4419 49th St; 3bd/1ba. 1200sf on 3800sf lot, inferior condition, no onsite parking or access; listed for $525k on 05/05/2022 so it wouldn't show in an appraisal but it can be related to the subject's actual value as of 04/2022. Add for lot area, GLA and the interior condition.
And I love this one because it indicates to the land values:
4832 S Graham St; 4bd/3ba 1480sf, similar if not a little superior in condition, driveway. Listed for $650k in 02/2022, but sold for (wait for it) $925k in 03/2022. EXCEPT that sale also includes the adjacent vacant lot of at least 6000 sf. So that right there indicates to the lot value of $350k for 6,000sf.
There's more, but I won't bore you with them. The point is that the subject's condition and lack of parking/access can be matched or bracketed in this area without the use of the big remodels. And that range of unadjusted pricing doesn't come anywhere close to implying the original $670k value was grossly out of line for a C4, 1ba, no offstreet parking, needs new-roof-soon property.
Nor is there any call for relying primarily on 2021 sales in this appraisal, either.
