We've talked about this before, but even with 2-4s the differences in rents between subject and comps can be used to contribution to developing adjustments. If two properties have the same/similar floorplan and unit mix but the condition is different the rents will also usually be different. If one sale has (2) 2bd units and another has 1bd+2bd, the difference in rent between the 1bd and the 2bd can be used to develop that adjustment factor. The GRM for that adjustment will generally be a lot lower than the GRM for the entire property because the latter includes the contributory of the land+improvements, so instead of using the 150x GRM from the sale the adjustment factor might only use a 70x GRM or a 50x GRM. But if the difference in rents is $800/mo x 50x GRM that still amounts to $40,000 for that bedroom. Not $20,000 as might apply to an SFR in that same neighborhood. Cross check with sensitivity analysis between the comps and it will often square up.
