I agree with you there Addie and I think your methodology is flawed J Grant. You have to use a hypothetical condition when developing an opinion of value for something that is contrary to what exists.
Clients esp lenders can require as is appraisals, in fact, URAR Fannie/Freddie will only lend on As Is properties...if the appraiser makes a HC , then the report is subject to the HC and the HC has to be satisfied (removed ) on by satisfying the HC condition on further date inspection or repair to green light the loan.
The small income property appraisal has 3 approaches to value, sales comparison approach ( fee simple) , the income approach ( leased fee / market rents ) and then cost approach if developed, the appraiser reconciles them with no HC. for their as is opinion of market value One can argue the entire appraisal is an HC if one wants to , since there is no actual "sale" as of the effective date, the income approach can use market rents for a vacant property, and no crew is out there building the house on CA.
Since properties sell their fee simple ownership all the time with tenants and leases in place, why does a lease create a HC that does not exist in order to value the fee simple ?
Or do you mean the HC exists to value the fee simple as if vacant (not subject to contract rent ) but vacant with potential for market rent?
