Also, someone who works with architects

On my first project with these flippers, they acted not only as the designers/architects, but they also pulled permits as “Owner/Builder”.

Review title commitment and survey to make sure to deed restriction and/or HOA in place that would stop you from doing 4 plex2) Meet up with City/County planning office to make sure 4 plex can be build and lot has enough parking spot . 3) Talk to an architect to get an initial foot print, layout and foundation type (i.e. pier beam or post tension slab) 4) Bid out to get estimate for both soft cost (survey + construction drawings + Permit) and hard cost (cost of building)  Without #3 you really cant get hard estimate Problem is that you may not enough time to hash out #2-4.. prior to closing the land .. 

What sort of fees can I expect for the other stuff (architect, engineer, permits, etc)? 

Did you use an architect or draftsman?

I am working on a commercial project in Kansas City and am in need for some architect referrals.

I ask this because I recently saw a small 1500 sq ft 1950's cape bought for $630k and sold for $940k after a very well known architect had his fun with it.

You get this with an architect.

A true cost segregation study requires a qualified construction engineer or architect to perform a site survey, deconstruct the property on paper and reclassify every asset (there are hundreds often thousands of individual assets in a building, even a small rental) which would take 30-40 hours on a small rental and a few hundred hours on most multifamily or commercial properties. 

I need a local architect to draw up plans and a GC who is experienced with these types of loans.
