Construction management, property management, various sales careers which will be commission based.

I have been involved in the past about sales managing and maintaining commercial properties as well as construction projects into retail, banking, movie theaters, and a hotel.For about a year I have been watching and listening to a gentleman that has about 25 years in the experiencing of successful real estate buying and selling apartment complexes and currently owns almost 5,000 apartment units. 

Is there a lot of benefits in integrating a construction company into a real estate company?

You can find they will lend 85-90% of purchase, and 100% of the construction with most programs charging 10-12% interest with 2-3 points.

Also, how can you strereo type me and my ability to construct a deal simply because it’s my first REI deal.

If you are buying new construction without an Agent, you most likely will be using the Builder's Lender, as most Builder's "incentivize" the transaction as such it's difficult to use another Lender.

The initial charge for the construction documents is $10K.

Being in the construction business for about 30 years and having a real estate broker license in Texas for about 30 years gives me a unique answer probably regarding your issue. 

Ended up switching to a new property management company that also has a construction arm of their company.  

My research leads me to believe that a specific mortar needs to be used, as the stone and antique brick are not as strong as modern day products/construction.
