Maybe $100/SF is realistic, so we can stick with that number. The simplicity of complexity of design will drive the hard costs. But does that cost include all the costs of site work (clearing, grading, etc) and paving? 30 units on 2 acres will have a lot of concrete, so get a handle on that. And all the utility costs, are those included in that $100/SF?
Also, 21,000 SF is just the total SF of units, but you will have other common spaces (balconies, hallways or corridors, stairs, etc) so again, the design is critical to understanding hard costs. What will the building form what look like?
For soft costs, usually $20-$25/SF is reasonable. You’ll have civil, structural, MEP engineers, in addition to architect. Typically, the developer should be getting paid a fee as well, but that isn’t always the case. There are legal fees, surveys, bookkeeping, permit fees, inspection fees, due diligence costs.
I think 6 months to 80% lease up is unrealistically aggressive. I haven’t done much development, but one of most accurate statements about RE development is that everything takes way longer than you think it should.
Finally, always always include some
OpEx. Even new construction has issues.
