When calculating mortgage related obligations under the general ATR rule for a large bank, on a permanent financing loan where the home was recently built and the tax card has not yet been updated to reflect taxes on improvements, what is the requirement for including taxes in the mortgage related obligations for computing debt to income?
Is it sufficient to use what the tax card currently states to compute DTI and for escrow, or are we required to estimate county and city taxes for ATR under Reg Z? If we must estimate is the appraisal ok to use for the estimate?
