My architect told me to get a contractor to test if there is lead based paint and get certification or state if they will treat it. but i am gutting the whole interior and i'll be changing the paint either way. is there anything i could do, or you can recommend?

When you're in town @Dylan Whitcher, I definitely recommend Architect Coffee Co.

The only thing to have in mind is that as a foreigner you can not borrow the same amount as residents can (70% vs 80%), the distance and therefore having a strong management set up in place, and the tax consequences from out of the US as (if I am not mistaking) you are always bound to pay your taxes in the US as an American citizen.All other details like contacts (agents, contractors, architects, banks, mortgage brokers, etc) we can help you with as we are active with multiple projects in the Barcelona/Valencia area. 

I agree with @Joe Villeneuve,He's an Architect, and knows his stuff.I also did a mockup for a Class B SFH.Pushed out a wall, cut a doorway, boxed in the water heater (check local building codes re this), added pantry cabinets (at the expense of counter space (not everyone is full on cooking 3 squares a day, with the readiness of microwave and ready to heat oven foods.) 

Hi Robert,The first step in that process is to hire an architect familiar with Chicago building codes and get a print made.

I’m guessing you don’t find most your “engineers, chefs, architects” from Craigslist?

Worked with a great architect in the city.

@Jia Lin You have a tough scenario here but the person you need to talk to first is an architect. 

I would definitely hire an architect to go over the project and I would advise strongly against cutting that corner and trying to figure it all out by yourself. 

Hi Roupnel,A LOCAL Architect who has successfully constructed a multi-family of the size you want (in the last few years) should be able to give you a breakdown of items along with a floor plan and other drawings.Someone with experience in your municipality is best, and be aware of (and ask about) possible cost over runs.Someone with a down-line of subcontractors is a good start.Good Luck!
