Let’s talk about choosing comps. I want to share an example of what I did not long ago when there were no recent sales for a unique model in a tract subdivision. Anything to add? I’d love to hear your take.
The situation: The subject property is a larger single story home with a casita. In this case the builder built only a handful of homes with a casita, so comps would be limited. If you aren’t familiar with a casita, it’s a term used to refer to an extra housing unit or detached area. I find it’s often interchanged with “in-law unit” or “accessory dwelling”, but we have to remember an accessory dwelling unit (ADU) actually needs a sleeping area, bathroom, and kitchen to be an ADU. In this case the “casita” only has a bedroom and bathroom, so while it’s tempting to call it an accessory dwelling, it’s really not because there isn’t a kitchen.
The problem: There are zero recent casita sales, so it’s not easy to readily understand what the market is willing to pay for one of these units. What do we compare the casita unit with in today’s market? How do we adjust for it?
What I did: In an ideal world I would’ve had a nearby neighborhood with casita sales, but I didn’t find anything, so I chose to study the neighborhood market by researching three casita sales in the neighborhood over the past ten years. As long as the data was good, I would use research from sales in the past to help me value a property today.
Immediately I noticed the casita sales were clearly commanding a price premium. I thought that this might be the case, but it was still good to confirm instead of assume. Keep in mind if you don’t know how to graph, that’s okay. You can see the same thing when pulling a CMA or printing out sales. Here is a tutorial though in case you want to learn to make a graph like this.
The next thing I did was to research how the casita units compared with other specific models at the time of their sale. Being that most casita homes were somewhere around 2500 sq ft (without the casita), I wanted to see how these units competed with other homes that were around that size. The beauty of having three older sales was I could find what the price adjustment was in each of those situations compared to other specific models. This would prove valuable since I had three recent 2500 sq ft sales without a casita, and I would need to make a value adjustment for the casita in today’s market.
I won’t say exactly what my adjustment was, though maybe I will in the comments.
The big point: Sometimes we have to look back in time to understand how value works. Don’t be afraid to pour through many years of sales to help establish context. Spend time answering the question, “How does a property like this fit into the market?” We can do this by scouring years of sales in the immediate neighborhood, but we might also look to the surrounding market too for competitive locations. Of course just because we research sales that are many years old does not mean we will use them in a current valuation (or a listing presentation for agents). I really don’t have a problem with using older sales when appropriate because we can always make an adjustment depending on how the market has changed over time. But let’s remember FHA wants appraisers to use comps within 12 months, so I probably couldn’t get away with using a sale from three years ago in a lender appraisal. However, I could pull in research from the past to help support the value for what the casita is worth.
I hope this was helpful or interesting.
Questions: Anything else to add? Did I miss something? When have you used older sales to help see the context of value? I’d love to hear your take.

At times it’s not very popular in the real estate community to publicly talk about the market slowing, but it’s something that happens nearly every single year. I realize we have big headlines about the market being “hot”, and it really is in many way, but catching the symptoms of a slowing market is key for valuing properties (and it’s good for clients). I suggest starting to watch price reductions more closely because they’ve been increasing lately in Sacramento and this is one of the first signs of a slowing market. Also pay attention to days on market increasing in coming time along with some of the other factors above (including the sales to list price ratio). I highly recommend asking other real estate professionals the question, “What are you seeing out there?” It’s amazing the type of insight you can glean from title reps, loan officers, appraisers, agents, escrow officers, etc…
Values showed an increase again last month and sales volume was very steady compared to the past few Junes. Overall most price metrics were up 1-2% from last month, though the month prior they increased 2-4%. Inventory is still down about 20% from last year, and properties have been selling like hotcakes in only 9 days (that’s the median). In case you wanted to know, most price metrics are up about 7% from last year. One interesting thing to watch is FHA sales are starting to sag more noticeably as they ticked down a few percentage points to 21% of the market in Sacramento County. Granted, 1 in 5 sales is still quite a bit of FHA volume, but last year we were seeing 1 in 4 sales go FHA. It’s easy to think this means first-time buyers are getting squeezed out by Bay Area buyers, but that’s not really the case. My sense is the downtrend is due to more would-be FHA buyers using competitive conventional products instead of FHA. Lastly, it’s worth noting
