Home-sale preparation guide
Compare selling as-is with repairing before listing
Repairs can raise a sale price without increasing the seller's final check. The relevant question is whether the achievable price lift exceeds repair overruns, financing, extra carrying time, and selling costs tied to the higher price.
This calculator keeps the two net-proceeds statements side by side and shows the repaired sale price required to break even.
How to use this tool
Estimate both sale prices
Ask for an as-is and post-repair market opinion supported by comparable properties, not just a generic renovation return.
Define the repair scope
Use written bids, include permits or design costs, and add a contingency that reflects how much is still unknown.
Price the extra time
Count the months spent repairing, marketing, and closing along with property carrying costs.
Test the break-even price
Compare the required repaired price with conservative local evidence and rerun slower or more expensive cases.
Costs sellers often miss
- Percentage selling costs rise when the sale price rises
- Insurance, utilities, taxes, HOA, and mortgage interest continue during repairs
- Financed work can accrue interest before sale proceeds arrive
- Concessions and inspection negotiations can differ between the two buyer pools
Repairs are not equally valuable
Correcting a financing, insurance, safety, or inspection obstacle may affect marketability differently from a cosmetic upgrade. Model the specific scope and local buyer response instead of applying a broad national renovation-return percentage.
Net proceeds are not taxable gain
Mortgage payoff affects the check you receive but generally does not determine taxable gain. Basis, eligible improvements, selling expenses, ownership and use tests, depreciation, and local rules require separate tax analysis.
Certainty has value
An as-is offer may trade price for speed and a narrower risk window. A repair path may attract more buyers but introduces contractor, schedule, market, and inspection risk. Those factors remain visible as judgment calls rather than invented dollar adjustments.
This is a planning estimate, not an appraisal, contractor bid, inspection, legal opinion, tax calculation, or prediction of what a buyer will pay. Verify liens and settlement figures with the appropriate professionals.

Frequently asked questions
Does as-is mean I can avoid all disclosures?
No. Disclosure duties and contract rules vary by location and transaction. “As-is” generally describes the condition bargain; it does not erase applicable legal obligations.
Should mortgage principal be included as a carrying cost?
No. This model subtracts the remaining mortgage at sale. Include mortgage interest in monthly carrying cost, but adding principal payments there would double count principal that reduces the payoff.
How large should the repair contingency be?
Use an amount supported by the project's uncertainty. Work involving concealed conditions, older systems, permits, or incomplete bids generally deserves a more conservative scenario.
Why can a higher repaired price still lose?
The price lift may be consumed by the repair itself, financing, extra months of carrying costs, concessions, and selling costs calculated on a higher price.
Does the calculator include capital-gains tax?
No. Taxable gain is not the same as cash proceeds and depends on facts this calculator does not collect. Consult current official guidance or a qualified tax professional.
