@Richard ChangTypically your time frame schedule should be no more than 12 months and depending on your construction finishes, your looking at $200/SF to  $250/SF.Generally you can go to the city's website and pull up Building Permits issues with in the as 12 Months to get a look at the size and valuation in $ dollars of the Duplex's being built.hope this helps.Cheers

I got a letter from the County Public Works Dept. today stating that although my paving contractor applied for permits for our driveway, the pre-installation inspection didn't occur, and therefore, the permits were not issued before the driveway at my property was installed.  

Been through so many of these variables int he area that no obstacle stands in the way any longer, just need to have the proper network in place.Finally, you get what you pay for, always make sure your contractor is pulling permits, do not cut corners, Again, its about building a good team and get references check them out, ask to see portfolios of prior work.

Licensed and insured... are you pulling permits for this work? 

You can also go into some of the less sexy areas(North End, or Mexican Village) buy it and hope the neighborhood starts to turn in 5 years, and in the meantime some of the newcomers to the city get tired of premium rent, leave Midtown stay in Detroit, and land in those areas(two of my tenants have in the last six months).

You also have to add on site construction costs, utilities (if they're not already in place), permits, etc.

This article would seem to agree.Is it possible it was another tax section that permitted you the bonus depreciation specifically on GOZONE real property?

Whether that is permitted in all states, I can't say. 

Let me know if you need permits pulled or if it is a small job. 

Most hired hands are going to burn out fast after they have to chew out a misbehaving sub the third or fourth time.Let me give you an idea from my perspective -We are a design build firm and handle projects including plans, design, permit, material logistics, payroll, book-keeping, ground/assembly management, scheduling, rescheduling, vendor management, quality control/assurance, and every other aspect of construction.We typically have about 5 'ground active' jobs, and 5-7 more in the hopper in some phase of planning, design, or permitting.To accomplish this, we have a meager staff of 2 designers (one of whom is a 20 year architectural veteran), a full time office manager, a full time site manager, a helper who splits time between being a carpenter's assistant and a gopher for materials, and someone who does scheduling and material takeoffs.
