So... for those of you like me that appraise all day long... every day... 24/7/365
What % of concessions do you typically adjust for?
100% for entry level homes?
50% for jumbo estates?
Thanks or the info!
It depends on the price tier, the market conditions, the typical buyer for the properties in question (buyer demographics).
Sometimes my adjustments are $4$, sometime they range from $1.50-$3 for every $1 of concession. In my experience, they can be less than $4$ but seldom are.
Lee has it exactly right. This business is rife with unbridled ignorance of the concepts involved for the contributory values of this feature. Worse yet, the same concepts govern most other adjustments one must make, suggesting that many practitioners are just winging it when it comes to many adjustments.
Let's review some of the ways one can determine or support the adjustments:
You can ask the: broker, listing agent, selling agent, buyer or seller. The down side here is that they may not know. They may think they know, but the actual contributory value can be higher. I've found that RE operators with skin in the game, such as rehab investors often have the best handle in certain markets as to what contributory values such concessions return. In some markets the deals won't take place if concessions aren't offered. Those are the one in which the concessions often contribute at multiples of $4$.
You can apply the cost method. $4$ is very attractive logic as many of the posts in this thread will attest. As with much else, however, it sometimes isn't true and needs to be tested. Have you ever seen $2k in landscape labor & expense add $5k to the value of a house? I have. Same with concessions. Some buyers are so cash starved that they would gladly pay higher than $4$ to save cash for all the expense that will take place after closing. Besides, if they can add that contributory margin to the loan balance, it's easy enough to justify. For Sellers, the logic of it says that any seller that makes a $1 concession to receive a return of less than $1 is a moron. IME, that's probably about right but we have to admit that even morons trade in real estate.
You can perform a paired sale analysis. Good luck with that. The right circumstances for this method almost always seem to happen by chance, and often when you're not really looking for them. But when you come across them, pay attention. Such occasions can help you refine your adjustments for a whole host of issues.
You can perform a trend analysis, that is, adjust your comps to the subject for everything else except concessions and note the differences among the comps which have and do not have such concessions. Overtime this will give you a feel. Like paired sales, doing this just once or twice won't help you much. You have to do it often and over time to refine all your adjustments.
Lastly, there are several other methods that, IME, many appraisers, maybe even most, seem to employ:
1) Magic Eight ball
2) Dart Board
3) This is how I was taught.
4) Guess
5) Peer Survey.
Peer survey is the method employed by the OP in this thread. There is nothing wrong, per se, with peer survey if the group from which answers are obtained happen to know what they're doing. But so many appraisers rely on methods 3 or 4 that this method can acquire the same level of reliability as those other methods.
