A 1970 house, and the four questions the era raises

Houses of this period raise a well-defined set of questions, all answerable, none of them a reason to walk away, and all worth settling before an offer rather than after.

Aluminum branch circuit wiring first. It was used in residential construction from roughly the mid-1960s to the mid-1970s, and 1970 sits at the center of that window. The concern is not the wire itself but the connections, where expansion and contraction over decades can loosen terminations and generate heat. The remedy is specific and well established — proper connectors at every device — rather than wholesale rewiring, which makes it a manageable, priceable item when identified and a genuine hazard when ignored. An inspector will identify it in minutes if told to look.

Galvanized steel supply piping second. It corrodes internally over decades, so flow drops before anything fails; the symptom is poor pressure at upper fixtures rather than a leak. Replacement is disruptive but routine, and on a larger house it is priced by extent.

Lead-based paint third. Anything built before 1978 carries a federal disclosure requirement, which is a legal obligation on a seller rather than a matter of judgment. Intact paint under later coats is generally not a hazard; disturbed paint during renovation is the risk.

Clay or cast-iron drain lines fourth. On a street of this age with fifty-five years of tree growth, root intrusion into the lateral running to the sewer or septic tank is the ordinary failure. A camera inspection of that line is not part of a standard home inspection, costs comparatively little, and is among the better-value additional checks available here.

Insulation is the item most often left untouched, and 1970 levels are well below current practice. Improving the attic is among the most cost-effective things an owner can do in a Michigan winter, and the saving scales with the area of the house.

Tri-levels, and why the square footage misleads

A community holding colonials, ranches and tri-levels is holding three products, and the tri-level is the one whose measured area regularly misrepresents it.

A tri-level, or split-level, arranges the house on three half-story levels connected by short flights: typically living space on the entry level, bedrooms up half a flight, and a family room and utilities down half a flight. A bi-level, sometimes called a raised ranch, puts the entry on a landing between two full levels instead, and listings use the words interchangeably even though the layouts differ.

The lowest level is usually partly below grade, which means it may or may not count toward the official finished square footage depending on how far below grade it sits and how an appraiser treats it. Two houses with identical usable space can therefore be listed at different square footages, and comparing them on that number alone misleads in both directions.

For a buyer that is an opportunity, because usable lower-level space in a split is consistently underpriced relative to the same area upstairs. For a seller it is a reason to be precise about which part of the stated area sits below grade, because a surprise at appraisal is worse than a smaller number stated up front.

The form also has a distinct buyer pool: some people find the half-flights awkward, others value the separation of living and sleeping space the layout produces naturally. That means a wider spread of outcomes than a colonial of the same area, and comparables should be drawn from the same form.

The ranch is the third product and reaches the widest pool of all, because single-level living is a requirement rather than a preference for a substantial and growing number of buyers. Match on form before area, always.

A pair of 1970 neighborhoods, and how to use that

Brook N Ridge, elsewhere in the Dexter area, was built in the same year to the same mix of colonials, ranches and tri-levels. Two neighborhoods of the same era and the same forms a short distance apart is a genuinely useful thing for a comparable analysis, and it is the kind of relationship a listing never mentions.

Comparable depth is the scarcest commodity in this county's neighborhoods. Most communities here are small enough that in-neighborhood sales of a given form in a given year are rare or absent, which forces the analysis to widen — and widening without adjusting is exactly what an automated valuation does.

Where two neighborhoods genuinely share an era and a set of forms, the widening is disciplined rather than arbitrary. Match on era and form across both, then adjust for the differences: lot size, position, and whatever the recorded plats show about restrictions.

That last point matters here. Dexter Township, Webster Township, Lima Township and Scio Township all surround the city, and two neighborhoods a few miles apart can sit in different jurisdictions at different tax rates. That is an adjustment, not an equivalence.

The recorded plat for each is what makes the comparison rigorous rather than impressionistic: it gives the date, the proprietor, the lot count and dimensions, and the original restrictions. Where the two share a proprietor, the construction similarity is likely to run deeper than the forms alone — which would make an inspection finding on one genuinely informative about the other.

Worth checking, and free to check.

Fifty-five years of trees, and what they ask

A neighborhood established in 1970 now has canopy of that age, and mature trees are one of the things that most distinguish an established street from a new one. They cannot be bought at any price in a new subdivision.

They are also entirely the owner's obligation where they stand on private ground. A large tree close to a house is one to have an arborist look at rather than guess about; removal of a mature tree is a four-figure expense and periodic pruning a recurring one.

Roots interact with drains, driveways and foundations over decades — which connects directly to the drain lateral point above, and is why the camera inspection is one I add on a house of this age specifically on a street of this age rather than in general.

Canopy over a roof is the everyday version: leaf drop into gutters and valleys, which is exactly where roofs fail first, and shade that keeps surfaces damp and shortens the life of a covering.

Where trees stand in a public right-of-way rather than on the lot, they are usually the municipality's, and its rules govern what may be done to them — including by the adjoining owner. Worth asking rather than assuming.

Dexter is a city, and has been since 2014

Dexter was a village for most of its history and became a city in 2014, and a good deal of public data still calls it the Village of Dexter.

In Michigan the distinction is real. A village is an incorporated municipality that remains part of its surrounding township, so residents pay and vote in both. A city is separate from any township.

The larger point for anyone buying here is that a Dexter mailing address covers far more than the city. Dexter Township, Webster Township, Lima Township and Scio Township all surround it, and their mailing addresses read Dexter. Each is a separate government with its own board, tax rate, services, zoning and assessor, and the rate difference is real and recurring.

So comparable sales must be matched on municipality.

School assignment follows a third line again.

The Huron corridor above Dexter

The Huron River runs through this part of the county, and the corridor holds an unusual concentration of publicly held land.

Hudson Mills Metropark runs to 1,549 acres and Dexter-Huron Metropark to 122, both units of the Huron-Clinton Metroparks system held by a regional public authority, with Delhi Metropark downstream. They are linked to the town by Washtenaw County's Border to Border Trail, a paved route intended to cross the county end to end and part of Michigan's Iron Belle Trail.

Public and regional-authority ownership is the most durable tier of protected open space: not a business that can close and be sold, and not dependent on an association continuing to fund anything. In a directory where a great deal of adjoining green is an open question, this corridor is unusually settled.

For a specific parcel near the water, flood plain status is parcel-specific. Michigan regulates wetland at the state level and a township may regulate it further, which constrains what may be built, filled or cleared near water more often than people expect.

What to look up before a showing

The Washtenaw County Register of Deeds holds the recorded plat or master deed: the lot or unit count, the dimensions, the original restrictions, the proprietor and the date, and for a condominium the exhibit drawings showing every limited common element assignment.

Four tiers of protected open space, and a Michigan fifth

Where open ground adjoins a property, ownership is the first thing that decides whether it stays open — but not the only one.

Land held by a public body is generally the most durable, though a public body can still sell or repurpose land. Land under a recorded conservation easement is next — an easement runs with the land, surviving a change of owner and of local board. Association common area is real protection that the owners themselves pay for. Unbuilt private land carries the least protection of the four, but that is not the same as none: zoning, recorded deed restrictions and state wetland regulation can each constrain what may be built, filled or cleared, and EGLE requires authorization for specified activities affecting regulated wetland.

From a window all four look identical, which is why it is worth checking the record rather than the view: ownership, any recorded easement or restriction, the zoning, whether wetland is mapped, and whether a development application has already been approved.

Buying or selling here

The era checks are the whole of it, and they are cheap relative to the decision.

For a seller, inspection-grade answers on the wiring and the supply piping, dated records for the roof, heating and any rewiring, and the lead-based paint disclosure handled properly remove nearly everything a buyer of a 1970 house will worry about. Where the wiring has been remediated or the plumbing replaced, say so with documentation — those are the two most valuable sentences available for a house of this age.
