What helps us answer quickly

  • The Idaho county you are buying in, since it sets the conforming limit.
  • The departing home's full payment, including taxes, insurance and any association dues.
  • Its assessed value, so we can estimate the tax line after the homeowner's exemption comes off.
  • Whether the departing home is listed, under contract, or neither.

What happens next

Our team reviews it and reaches out shortly. We will tell you which of the three structures fits, what the departing home does to your ratio once its exemption is gone, and what reserves to expect. If the answer is that you should wait, that is what we will tell you.

Before you call, the structures page and the Idaho guide cover most of the ground. The tax question is on the exemption page.
