Walnut Glen

One to three bedrooms inside a 30 percent size range

The size range here is narrow — about 30 percent from smallest to largest — but the bedroom count runs from one to three, which is a much wider spread proportionally. That combination is worth reading carefully, because it means the difference between units here is how the space is divided rather than how much of it there is.

A one-bedroom unit at a thousand square feet is a genuinely different product from a three-bedroom unit at thirteen hundred. It serves a buyer who wants generous rooms rather than more of them, and — in a university city with two large hospital systems nearby — a buyer who intends to lease. That second group makes the association's leasing rules a value question as well as a living one: how many units may be leased at once determines what a unit can be used for and therefore who can buy it. Those rules can be amended, so the current document is what matters.

For a comparable analysis this means bedroom count does more of the work than square footage does, which is the reverse of the usual arrangement. Two sales at the same area and different bedroom counts are not evidence for each other.

It also means the community's own sales are usable evidence within a bedroom count and misleading across one — which is a discipline an automated valuation will not apply, because it treats the area figure as the anchor and adjusts from there.

Bathroom count carries the same weight for the same reason. Michigan listings state full bathrooms before the decimal and half bathrooms after, so two-point-one means two full and one half. Both that convention and the common national one appear in this county's data, so count fixtures at a showing rather than trusting the notation.

Three forms, and the ranch among them

Ranches, two-story homes and attached units are three products competing for three buyer pools even where their areas overlap.

The ranch is the one to separate first. Single-level living with no internal stairs reaches a persistent and geographically wide buyer pool: people for whom it is a requirement rather than a preference, and who will consider nothing else. There are always more of those buyers than there are single-level homes, which is why ranches routinely outperform what their measured area suggests and why the gap tends to widen rather than narrow.

That holds only if the unit itself is reached without stairs, which is the question people forget to ask. A single-level unit up a flight of stairs excludes exactly the pool the form is otherwise made for. A step at the entrance is enough to matter to some of that pool.

A two-story home is the reference product with the deepest comparable data. An attached unit is the broadest category, and the specifics that matter are how many walls are shared and whether anything sits above or below.

There is also a Michigan question worth settling: a detached home here may be a platted lot or a site condominium, which is invisible from the curb and material for pricing, since a subdivision sale needs adjustment before it can stand as a comparable for a site condominium or the reverse. The recorded instrument settles it.

In a community where area barely varies, form and position are most of what separates two sales — and they are precisely what an automated valuation handles worst.

A second 2002 Walnut nearby

Walnut View, on Scio Ridge, was built in the same year, sits about the same distance from downtown, and holds a similar mix of forms at a slightly larger size.

Two communities with similar names, the same build year and similar product, close together, is precisely the arrangement that produces mixed comparables. It is useful for widening a thin sales record and it is a trap if the widening is done without adjusting.

They are separate recorded projects with separate associations, separate assessments and separate reserve positions. A sale in one is a candidate comparable for the other rather than evidence for it, and the adjustment people skip is frequently the largest: two physically similar units can carry very different monthly costs and very different exposure to a coming special assessment, and neither shows up in a price per square foot.

So identify the recorded project for every candidate comparable, then compare what the assessment covers before comparing the numbers.

For a seller, a listing should carry the recorded project name rather than the short one, so a buyer comparing against the other community knows they are comparing across a boundary.

A 2002 build at around twenty-three years

A single-year build means the units are genuinely one product — one code cycle, one generation of materials, one construction period — which makes an inspection finding on one unit informative about the others and makes comparable sales unusually reliable.

These are modern-code buildings with modern insulation, modern electrical service and modern egress.

What twenty-three years brings is the leading edge of the first replacement cycle, arriving across the community at once because it was built together. Original water heaters are at or beyond normal expectancy. Original air conditioning is approaching it. Furnaces are generally still within their expected life but not by much. Original roofs are in the second half of a typical asphalt shingle service life rather than at the end of it, which makes this the period when roof condition genuinely varies from building to building depending on exposure, ventilation and the quality of the original work.

Attic ventilation is worth a specific look for exactly that reason: a poorly ventilated roof space shortens shingle life measurably, and at this age the difference is starting to show.

