When you pull the permit to replace that old water heater, are you going to learn that your county has a minimum standards requirement in place so that once you pull ANY permit - ALL your major systems - electrical, plumbing, gas lines, HVAC, venting, flood and fireproofing, etc - must now come up to code?

Water/ Sewer/ Gas are all on the street.  

I have several ballpark quotes from two different contractors.Replace steam boilers: ~$4000 per unitNew gas boiler and forced hot water system: ~$12,000 per unitNew gas furnace and forced hot air system: ~$12,000 per unitIn your experience, would it be worth it to replace the entire steam system with one of the gas options?

For example I know most properties a few blocks from college, or close to a military base are solid indicators if the numbers work, but what else.All major operations use some type of model that's a lot more complex, for example, Walmart or Sheetz gas station have some type of population and traffic to housing location model that works.Thanks in advanced.

Yes does have furnace gas i believe sounds like it hasn't been run in a while. ( I figure new hvac) That's for the follow up to all.

Though his explanation makes sense to me about being a lien holder..similar to a gas or electric company putting a lien on a house, it's not considered a transfer taxable event for them.
