I am having a discussion with an underwriter as to the appropriate adjustments necessary when appraising a fourplex.
The underwriter is of the opinion that adjustments for baths, square footage, location etc are necessary ....
In my opinion ... these items are considered in an income adjustment. Where comparison of the subject rent is made against that of the comparable and the resulting difference is then multiplied by the comparable GRM in order to arrive at an adjustment for that sale.
One adjustment considering all other differences.
How do the rest of you make adjustments when appraising a four plex within the market grid??
PE-
I'm not sure I fully follow you, so let me try to regurgitate it:
Income (rents) should reflect the differences in user (renter) appeal for the items you mention (bed/bath, GBA, etc.). Assuming GRMs are similar, the one with the best appeal to a renter is going to have the higher rent and therefore the higher value. So far so good.
Sales comparison approach attempts to do the same thing, but rather than doing it the easy way (as was done in the income approach since all differences are assumed to be reflected in rents), we now need to try to identify those units of comparison that best reflect buyer/seller valuations. So, why it makes intuitive sense that a buyer will pay more for additional GBA (up to a point) because they should be able to get a higher rental rate, how much further "digging down" one must go to break-out the incremental value (to the buyer) an additional fireplace or half-bath adds? When does the GBA difference include the bedroom or the bath difference. Is there really a location difference warranted on a rental unit? And, the problem becomes more difficult if there is dissimilarity among the sales comparables.
The problem (IMO) is that while the UW may think there are two different approaches to value, there isn't. Income is what is being valued in both approaches. The IA makes it easy because all components have been reduced to rent. The SCA is not so easy because some (the UW in this case) thinks that it is possible to extract the value contribution of a bedroom based on some other mechanism when the value contribution of a bedroom is presumably the additional rent it generates.
So, what I try to do is this: Reduce my grid adjustments into three general categories:
A. Size differences in the rentable area, typically expressed as a GBA adjustment.
B. Condition adjustment- and more weight given to maintenance level items then upgrades (depending on the market, of course); sometimes a remodeled unit is not going to generate a significantly greater amount of rent. But roof that is at the end of its economic life must be replaced.
C. Location adjustment. This is the most subjective of them all, but can be supported by rent differences. What may be an impairment for a SFR may not be an influence on a rental unit. But, if there is one nice area of the neighborhood where the difference is due to the location, so be it (I don't see that a lot).
IMO, these three adjustments reduce the SCA problem to something that is manageable.
We are making GBA adjustments for differences in GBA which assumably affects rents. Yes, if you have units with significantly different bed/bath counts, that has to be analyzed. In many of my markets, the difference in bedrooms can be accounted for appropriately in a GBA adjustment.
Condition adjustments reflect differences that buyers will consider. Again, if I'm buying a property that needs to be repaired or upgraded, that may have a secondary impact on rents but will have an impact on my purchase price- I will not want to pay the same for two properties even if their rents are identical if I know I'm going to have to spend out-of-pocket monies to fix one of them that I wouldn't have to spend to fix the other.
Location adjustments. Rarely do I find them necessary, but if a property is located in what appears to be a nicer neighborhood and the rents are higher for no other reason, then a location adjustment is necessary. If no discernible difference in rents, no location adjustment despite what may appear to be superior or inferior- the market simply does not recognize it.
This takes a little set-up in the addendum explaining why I chose these areas as the units of comparison and adjustment in the sales grid. And, of course, it assumes that the dynamics of value can be categorized as I outlined (not always possible, but I find it so in my urban and suburban markets). It also assumes that we are talking about properties that trade based on their investment appeal vs. owner-occupied (which skews everything!).
My experience is that with some UWs, they expect to see adjustments for certain differences whether such adjustments are warranted or not. OK, fine

. My process is to tell them where I've put that adjustment (GBA, condition or location) so to give them a level of comfort that what they think is necessary is included in the report (and if it is necessary, it is included in the adjustment!). :icon_wink:
