The city must compensate you for taking property so the seller could argue that their silence on this matter caused you no damage.At different apartment complexes, we have twice had the city ask to annex our land, both times to install a sidewalk. 

I’ve seen a number of companies highlight dscr and ground up construction so it would appear these are different products and the ground up development is more private lending.Kevin  ground up development is much more complex.

Or is this an apartment complex with many units in it?

Typically the people who arbitrage properties are operating complex's with 10+ units at a time. 

The more complex you make your LLC situation (particularly with unseasoned proxy LLCs) the less appealing they will be to a lender. 

Complex setups don't offer much protection for most people. 

These two you sent are sold but I will keep my eye on this complex :)

You can exchange tax free into about a $2.8mm class B apartment complex.

I've noticed a lot of confusion and forum posts seeking guidance on 'commercial' mortgage financing for apartment complexes of 5+ unit up to 20-100+ units.

With that information you can then adjust based on your design's location, size, complexity, and finishes, subtract off what you think your materials savings are, and then voila, there's your estimated labor cost.The cost/sf question gets asked all the time on the BP forums so there are already a bunch of responses out there.
