I recently had the opportunity to speak with some great local real estate agents about a wide range of topics. We discussed appraisals, market value, and many other issues related to the overall housing market. The hour and a half flew by and although we covered many topics, there were many more we didn’t have a chance to discuss. One of these topics was a question about whether appraisers consider different heating fuels and what affect they may have on value.
It’s a great question and I finally had a chance to dive into some data, but first I want to make it very clear that my opinions here and the data discussed in this post are relevant to my market (Massachusetts) and may not reflect conditions in other parts of the country. When it comes to the costs and market reaction of different heating fuels, so much depends on the local market and the conditions which exist within it. With that said, let’s get into it.
Price Volatility
I wanted to start by seeing how each of the primary fuel sources have varied over the years. The most common fuels in this area are oil, natural gas a electricity (no offense, propane). I created the charts below from data I compiled from the most reliable sources I could find, but please keep in mind that I can’t guarantee absolute accuracy. When possible I used reported prices as of January of each respective year in an effort to create a reliable comparison. Let’s start by looking at all three heating options and how price trends have changed since 2000.
The scale in this chart creates a slightly misleading trend for oil prices, however we can see that prices for all fuel sources vary over time and there are a variety of reasons for this. General economic conditions, geopolitical factors, foreign events, political and/or social agendas, and other unexpected events such as the global pandemic can all influence the price of heating fuels to varying degrees. Due to the myriad of factors which affect fuel prices it can be very difficult to predict where each will be one, five, or ten years from now.
When I started my appraisal career in 2002 we typically made a negative adjustment for electric heat because it was generally viewed as the most expensive option. Then the war in Iraq and Afghanistan led to wild volatility in oil and gas prices; if you weren’t in the real estate biz then, or if you’re not old enough to remember what was going on at that time, check out the charts below and look at gas and oil prices from 2002 until about 2006/2008. At that time, the price of a barrel of oil dominated the news and homeowners felt the economic impact which began to influence buying decisions in the housing market.
From 2002 to 2006, the price of natural gas rose approximately 96%. This was followed by a decade of declining prices, then some stability for a few years, and then a sharp increase over the past few years.
Similar to natural gas price, the cost of oil increased steadily beginning in 2002. However, unlike gas prices, the cost of home heating oil continued to soar through 2014 before finally receding and stabilizing for about 7 years, and then jumping again from 2021 until the present.
During the early years of the Iraq and Afghanistan war appraisers started questioning whether the longstanding aversion to electric heat was still really impacting buyers’ decisions. Locally, from 2002 to 2006 prices for each of these heating sources had increased:
Natural Gas +96%
Oil +106%
Electricity +45%
Suddenly we found that many buyers didn’t want the volatility of gas and oil but instead preferred the relative stability of electricity rates. It was all going up, of course, but it made sense because buying a home requires adherence to a monthly budget, and uncertainty over the heating bill could lead to difficult financial and lifestyle decisions.
While electricity rates rarely decline, we can clearly see that prices for this option are far less volatile than gas and oil. It would be reasonable to assume that prospective home buyers, when preparing to make such a significant purchase, would prefer a more predictable home heating expense to have confidence in their financial budgeting plans.
Does It Affect Value?
So this all leads to the point of this post about whether home heating fuel influences market value. As I discussed above, there was a palpable sentiment among buyers in years past about having an aversion to electric heat due to the clear and rather significant higher cost compared to gas and oil. Even still, there were times when agents and homeowners would express an aversion to oil because of the perception of it being a ‘dirty’ fuel, or the desire to use a more sustainable and environmentally-friendly heating source. Others expressed concerns over the safety of heating with natural gas. Whether real or perceived, some had concerns regarding carbon monoxide poisoning or the combustible nature of natural gas. Here in Massachusetts those fears were exacerbated in 2018 when a series of gas pipeline explosions leveled dozens of homes, injured several people, and even resulted in one death.
The bottom line here is that as appraisers we must know the market areas in which we work, and use market data to drive our value conclusions. While it was apparent that most buyers were less willing to purchase a home with electric heat up until the early 2000’s, changes in the energy industry, social narrative, and political climate have blurred the lines between cost and value of heating fuels. Government intervention also plays a role as laws and regulations of those in power influence the cost of producing specific fuels while incentivizing or subsidizing others. There are many who feel compelled to use alternate, sustainable energy sources, and yet others who would argue that producing more wind and solar power, or a move away from fossil fuels to an electric world, is counter-productive due to the materials needed to produce those alternate energy sources and the concerns over relying on foreign nations to provide the materials and technology needed for the transition.
All of these complexities have led me to develop a professional opinion that, in my market, heating fuels are a personal preference by each buyer. It has become more equivalent to paint color or style choices in which some buyers prefer white cabinets and natural gas heat, while others prefer hardwood flooring and electric heat. In some cases a preference may depend on specific location or trends within a specific neighborhood or community.
For example, a neighborhood may be developed with a focus on limited environmental impact which may include utilizing renewable energy sources such as solar panels, home designs which comply with LEED certification standards, and even site designs and home placement which take advantage of passive solar heating. In these cases, typical buyers of homes in that area may be willing to pay a higher price for homes which meet their specific preferences centered around environmental concerns. In other areas, buyers may prefer natural gas because it’s responsibly produced, readily available, reliable and clean-burning.
This issue can be complicated but buyers and sellers will often provide these answers for us by their actions. As a general rule, however, I cannot say with confidence that any specific home heating fuel in my area universally has an influence on market value. And in our current market, which continues to demonstrate historic inventory shortages, buyers tend to be more tolerant of the things about which they may otherwise value more positively or negatively, simply because the options are so limited. I would suggest that the most reliable conclusions in this type of market can be drawn from trends in new construction where the buyer gets to choose the heating system and fuel, however it should be noted that some options are not available in all locations.
