A peer appraiser in my area asked me the question below. I'm curious how other appraisers around the nation approach this issue of remaining economic life for MFH's.
How do you calculate it, especially when there has been NO updating done to the MFH?
"With many of the manufactured homes in our area built in the 1990’s, these homes are now 14-24 years old. Many of these have had little work done to update them, thus their effective age is probably close to their actual age. What do you use for an expectant life of such dwellings?
I’ve seen appraisers use 50 or 60 years, but Marshall and Swift indicates the typical building life of an “average” quality double-wide at just 30 years, and I will go as high as 40 years depending on quality. From what we often see in the real world, that is probably about right.
Such dwellings built in the 1980’s that are close to 30 years old are often found with little or no remaining economic life in them. That being said, those built in the 1990’s may have just 6-16 years of life left in them without major updates, right?
My question/concern on this, is how are sales of these dwellings getting conventional and sometimes FHA financing? FHA requires a minimum remaining economic life of 35 years, which is essentially a brand new manufactured home according to Marshall and Swift."
