What does 5 acres with a house cost near Nampa Idaho, and what does it cost to keep?

About $1,100,000. That is the asking price on 12369 Deer Flat Road. It buys 5.34 fully fenced acres and a 3,029 square foot house on a hilltop west of Nampa. Now here is the number that actually sells a place like this. Zero. That is how many CC&Rs come with it, and for the right buyer it is worth more than the granite. Most acreage makes you choose between the land, the house and the drive. Here is the honest accounting on all three.

What does acreage with a house run near Nampa?

At this property it is $1,100,000, which works out to $363.16 a square foot on the house. That per foot number looks high until you remember what it includes.

You are buying 3,029 square feet plus 5.34 acres. Add a barn, a shop, a corral, two fenced pastures and a hilltop. The house is the part with a price per foot. The rest is the reason anybody drives out.

I would not compute a price per acre here. Improved acreage and raw ground are different products. Dividing the whole price by 5.34 tells you nothing useful.

Horses and chickens are both allowed. There is RV parking, the perimeter is fully fenced, and the property sits on a public road.

What does no CC&Rs actually get you?

It gets you the right to use your own land without asking a committee. Nobody reviews your paint color. There is no rule about how many vehicles sit in the driveway, and no dues, because there is no association to pay.

For somebody who wants a shop, a trailer, a corral and a chicken coop, that is the entire point. Covenants are usually what stops all four.

Now the honest half. Nothing governs your neighbors either. There is no board to call if somebody parks a project car in view of your porch. If you have only owned inside a subdivision, sit with that trade before you write.

What does it cost to own a well?

Less in monthly bills and more in attention. There is no water utility here, so the tradeoff is that nobody is testing your water except you.

The Idaho Department of Environmental Quality puts it plainly. “Well owners are responsible for ensuring their water is safe.” Their guidance is that “private wells should be tested for nitrate and bacteria at least once per year.”

The Idaho Department of Health and Welfare adds a second layer. Bacteria and nitrates once a year. Metals and chemicals every three to five years. DEQ also names nitrate, bacteria and arsenic as three of the most common groundwater contaminants in this state.

So budget an annual test, and know that you also own the pump and the pressure tank.

What about the septic?

You own that too, and it runs on a maintenance schedule rather than a utility bill. Septic in Canyon County falls under Southwest District Health, and that is who I would call with a question about the system on any acreage property.

During due diligence I would do three things. Pull the permit record on the existing system, have it inspected and pumped, and find out how old the drainfield is.

None of that is hard, and all of it is cheaper before closing than after. A septic system costs almost nothing for twenty years. Then it costs a lot in one afternoon.

What is the land set up to do?

It is set up to work, which is unusual even on acreage. There are two separately fenced pastures ready for animals, a 40×26 barn and a corral.

Then the growing side. A chicken coop, a big garden, and fruit trees, berry bushes and grape vines that are already producing. A pond sits on the property, and there are mature shade trees.

The 30×24 shop sits steps from the back door, which matters more than square footage does. A shop across the property is a shop you stop walking to in January.

Where are the bedrooms?

All four are upstairs, and you should know that going in. The main floor holds the living room, the family room at 15 by 27, the eating area, the entry and the laundry, plus a half bath.

So there is no bedroom on the main level and no primary suite on the ground floor. The primary is upstairs at 13 by 21.

That runs against where most of this valley is heading, because single level living is the biggest lane in the market. Say stairs are a factor now, or you are buying your last house. Then this floor plan is the honest reason to keep looking.

Is some of that square footage a garage?

Some of it is, and I would rather tell you than let you find it at the appraisal. The attached garage is insulated, heated and cooled, and 540 of its finished square feet are counted in the 3,029 total.

Back that out and you are looking at roughly 2,489 square feet of conventional living space, plus a very comfortable garage. Whether that is good or bad depends entirely on you.

For somebody who works on projects year round, a conditioned garage is a feature worth paying to add. For somebody counting bedrooms per square foot, it changes the math. Either way it belongs in your comparison, not in the fine print.

What do the taxes and the heat run?

Taxes are modest for the price. The 2025 bill was $2,327.30, and the homeowner’s exemption is already on the property. A new owner still files their own with the county assessor.

Heat is the line I would look at harder. The house runs electric forced air with a pellet fireplace, and electric heat on a hilltop with a lot of glass is a different bill than gas.

There is no HOA, so your fixed monthly costs are the mortgage, the taxes, the insurance and the power. Ask the sellers for twelve months of utility bills. On a rural property that one request tells you plenty.

Who should not buy this?

Somebody who wants a turnkey suburban life with acreage bolted onto it. Land is a chore list. The people who love it are the people who wanted the chores.

I would also point you elsewhere if you need a main floor bedroom, or if a well and a septic system sound like risk rather than independence. Neither of those is a flaw in the property. They are just the wrong fit for some buyers, and I would rather say so now. And if your commute runs to the east side of Boise, drive Deer Flat Road and Highway 45 at the hour you would actually leave.

So what is the real trade here?

The trade is maintenance for freedom, and that is the whole decision. You pick up a well, a septic system, fences, pastures and a long driveway. You put down the dues, the committee and the shared wall.

What makes this one unusual is what it does not ask you to give up. Ten minutes from town, a renovated main floor, and a shop you can reach in your slippers. It is owner occupied, so showings run by appointment rather than off a lock box.

Most acreage makes you pick two out of three. That is the part worth looking at in person.
