Would love to connect with an architect as well.  

Any recommendations for a general contractor, structural engineer, and/or architect in the East Bay?

If not, how can I find an architect who can accomplish this?

So I spoke with an architect and he said to factor in around $250 per sqft for construction alone. 

An engineer/architect will need to decide if the foundation and first floor framing are sufficient to hold the weight from an additional floor above.A good general contractor will be able to take care of all of this for you from initial planning to full execution.

My suggestion is to find a really good architect in your area and he might be able to guide you through the process.

I just spoke with an architect and found out the construction costs are going to be around $250 per sqft. 

Hey guys, I recently discovered the Homestyle loan which allows for purchase+rehab of property on one loan through Mark Ferguson on youtube.However, in order to get a homestyle loan you need full plans from an architect or GC for the appraiser to see the ARV.

I’m an architect and investor in the area.

But for construction, especially MF, you will need cash for all the soft costs, which are permits, architect/engineering fees, utility hook ups, etc.
