In my 14 years in the biz, I’ve been in about 15 deals where buyers had them done and only once has it come back as “elevated”(barely above the minimum threshold It was my listing, a garden unit in lake view.

Is there software that I can simply feed the size of the units I am looking to build inside the 8000 sq ft footprint and the software can determine best layout (accounting for elevator etc?)

I have dealt with quite a few and sometimes some have a way of elevating their interest of earning a commission above the clients best interest.

I've done many of these, but you're going to have to have an elevation difference somehow. 

I'm looking at a brick 3-Flat in Chicago that is immediately next to the elevated train line.

My plan is to spend between $20-$30 per foot to remediate all that damage and bring it up to Class B+ (there is no elevator).

Lower-end houses you may see too thin margins or elevated risk and higher-end houses your profit margins will end up considerably higher than your competitors and you'll likely close fewer deals.- This assumes that your financing costs aren't tremendously high, as they sometimes are with hard money lenders.- This assumes your happy with about 12-18% ROI on your invested capital (for an all-cash deal).In my opinion, there are better ways to evaluate a deal. 

Also not sure of where you are geographically but in colder winter states they add electric reheat backup which elevates the price.

Specifically, here is the info I am looking for:Average cost of land or propertyCost of land or property as it relates to per square foot of buildingCost of construction per square foot (including elevators)Cost of elevators (itemized separately)Average rent per square foot per yearCurrent rates on construction financing for office buildingsThanks for all the help, guys.

The top of the lowest part of the foundation must be 1 foot above the flood plain, if you house is in a flood plain but built on a mound or hill, a "spot elevation" by a surveyor is worth the engineer's assessment.
