So multiple eyes and local expert providing local cost and input on lifespan.Here is an example that has a part that is more expensive in my market than other markets (unlike most parts that are the same everywhere, so in this case your cost should be significantly less due to both cheaper part and cheaper labor): $1600 40 gal water heater installed (this is good price for a plumber, a little high for a handyman) with expected life of 12 years (i have some that go 20 years and some that die in less that 10 years (mostly rheem die in less than 10 years), 12 years is fair life expectation

Example: If a business buys an oven and it costs $5,000, and $1,000 for installation and setup, and $200 of delivery and transport fee.

The agreement is contingent upon the buyer securing financing which I was not able to do and have provided a denial letter.The seller is requesting money for damages because the appraisal came in at the purchase price but needed a heat installed in the kitchen which the seller agreed to install (Not in writing).

In the manufactured home industry, I've heard more complaints about new homes being bought and installed straight from the factory than consumers buying older homes direct from homeowners. 

Up north the gas company will install additional meters for a very low cost, usually hourly billed time for the work and possibly low cost equipment.
