How do I calculate the cost basis for the "new asset" (one unit)?
For example, if the entire fourplex cost me 500k, with land being 100k and building 400k, I basically had 300k as my cost basis for the 3 units (75%). But that was two years ago.
What would be the cost basis for this one unit now? Would it be the 100k (25% of the 400k from 2 years ago)?
