The following are some opinions that are good today. Tomorrow they might not be.
The cost approach on page 3 of the URAR is economic life, which is different from effective age. Many appraisers I have discussed this with tend to treat remaining economic life and effect age as part of the same theory. I think that is probably wrong.
Fannie Mae (whose guidelines we follow with the URAR) wants effective age to reflect the physical condition of the property.
Section 404.02 - Actual and Effective Ages
The relationship between the actual and effective ages of the
property is a good indication of its condition. A property that has been
well maintained will generally have an effective age somewhat lower
than its actual age. On the other hand, properties that have an
effective age higher than their actual age probably have not been well
maintained or may have a particular physical problem. In such cases,
the lender must pay particular attention to the condition of the subject
property in its review of the appraisal.
Therefore, when completing a residential URAR report they are part of the same theory. Total economic life (TEL) is the expected term a house would maintain a value without any improvements made. Effective age (EA) is how much of that time that has expired factoring in improvements, updating, etc. Remaining economic life (REL) is the total economic life less the effective age. If TEL = 60 and EA = 20 than REL is 40.
Where did economic life come from? Especially the idea that the original economic life should be 60 years or any particular number of years. Original economic life has two factors: 1)Quality of construction 2)External influences.
On the URAR external influences do not play a role, they are accounted for separately. Total economic life is based on expected physical life of an improvement should no further improvements be made, and it comes from the market. There is a way you can determine it from your desk when you have comps that have never been updated and they are younger. If you want to know drop me a private message. But on page E-7 in the Marshall and Swift, the book appraisers have traditionally relied on for the cost approach, there is a table for TEL based on their market studies nationwide. Average quality average condition is 60 for concrete block and 55 for frame housing. You can argue with it, but at least it is something to fall back on.
A well built house without any negative exteranl influences should have an infinite original economic life. About 15 years ago I appraised a house built in 1890. Said house had been completely gutted and everything except the wood timbers, planks, and the foundation(Bricks) had been replaced or new and current equipment and built ins had been installed. All of the remodeling had been done within the previous 24 months. The only negative was a freone had been allowed to get on the wood exterior behind the AC unit and the paint was not sticking like it should.
Economic life, the way we use it for the cost approach, is a component used to measure physical depreciation not external inadequacies. We factor external depreciation and functional obsolescence on their own.
Example: A brand new two story brick veneer home was built a couple of years ago in Clevealnd, Texas in a block, on a street that has all vacant lots going commercial. The exterior observation of the dwelling indicates it would be difficult to convert the floor plan to commercial without major reconstruction. IMO the original economic life of the structure could be zero as the structure's H&B use is in serious conflict witht he H&B use of the raw land.
The TEL (how long a typical improvement like it is anticipated to contribute value to a property without making improvements) would likely be 60. Remember, TEL comes from the market, not from the subject itself. The effective age of the subject (when effective age is viewed from an AI definition), on the other hand, might be 58 because economic/external influences caught up to it quickly. The AI tells us that all form of depreciation should be built into the effective age (functional and economic). But in a residential report we have traditionally parsed our types of depreciation to express which is what and why. So your new house may have a TEL of 60, an EA of 0 and its economic depreciation as measured in the URAR might be the entire cost to build plus cost to demolish.
At the risk of being verbose, but for full disclosure, let me point out that Fannie Guidelines do not require a total economic life estimate or estimated remaining life estimate. Only the estimate of effective age. So what you do is not "wrong" but perhaps just a little unorthodox. That's good, it shows you are thinking about appraising and not just filling in forms. But those who do it the other way are not incorrect either and I am merely trying to explain, not influence.
IMO effectife age should be the actual age adjusted for maitenance and updating or remodeling.
A 10 year old house with the original composition roof can not have the same effectife age as the identical 10 year old house next door that has just had it's composition roof replaced.
IMO both houses should be considered to have an effective age of 10 years. One should have a condition adjustment for the older roof.
