After researching quite a bit, I decided that finding architects and a modular build consultancy and arranging the GC myself is probably the way to go.

@Ashley O.I spent some time working for an architect as his sole PM in his design build firm here in Chicago.

Hello everyone,Does anyone have a reference for an architect in Columbus? 

Actors in Hollywood would be a prominent example.

There’s a Plan Reading class followed by a Cost Estimating class taught by an architect m/GC.

Does anyone have any experience with Jonathan Segal's Architect as Developer class?

Would love any tips and/or referrals to reliable GC's, architects and such.

If you built to sell right away, did you have an architect design the home or was a buyer lined up before-hand who designed their home?

Just find an architect who has small multifamily experience, design your three units, and move ahead, forget the other property, you could be waiting and miss the market.My thread outlines the development process on a small project similar to yours from your description.

Also hope this will be useful for those of you who decide against hiring an architect, or those of you who like to keep your architect in check!
