees typically run about 7%-10% of construction cost for commercial work.   

Furthermore, if the building is a new construction they also require payment of transfer taxes as well.  

@Chad Justice,Welcome Chad.You have indeed came to the right place to network,learn, and advance your REI career.When I started many moons ago I too knew some things about construction, trades, remodeling,ect.What I soon found out was that was just the tip of the iceberg.Done correctly REI is about a lot of moving parts.Finance,Law,Marketing,Research,Evaluation are just some of the things you need to educate yourself on toward the strategy you are interested in.

I went through some ill equipped contractors, some dishonest subs who took the money and ran, and stumbled through a 70k full gut not knowing anything about construction while working a full time job.This project took me a year to complete and i learned so much about the business.

I am 59 years old and I have been in the construction business since I was 17 and I had a brokers license for about 30 years but I have only done one investment deal so I do not have the experience you are looking for.  

It has given me hope of making a living part time with my experience, both in real estate and construction and business ownership.

I am 59 years old and I have been in the construction business since I was 17 years old including those years I was in college,  Try to stay within an hour drive.  

When my youngest, Michael, that's now 27 was little we ran our construction/real estate development office at our house. 

It appears that the new construction cannot keep up with increasing demand, causing bidding wars and such making it that much more expensive for new home buyers and investors.
