@Chris Wolf, I'm a structural engineer in the Atlanta, GA area.

I am a working mom of a growing family, my hubby is an engineer and loves is W-2 job so we are somewhat tied to this area and still have our primary residence here.

Costs will vary greatly depending on location, slab and wall specifications, utilities rough in, number of openings, roof structure, site conditions, logistics, labor market, unions, permits, engineering, materials availability and details and level of finish of partitioning to name a few.

Do I need to hire an Engineer or is this something a contractor can easily do without much complication? 

But most flippers in our market go with a middle of the road product, which is often an engineered hardwood.

There are people who specialize in this and basically and engineer does the study.

I am a software engineer that lives in Plano, Texas but I am currently here in Sneads Ferry, North Carolina looking for some multi family and SFH.

Most architects/ engineers will ask for this up front.

There are a few ways to skin this cat, and each consultant (attorney, civil engineer ect) will have their own take on the best solution.

I'm a systems engineer at a managed services provider and work full time.
