Mr. Rockford,
PE and I never agree, but here I agree with him. So for that sir you have helped us to find common ground, but for you, sad to say, there is something lacking in your training and understanding of the techniques and methodology of appraising to make the comment you did.
I am in disagreement with all of you. In order to do an accurate Cost Approach, it takes as long as writing up a 1004. The M&S version is not an actual CA. It is actually useless for determining Market Value.
M&S does not provide actual costs. Have any of you actually determined actual costs? It is far different than what you get from M&S. When some of you tell me that you do an actual CA using actual costs, then I will respect your opinion on the reasonableness of including these in your reports.
If any of you think that filling out the mutli-page M&S form is a real CA, guess again. All it is, is form filling. You are readiing the M&S manual, looking up the indicated costs and plugging them into a form.
Imagine doing that for the Sales Comparison Approach. Make adjustments according to what some special "Adjustment Book" tells you. I know we joke about the "Adjustment Book" in this forum, but when you use M&S that is actually what you are doing. To be it is laughable, but sad, because that is what many of you think is a real CA.
That is why FNMA stopped requiring the CA. It is actually useless for Market Value. The only entity that actually cares about cost is an insurance company. That is it. If you want to find out the cost of a new build, then why not just ask that actual builder? The home is getting built. Find out how much it cost to build it from the actual contractor? That would be far more reliable than using M&S, and the information is typically available.
What are you going to do?
1) Contractor provided documentation that the cost to build is $110,000.
2) The owner provided three bids for this home ranging from $110,000 to $120,000.
3) M&S states that the cost to build is $95,000.
Are you going to rely on M&S and say that all of the bids and the current contractor have no idea about local costs? Somehow M&S says that it will only cost $95,000, when there is no contract in his right mind that would build the home for that little?
The CA is uselful if it is done correctly (Which it never is in residential appraisal work). It is usefull to determine the cost to build the home. Nothing more, nothing less.
