CapEx budgeting for manufactured housing communities
How to build a manufactured housing community capital budget that holds — unit-by-unit assessment instead of per-unit averages, the three invisible cost drivers, and how to phase across fiscal years.
Why these budgets overrun
Almost every manufactured housing community capital budget is built the same way: a per-unit renovation figure, applied across some proportion of the homes.
It is fast, it is defensible in a memo, and it is wrong in a specific and predictable way.
The variance between homes is enormous. Two homes on adjacent lots, same year, same manufacturer, same weather, can differ by a factor of four in what it costs to make them rentable — because one has a sound floor system and the other does not, and nothing visible from the doorway tells you which is which.
An average across that distribution is a bet on the mix. When the mix is worse than assumed, the budget does not overrun by ten percent. It overruns by a multiple on the affected homes.
The method that holds
Walk before budget season
In the quarter before your planning cycle. A walk producing numbers after submission is an argument, not a plan.
Assess unit by unit
Condition, recommended scope depth, and cost itemized line by line for every home — not a sample.
Look underneath
Belly, piers, anchors, drainage. The three invisible drivers. This is the step that distinguishes a real assessment from a walk sheet.
Separate community-level items
Roads, drainage, common structures, vacant lots and their infill readiness. These belong to no single home and get dropped from per-unit thinking entirely.
Sort by urgency, not cost
Failing now, deteriorating, dated. Three groups, three budget treatments.
Phase across years
Group one is this year regardless. Group two sets the order for the next two. Group three is discretionary.
The three invisible drivers
These are the items that never appear on a walk sheet and consistently blow up a budget. All three share a property: they are underneath or outside the home, so nobody looks.
Belly wrap and underfloor insulation
A torn belly lets ground moisture soak the underfloor insulation, which holds it against the deck continuously. The deck softens.
Communities pay for this repeatedly out of a maintenance line, having never seen the cause. If your records show subfloor repairs recurring in the same homes, this is why. Belly wrap and insulation.
Piers and anchors
Settlement presents as drywall cracks and doors that will not latch — which get costed and repaired as drywall and doors, annually, while the leveling is never done.
Anchoring has a second problem: corroded or slack tie-downs do not announce themselves at all. A home with no functioning anchoring looks exactly like one with it, every day, until the weather the system exists for arrives. Leveling, piers and tie-downs.
Lot drainage
Where a lot falls toward a home rather than away from it, everything underneath that home is on a clock — and every repair you make to the floor system has a shorter service life than the budget assumes.
Fixing the grade is one site work line that prevents several future lines.
Phasing: three groups, not one list
Everything on a community walk feels urgent when it is written down as a single list. Almost none of it is in the same category.
| Failing now | Deteriorating | Dated | |
|---|---|---|---|
| What it is | Active water entry, structural movement, life-safety at entries | Roofs and envelopes with measurable remaining life | Sound but old — limits rent rather than risking damage |
| Budget treatment | This year, regardless of what else is on the list | Sets the order of the next two years | Discretionary |
| Cost of deferring | Compounds. A leaking roof deferred is a deck repair scheduled. | Known and calculable — deferral is a decision with a price, not a saving | None, beyond foregone rent |
| Belongs against | Maintenance and capital | Capital plan | A repositioning decision, not a maintenance budget |
What it is
- Failing now
- Active water entry, structural movement, life-safety at entries
- Deteriorating
- Roofs and envelopes with measurable remaining life
- Dated
- Sound but old — limits rent rather than risking damage
Budget treatment
- Failing now
- This year, regardless of what else is on the list
- Deteriorating
- Sets the order of the next two years
- Dated
- Discretionary
Cost of deferring
- Failing now
- Compounds. A leaking roof deferred is a deck repair scheduled.
- Deteriorating
- Known and calculable — deferral is a decision with a price, not a saving
- Dated
- None, beyond foregone rent
Belongs against
- Failing now
- Maintenance and capital
- Deteriorating
- Capital plan
- Dated
- A repositioning decision, not a maintenance budget
The last row is the one that changes behaviour. Dated interiors compete for capital against deteriorating roofs in most budgets, and they should not — they are answering a different question.
What good output looks like
A spreadsheet you can build a budget from:
- One row per home: condition, recommended scope depth, itemized cost
- Community-level rows for roads, drainage, common structures and vacant lots
- Each row tagged failing / deteriorating / dated
- The three invisible drivers priced explicitly rather than absent
Not a proposal. A community walk is priced as its own scope precisely so the output belongs to you whether or not the contractor who produced it does the work — and an operator who takes it and bids the work competitively still has a materially better budget than they started with.
