Any office that doesn't have this information goes for cost of equipment, which is basically probably a loss to the owner.

To prepare for maximizing bonus depreciation or conducting a cost segregation study, you can begin gathering detailed records of the property's assets and improvements, coordinate with a cost segregation specialist early, and consider any renovations or purchases of eligible equipment to align with tax strategies that take full advantage of the current bonus depreciation rates before they phase out.

Very dependent on each home's usage profile (as you mentioned) along with heating/cooling equipment type, utility rates and and solar net metering schemas.

The companies that provide the equipment and split the income are called Route Operators.

When we opened our tent and event rental business (with a small out of pocket cash investment in equipment), my wife asked for a business plan. 

The extra $43’000 will go into transport of the equipment as well as building an enclosure for it.

If you do nothing it will make them more available and better equipped to scam the next person.
