I'm not sure if you've ever sold real estate and looked at the listing of improvements and appurtenances that are included in a standard sales agreement. They include such things as: TV antenna and rotor system, garage door opener and transmitter, carpet, lighting fixtures and shades, drapery and curtain hardware, window shades and blinds, screens, storm windows, stationary laundry tubs, water softener unless rented, water heater, incinerators, heating and air conditioning equipment, water pump and pressure tanks, built-in kitchen appliances, awnings, mail boxes, all plantings and fences.
I would suspect that a car hoist that is bolted to the floor of a garage could very well be considered to be part of the real property unless exempted in a purchase agreement if a TV antenna is considered part of the real estate. If not, then all of the things noted above should be excluded from the appraisal of any real estate.
Rather than get into long philosophical and legal discussions on this issue, I'll just say that it has been my policy that if something is permanently affixed to the improvements or the ground, it is considered part of the real property and treated as such.
That's my policy but each appraiser is free to decide for him- or herself where they draw the line.
