lower the size of your unit and therefore your build cost per unit, your sale price will go down but focus on density and get familiar with zoning and what your city will approve. my best suggestion is to do it in downtown districts where there is unlimited height and unlimited floor area and you can build every square inch of the property and reduce parking because of proximity to transit. property values are higher, rents are higher in downtown markets, there are just too many economies of scale compared to suburban deals.
