What to Know Before Buying Land in the White Mountains of Arizona

Buying land in the White Mountains of Arizona can offer space, privacy, and flexibility—but it also comes with considerations that aren’t always obvious from a listing. Before focusing on price or acreage, it’s important to understand how land actually functions in this area.

Perc Tests and Septic Systems

Not all White Mountains AZ land will support a standard septic system. A percolation (perc) test determines whether the soil can absorb wastewater properly for the desired use.  Perc tests determine the maximum number of bedrooms a residential structure can have.  How fast or how slowly the water drains "percolates" through the soil determines the number of bedrooms a system can accommodate. Perc tests are most usually a buyer cost, but can be negotiated between buyer and seller. Never forego a perc test, and always consider making a "passed perc test" a contingency for purchase.

In the past, some non-perc properties were modified using methods like “shooting” the ground to improve absorption or set leach lines. That practice of dynamiting is no longer allowed due to concerns about damaging subsurface formations, including the Coconino Aquifer, the region's main source of water.

If land does not perc, alternative septic systems may be required—and these can significantly increase costs. Depending on the conditions of the land, costs can exceed $25,000.

Utilities and Power Access

Some parcels—especially in more remote areas—may not have access to electricity, and in some cases, it may not be feasible to bring power to the property at all. Rural parcels may not have access to everyday services. Of note, most residential properties in the White Mountains use propane for heat. Always verify whether the propane tank is leased or owned.

Understanding the types of utilities available, the distance to utilities and the cost of extending service is an important step before purchasing.

Water: Wells, Hauling, and Availability

Water is one of the most important considerations when buying land.

Wells: There are wells that are specifically for livestock, and there are wells for domestic consumption. Know the difference. It's a good idea to get a water potability test performed on a domestic well during the inspection period.

Drilling a well can be expensive, often starting around $50,000 depending on depth and conditions. Checking nearby well depths can provide insight, but does not guarantee results. For information on area wells and a specific well, check with AZ Department of Water Resources

Water Companies: Some local water providers have limited capacity or aging infrastructure and may not be able to extend new service.

Haul Water: In some areas, hauling water is the only option. This requires:

A storage tank (cistern)
A delivery system (gravity or pump)
Access to a legal water fill station
Each option has its own costs and long-term considerations.

Well Shares:

Some properties are served by shared wells. Before purchasing, it’s important to understand:

Who owns the well
How many properties share it
Whether the agreement is recorded
Maintenance responsibilities
Water usage limitations

Well share agreements can vary widely, and not all are structured the same.

Terrain and Usability

Not all acreage is fully usable. Steep terrain, dense vegetation, or difficult access can limit where and how a property can be developed.

What looks like “10 acres” on paper may function very differently depending on layout and topography.

Rock and Soil Conditions

In many parts of the White Mountains, especially areas with volcanic or rocky soil, surface conditions can change over time.

It’s not uncommon for land that has been cleared or graded to produce more rock later. What appears manageable initially may require ongoing work depending on the terrain. This is an essential consideration for buyers wanting to purchase horse property.

Soils depths in some areas are shallow and close to bedrock. Others may be alkaline and high in clay. There are many washes throughout the area that can flood. And there are underground "streams" beneath some land that cannot be seen-- sometimes vegetation in winding patterns can be observed.

Observe and ask about any washes visualized on land that interests you. Washes are unusable, and in many cases may make access after storms impossible. Runoff from higher elevation land can also be problematic with thick abiding mud long after a storm has passed. During monsoon season, roads that appear dry on the surface can conceal deep mud underneath. This can make travel difficult or even unsafe, particularly on unmaintained roads.

Property Boundaries, Surveys, and Lot Lines

Understanding where a property begins and ends is not always as straightforward as it seems. In Arizona, land is conveyed by a legal description, not by visible markers on the ground. This may be:

A subdivision name and lot number
A metes and bounds description for larger or unplatted parcels

In both cases, there is typically a recorded plat or legal description that defines the property—but that doesn’t mean the boundaries are clearly marked in the field.

Don’t Rely on Visible Markers

Buyers are sometimes shown:

Survey pins
Stakes
Flagging tape or ribbon

These can be helpful—but they should not be relied upon without verification.

Markers can be:

Moved over time
Disturbed by weather, animals, or equipment
Incorrectly placed or assumed to be accurate

It’s not uncommon for pins to be difficult to locate—or missing entirely.
Survey and Staking

If property boundaries are important to your decision, you may want to request:

A professional survey
“Staking and flagging” of the property corners and lines

This provides a clearer, more reliable understanding of where the property lies on the ground.

Why This Matters
Boundary uncertainty can affect:

Fencing
Building placement
Access
Relationships with neighboring properties

Relying on assumptions or informal markers can lead to costly issues later.

In rural areas especially, it’s always better to confirm boundaries before making plans based on what appears to be the property line.

Local Regulations and Restrictions

Some properties are subject to:

HOA rules
CC&Rs (Covenants, Conditions & Restrictions)
County zoning requirements

These may affect:

Recreational use
RV use
Building timelines
Property use

Understanding these restrictions ahead of time helps avoid surprises.

Land Buying Checklist: What to Confirm Before You Buy

Before purchasing land in the White Mountains, take time to verify the details that can affect how the property can actually be used.

✔ Water
Is there an existing well?
If not, what are nearby well depths?
What is the estimated cost to drill?
Is water haul required? If so, from where?

✔ Septic & Soil
Has a perc test been completed?
Will the property support a standard septic system?
If not, what are the alternatives and costs?

✔ Access
Is there legal, recorded access?
Are the roads maintained year-round?
Will weather affect accessibility?

✔ Utilities
Is electric available at the property line?
If not, what would it cost to bring power in?
Are alternative systems (solar, generators) needed?
Is the propane tank leased or owned?

✔ Boundaries
Are property corners clearly identified?
Has the land been surveyed?
Is staking and flagging needed to confirm boundaries?

✔ Terrain & Usability
Is the land buildable?
Are there slopes, washes, or rock issues?
How much of the acreage is actually usable?

✔ Zoning & Restrictions
What is the zoning designation?
Are there HOA rules or CC&Rs?
Are there restrictions on RV use or camping?

✔ Water Systems & Alternatives

Is there a private well?
Is there access to a water company?
Are there infrastructure limitations?
If hauling water, what equipment is required?

✔ Well Shares (if applicable)
Who owns the well?
How many properties share it?
Is there a recorded agreement?
What are the maintenance responsibilities

Taking the time to confirm these details can help avoid unexpected costs and ensure the property fits your plans long-term.