IMO condition has limited or no effect on effective age until condition nears or reaches the point that the house is not livable.
I agree with several who pointed out that effective age is frequently used to tweak the appraised value.
Someone please tell me how a house of any age over 30 years can have an effective age of 25 years and remain livable. How can a 5 year old house have an effective age of 3 years? I have seen and/or heard both comments. Sounds like tweaking to me.
TEL measures how long a structure is expected to contribute value if no improvements are made. Effective age is the age of the house relative to its improvements made. So a 10 year old house that has never been updated at all and has a 10 year effective age and sells as a market sale for $100,000 has, for arguments sake, 50 years remaining in economic life. It suffers 20% depreciation and its improvements cost $70,000 to build. Now we appraise a the identical house, same condition but it has a roof and, having great comps, it comes in a $105,000. Its effective age would be 8. On the first house the dwelling sold for $100K, Bldg was worth 70K less 20% depreciation so our land value is $44,000. On our subject the land value is the same so the building contributes $61,000, which is 87% more or less of the cost to build new. Our problem becomes 60 divded by X = .13? And our answer is 60 X .13 = 7.8 or 8 rounded.
As described in the 1890 era house above. Remodeling or updating as some call it can theoretically eliminate any amount of age.
You can eliminate a lot but the only way to eliminate it all is to knock it down and start over.
I agree with one of the earlier posters, please advise how to derive effective age from the market. I think the remaining economic life can be drived from the market as in the new house in Cleveland I described above. IMO that new house could probably be proved to have no remaining economic life at it's inception.
I think I showed this in your 10 year old comp example.
Another variation is two houses side by side that were built 60 years ago. One has been remodeled/updated with everything new except timbers, planks, and foundation two years ago but has been poorly maintained since the remodel. IMO effective age would be 10 or less. I just don't like going below 10??? Condition would be poor and require a large adjustment.
The other has never been remodeled/updated but has received exceptionaly maintenance throughout it's life. IMO effectove age could be well above 10 years and require an adjustment but condition would bed average and require no adjustment.
Maybe. As appraisers some believe we should take ourselves out of the equation and let the market speak, not our opinions. Others like to claim they are being paid for their opinion, so that is all that matters. I go with the first group and so, for me, effective age is not any different. You have to let the market tell you the effective age, not your hunch. To a gut appraiser, effective age adjustments are fudging. In practice, when I see a gut appraiser's report making effective age adjustments (and you can tell the difference between a gut guy and a facts/market analysis appraiser) I not only think they are fudging, but I think they think they are fudging it but that it is okay because it leads to their final, gut driven, opinion of value. (BTW, I don't make effective age adjustments, just condition and actual age adjustments).
This last comparison is extreme but is being used to attempt to point out the difference IMO between effective age and condition.
The URAR says actual age. IMO that requires an analysis of any remodeling/updateing with a resulting adjustment. However, to do that properly the appraiser would have to do the same analysis of the sales used as comparables.
I base my determination of effective age of the comparable sales on observation from the street, conversations with realtors, conversations with anyone else who will discuss the issue, and my own experiences in the area. This part of the competency requirement.
Now that I have gone completely in a circle please comment.<><
Age is an actual, straight, factual number. To me, it measures incurable types of depreciation. A 7 year old house has 7 year old appliances that might need replacing in 3 to 5 years and a roof that might need to be replaced in 8 to 13 as opposed to a 2 year old house all other things equal will likely have different values. But more than likely it wouldn't be practical to replace the roof or appliances in the 7 year old house now, so the depreciation is incurable and, from my perspective, in adjusted for in the actual age. Roof rafters, foundation, slabs, timbers in a structure, etc., are also incurable.
Condition on the other hand, for me, reflects curable types of depreciation. You have two 1890 houses but one has been fully updated and the other is not. As long as I have comparables that have been updated and not updated, I can extract a market reaction for the condition and make an adjustment without relying on an actual effective age number.
