Has Yavapai continued the info in the legal description? Department of Revenue had a former employee from Maricopa County assessor's office for awhile that got very confused regarding that 1912 law (because Maricopa has been confused since 1980). The change to that specific law that went into effect in 2000 only changed the scheduling of the personal property roll to once a year and could be paid in two installments. Before that the personal property roll came out each month, a homeowner never knew when to expect the bill, and it was due in full within 30 days (called unsecured). The requirement still remained that if there was real property of at least $200 in the county owned by the owner of personal property, any personal property had to be listed with the real property (called secured). That is why in 1980, Graham and Yavapai started listing all the info on all the manufactured and mobile homes on a parcel, whether an Affidavit of Affixture had been recorded or not. Other counties started following suit, Maricopa refused. Then about six years ago the uninformed person at DOR got a batch of the new assessors that were not familiar with the 1912 law confused and they stopped listing the info in the legal description. I helped develop the Affidavit of Affixture back in the 1970s, when the HUD building code went into effect in 1976, manufactured homes became able to obtain 30 year loans just like a house--and that was the purpose of the laws regarding Affidavits of Affixture so that the unit could be taxed as real property. Before 1976, mobile homes could only get 10-15 year loans with a very high rate of interest no matter how they were taxed.
I cover everything that is within the expertise of an appraiser in one paragraph in my addendum. If the client has a hissy fit, I fill out one I have created with wording exactly from Fannie Mae. If they threaten me with bodily harm that I have to use theirs, I type after most of the sentences that what they are asking is not within the expertise of an appraiser and a licensed appropriate individual needs to be contacted if they have a concern, that I observed the property for valuation purposes only and I am not a licensed engineer or contractor or home inspector.
Kyle: If you cannot find anything on or inside the home, talk to the homeowner. Ask to look at their ownership documents. If they haven't done whatever procedures is needed in your locality to enable the home to be taxed as real property, they will have to provide those documents to the lender and complete those procedures before the loan can close. In the ownership documents should be the year, make and serial number for the unit(s). If the procedure has already been completed, then the assessment office should have the information, there might even be recorded documents with the info (what state are you in--Arizona has a very good system). The homeowner has to have some proof of ownership, somehow, somewhere--or how are they going to be able to encumber the property with a mortgage? Assessment offices, building departments, zoning departments and other local government offices should also have some info somewhere. You might have to become a detective. Or call the lender, their title company or real estate attorney (depending on your area) should have been the detective of the ownership documents for the lender. If you cannot find info anywhere, then tell the lender you cannot complete the appraisal until they provide you with the information from the title search. And no they can't get a 24 hour turn around on this order!
