The effective property tax rate in Suffolk County is 0.66 percent, which is lower than the Massachusetts state average of 1.11 percent (propertytaxrates.org, based on 2026). The residential property tax rate in Boston is about $10.58 per $1,000 of assessed value, and there is an exemption that saves owner-occupants approximately $3,500 annually (boston.gov). The same tax rate applies to both new and existing properties, but the actual burden can vary if the assessed values differ.

The supply trend is clear. In the first quarter of 2026, the number of new construction permits in Boston was 432, down from 549 the previous year and 642 the year before that (centrerealtygroup.com). This is the slowest construction pace since 2010. What this number indicates is that new listings are becoming increasingly scarce.

Nevertheless, areas like Seaport, South Boston, and East Boston continue to see a steady supply of new apartments (centrerealtygroup.com). In neighborhoods like Brighton, 1-2 bedroom condos are trading between $500,000 and $775,000, with a trend showing that newer constructions command a premium (sellinboston.com).

Choosing a new condo often means lower heating and cooling costs due to the latest insulation and smart features, and many come with construction warranties. However, community facilities typically lead to higher HOA fees compared to older buildings. In contrast, older buildings may have lower management fees, but if they are nearing the time for major repairs like plumbing or roofing, unexpected costs can arise.

Ultimately, the implications of these numbers are clear. In Boston, as the supply of new constructions decreases, it becomes difficult for new premiums to drop easily, and the low property tax rate supports the overall appeal of urban properties, including older ones. However, property tax rates and exemptions can vary based on individual parcels and residency requirements, so direct verification is necessary.

If you are looking for school districts preferred by Korean families, consider checking ratings from GreatSchools or Niche, but keep in mind that school district boundaries change frequently, so verify the assigned school for the address before signing a contract. If you are moving from another state, it's also good to factor in that Massachusetts property tax and insurance conditions may differ from your previous residence.

The harsh winters and heavy snowfall in New England are also variables. Older buildings may have lower insulation performance in roofs and exterior walls, leading to significantly higher heating costs in winter. The energy efficiency of new condos is particularly noticeable in such climates.

From an investment perspective, Boston's limited new supply means that the value of existing inventory, or older properties, tends to remain relatively strong. However, older buildings that are nearing the time for plumbing or roofing replacements carry the risk of significant expenses. There are no guarantees of specific returns or price increases.

In terms of insurance, older buildings with outdated plumbing or electrical systems may have higher insurance premiums. If you are considering a condo, it's advisable to check the master insurance conditions for the entire building as well.

There are also structural differences. Boston's older triple-deckers or brownstone buildings often have divided room layouts and shared laundry facilities, and some still use steam heating in winter. New condos typically feature open layouts and in-unit washers, with central heating and cooling as standard. If you are considering transitioning from renting to buying, older condos may have lower initial purchase prices but require separate budgeting for future remodeling costs.

Given the limited supply of new constructions in Boston, it seems more realistic to compare total costs, including taxes and management fees, rather than making hasty judgments based solely on price.
