Rehabilitation Budget Worksheet
A renovation budget is the single most scrutinized document in a rehab file, and a round number is not a budget. Build yours by trade, add a contingency, and get a total that underwrites. The same discipline that convinces a capital partner also protects you from the overrun that turns a good deal into a break-even one.
Estimate — illustrative only. Not a quote, a bid, or a guarantee of cost. Default values are placeholders, not RECR figures; replace every line with real contractor pricing for your specific scope and market.
Why Line-Item Budgets Underwrite and Lump Sums Don't
When a capital partner reads "$60,000 rehab" as a single number, there is nothing to evaluate. Is that a cosmetic refresh or a full mechanical replacement? Does it include the roof everyone can see is failing in the photos? Is there anything set aside for the surprise behind the wall? A lump sum answers none of these questions, so it gets treated as a guess — and a guess is exactly what underwriting is built to reject.
A line-item budget answers all of them at once. Broken out by trade, the same $60,000 becomes a scope: this much demo, this much roof, this much kitchen, this much mechanical. Each line can be checked against the property's condition, the local cost of that trade, and the photos in the file. A reviewer can see that the numbers add up to the work, and that the work adds up to the after-repair value the whole deal rests on.
It also protects you long before anyone else reads it. Forcing yourself to price each trade surfaces the line you forgot, the system you assumed was fine, and the finish level your comps actually require. Most budget failures are not overruns on a known line — they are lines that were never in the budget at all.
The Contingency Is Not Padding
Every real renovation encounters something the walk-through did not reveal — old wiring behind plaster, a subfloor that fails when the tile comes up, a code requirement that only surfaces at permit. The contingency is the line that absorbs those without derailing the project or forcing an awkward call for more money halfway through.
Underwriters read a budget with no contingency as a budget that has not been thought through. It signals either inexperience or optimism, and both raise risk on a structure that may already be carrying the full cost of the deal. A contingency sized to the age and scope of the property — heavier on older buildings and structural work, lighter on cosmetic refreshes — reads as an operator who has done this before.
On a 100% joint-venture structure the discipline matters even more, because there is no borrower equity cushion to quietly absorb a miss. The 100% purchase and rehab program is underwritten against total project cost within 70% of the after-repair value — and a realistic budget with contingency is what keeps that ratio honest instead of aspirational.
From Eight Lines to One Number
The subtotal is the sum of the trade lines. The contingency is a percentage of that subtotal. The total is what a lender or partner underwrites and what draws release against.
| Demolition & disposal | $4,000 | Tear-out, dumpsters, haul-off |
|---|---|---|
| Roof | $8,000 | Tear-off and replace, visible in comps |
| Kitchen | $12,000 | Cabinets, counters, appliances, labor |
| Bathrooms | $8,000 | Fixtures, tile, vanities |
| Mechanical (HVAC / plumbing / electrical) | $10,000 | Systems and code items |
| Flooring | $6,000 | Material and installation throughout |
| Interior (drywall / paint / trim) | $5,000 | Finishes and repair |
| Exterior (siding / landscaping / concrete) | $5,000 | Curb appeal and site work |
| Line-item subtotal | $58,000 | Sum of the eight trades |
| Contingency (10% of subtotal) | $5,800 | Reserve for the unforeseen |
| Total rehab budget | $63,800 | The number that underwrites |
Notice how the contingency scales automatically. Add a line, revise a trade, and the reserve moves with the subtotal — a heavier scope carries a proportionally larger cushion without you re-doing the math. That is the point of expressing it as a percentage rather than a flat figure: the protection stays matched to the size of the job. When the budget is complete, the total feeds two other numbers that decide the deal — how the funds release and whether the deal clears its ceiling.

Questions About Rehab Budgets
What contingency percentage should I use?
It depends on the property's age and the depth of the work. Cosmetic refreshes on a sound building carry a lighter reserve; older properties, structural work, and full mechanical replacements warrant more, because the odds of an unseen problem climb with the scope. The worksheet lets you set your own percentage so the reserve matches the risk of your specific project.
Should the contingency be a percentage or a flat dollar amount?
A percentage of the subtotal keeps the reserve proportional to the job, which is why underwriters prefer it and why this worksheet uses it. A flat figure that made sense on a $40,000 rehab is thin on a $120,000 one. Expressed as a percentage, the cushion grows automatically as the scope grows.
Does the contingency count toward my project cost?
Yes. Contingency is part of the total budget and part of total project cost, so it is included when a deal is tested against its ceiling. It is real money the project may need — treating it as invisible is exactly the mistake that pushes an overrun onto your own balance sheet.
How detailed does each line need to be?
Detailed enough that a reviewer can tie the number to the work. The eight trades here are the structure; strong submissions back each one with contractor estimates or a scope of work. The more your budget looks like a plan a professional priced rather than a figure you rounded to, the faster it moves through underwriting.
Why does a lump-sum budget get rejected so often?
Because it cannot be verified. A single number gives a reviewer nothing to check against the property's condition, the comps, or the photos, so it defaults to the most conservative reading — or a request to break it down before the file can move. Submitting a line-item budget from the start skips that entire round of back-and-forth.
How does this budget connect to my funding?
The total is the figure your rehab funding is sized to, and the trades become the schedule your draws release against as work is completed and verified. A clean, line-item budget is therefore not just a submission requirement — it is the map the whole draw process follows. See how the 100% purchase and rehab structure uses it.