Original glazing units begin to show seal failure as fogging between the panes around this age, and in a condominium the windows are usually common or limited common element, so replacement is a building decision rather than an owner's.

The item specific to this period is exterior cladding and its edges. Composite and hardboard products perform according to how their ends, edges and penetrations were sealed and how the ground drains away. The bottom courses, and anywhere a deck or porch meets a wall, are where the original detailing shows.

So the reserve study is the document that matters, and the question is not whether the roofs are due but whether the money is there.

What the association documents decide

Buying a condominium unit means buying into a corporation as well as a home, and the corporation's condition is not visible at a showing. Four documents settle it: the master deed and its exhibits, the bylaws, the current budget and the reserve study.

The master deed defines what the unit actually is — where the boundary runs between unit and common elements, and what limited common elements are assigned to its sole use. That is the most misunderstood part of condominium ownership, and it decides who pays for a great many things.

The bylaws set the rules that govern daily life: what may be altered, what may be parked, whether units may be leased and how many at once, and how the board is elected.

The budget and the reserve study together answer whether the association is solvent. An association with thin reserves and a large component near the end of its life is not cheaper — it is a deferred bill with an unknown date, and it arrives as a special assessment.

Board minutes are where a coming expense, a dispute or a construction defect claim surfaces first, and they are the most informative document nobody reads. I go through the recent ones as a matter of course.

One Michigan detail worth knowing: condominium documents are amended by recorded instrument, so what is recorded governs regardless of what any summary says.

The wall between two households

In any attached housing, the wall or floor between two households is the variable that most affects daily life and appears in no listing.

What matters is the assembly rather than the finish: a genuine double stud wall with an air gap performs far better than a single framed wall with insulation, because sound travels through structure as readily as through air. Where a floor separates two households, footfall carries downward and carpet helps without solving it.

An end unit has one shared wall instead of two, which is a real and priceable difference that square footage ignores entirely.

The reliable test is the simplest: visit at an hour when people are home — an evening or a weekend — rather than mid-morning when the building is empty.

Four Walnuts under one city heading

Four separate communities in the Ann Arbor area begin with Walnut — Old Walnut Heights on the west side, Walnut Glen on Joyce Lane, Walnut View on Scio Ridge, and Walnut Ridge — plus a Walnut Creek in Plymouth. They are not the same place and several are not in the same municipality.

That matters for a practical reason rather than a tidy one. Any search working from names rather than from recorded documents blends them, and a model pulling comparable sales on the word Walnut mixes several markets into one number. Where the communities sit in different municipalities, the tax rate and the school district differ too, so the blend is wrong in more ways than one.

The fix is the same in every case: identify the recorded project rather than the marketed name. The Washtenaw County Register of Deeds holds the master deed or the plat, which gives the legal name, the number, the address and the boundary. That is the identifier a comparable analysis should be built on.

For a seller it is worth stating the recorded name in a listing rather than the short one, and for a buyer it is worth checking that a comparable offered as evidence is actually from this community.

An Ann Arbor address is not necessarily the City of Ann Arbor

The City of Ann Arbor is ringed by townships — Scio, Pittsfield, Ann Arbor, Superior and Lodi among them — whose mailing addresses read Ann Arbor. A mailing address is a delivery route rather than a jurisdiction.

Each township is a separate government with its own board, tax rate, services, zoning and assessor. The rate difference between a city parcel and a township one is real and recurring, which is why comparable sales must be matched on municipality. Rates and taxable values both change, so compare the current millage and the parcel's own taxable value rather than a remembered difference; a tax bill arrives on the local schedule, and a lender collects an estimated share of it monthly.

School assignment follows a third line again. Three distinct versions of the split exist around here — Ann Arbor addresses with Pittsfield taxes and Saline schools; Pittsfield taxes with Ann Arbor schools; and a Ypsilanti address with Pittsfield taxes and Ann Arbor schools — which together show that no direction of inference works.

Schools

Walnut Glen is served by Ann Arbor Public Schools. District boundaries are redrawn from time to time.

Buying or selling here

Bedroom count does the pricing here, not area, which is the reverse of the usual arrangement.

For a seller, that is an argument to make explicitly rather than leave to a model: state the bedroom and bathroom counts precisely, name the form, and name the recorded project rather than the general area.
