Hi Leo,Those on your list are all renovation components that are very difficult for non-professional contractors/engineers to inspect and estimate. 

Do I really see myself having an engineering career? 

@Scott Wolf I am an Engineer, just have plans of relocating in the near future. 

With that said, the best, easiest option for you is to take it to a civil engineering company to subdivide the property such that it meets local zoning requirements and to figure out how to protect the wetlands. 

After several hours, a very nice, early 60's engineer responded.

I will also check with the code enforcement in my local area to see any engineers listing and check prices. 

I am a civil engineer looking to move from Westchester, NY to Fort Lauderlade, FL.

I found Google Earth Engine not to long ago.

Now that I've graduated with a good job lined up I'm finally ready to take the first steps in beginning a new journey in buy and hold real estate.I'm currently living in the Tualatin/Tigard area and working as a mechanical engineer for a large semiconductor firm.

However, this home is in Berkeley and I am concerned about destroying historical elements and potential added structural engineering costs that could make the house attractive to a buyer in future years, along with the opportunity cost of construction now versus getting rental income from the house in the next few months.
