Two siblings approaching retirement have been weighing for over six months whether to continue living in the single-family home inherited from their parents in Columbia or to move to a condo and sell the house. When comparing the two options side by side, the advantages and disadvantages become quite clear. Considering the costs their parents paid and the current market rates, it became evident that this was not just a matter of sentiment but also a financial issue regarding monthly expenses.

South Carolina is known for having some of the highest air conditioning costs in the country during the summer. The average electric bill in Columbia is $169 per month, while the statewide average for South Carolina during the summer is $194. Although the residential electric rate in Columbia is 16 cents per kilowatt-hour, which is 21% lower than the national average, residents consume about 13,000 kilowatt-hours annually, which is 15% more than the national average, negating any relief from lower rates. Research indicates that switching to a high-efficiency heat pump can reduce cooling costs by 30% to 40%. While the percentage of summer electric bills relative to household income decreased from 3.8% in 2020 to 3.2% in 2025, it still remains relatively high compared to other southern regions.

The single-family home where their parents lived has a large area that needs cooling, and ongoing maintenance for the roof and yard is required. This is certainly a burden. On the other hand, moving to a condo would reduce the cooling area, and external maintenance would be handled by the HOA, or homeowners association. However, they would need to pay monthly maintenance fees, and the indoor space would be smaller compared to a single-family home.

The median home price in Columbia is $265,000 as of July 2026, while the median price for condos is $153,900, significantly lower than single-family homes. Looking at HOA fees, the median for condos is $363 per month, while townhomes average $136 per month, and the overall average for listings is around $66 per month. In South Carolina, the median HOA fee can rise to $410, indicating that even within the same condo, management fees can vary significantly depending on the community, which presents both advantages and disadvantages. There are also Active Adult Communities for those aged 55 and older located on the outskirts of Columbia, which offer convenience but typically have higher initial entry fees and HOA costs than regular condos, so a generous budget is advisable.

The effective property tax rate in Richland County, where Columbia is located, is relatively low at 0.72%. Additionally, homeowners aged 65 and older can apply for the Homestead Exemption, which completely exempts property taxes on the first $50,000 of the fair market value of their primary residence, and Richland County also offers additional reductions for those over 65. The tax assessment ratio for owner-occupied homes is 4%, which is lower than the 6% applied to rental or vacation properties, which is another favorable aspect. However, these exemption criteria can vary by county, so it is recommended to check directly with the Richland County assessor's office. While Columbia offers favorable property tax conditions, when considering the burden of cooling costs, it becomes clear that the advantages and disadvantages do not lean entirely in one direction.

• Single-Family Home - Spacious but ongoing costs for cooling, yard, and roof maintenance.
• Townhome - Reduced management burden but monthly HOA fees and significant community variation.
• Condo - Lowest price and management burden but smaller indoor space.
• Active Adult Community - High convenience and management ease but increased cost burden.

Ultimately, the siblings decided to keep the single-family home but to replace the cooling system with a heat pump as a compromise. Both options have clear pros and cons, and the best choice will depend on each person's management capacity and budget.
