Proper valuation of unfinished new construction

[Klemont Wright]

Hi all.

We have a couple opportunities ti purchase a couple properties (one is a single family, the other is a duplex)

Both of them are new construction but only about halfway complete.

We have learned of the reasons why they were not finished.

My question is how do we properly gather value on these properties?

Do we value them according to “completed” comps as we normally would as part of the formula, and apply a “% complete” (ie, 50% complete) split?

Obviously, considering our construction completion cost, but does this make sense to arrive at current value for our purchase price consideration?

How have you guys approached this situation?
