Factors Affecting Land Prices
Many buyers overlook key factors that impact land prices. A clear insight about these variables can assist you to make smarter decisions:
- Infrastructure: Lands with water supply, sewage, electricity, roads, and other amenities are typically expensive.
- Terrain: Flat fertile land costs more than rocky or uneven plots.
- Location: Plots in urban regions cost more than the ones in rural areas. For instance, upstate NY costs less, has more land and fewer people than Manhattan.

How Big Is an Acre When You Plan to Build a Home?
A typical single-family uses 1/5th of an acre or 8,700 square feet. To estimate your ideal land size, calculate your family’s space needs. Then choose land based on how you want to build a house to match your vision.
You can also use the land-to-building ratio to estimate your ideal land size. This ratio ranges between 2.5:1 and 3.5:1 and compares lot size to home size. For a 0.15 acre home, the land size should be between 0.375 and 0.5 acres. Use this formula to calculate:
Land size = Land-to-building Ratio * Home Size.
Acreage or Home Size: Which Matters More?
When you buy a home, you may face a choice—more land or a larger house. Here are the pros and cons to help you compare acreage versus home size. You should weigh in the pros and cons of choosing acreage over home size to make an informed decision.
Pros 👍
- More Outdoor Space and Expansion Potential: You get ample outdoor space for a patio, garden, pool, guesthouse, recreation, and much more.
- More Privacy: You can enjoy an increased buffer from neighborhood and street noise. Moreover, fewer neighbors offer you more seclusion for outdoor activities and relaxation.
- Lower Property Tax: Many states base property taxes on home size or square footage. So, a larger land size with a smaller home might lead to lower taxes.
Cons 👎
- Extra Upkeep: Larger plot size requires higher maintenance, such as extra efforts to mow, clean and landscape.
- Increased Expenses: Property taxes and utility costs often rise with bigger land sizes.
- Reduced Indoor Space: A bigger plot size might require you to compromise on the home size and interior upgrades.
- Limited Nearby Facilities: Homes on large plots often have limited access to local facilities and services.
