Thinking about renovating before you sell? Get a realistic cost range for your project in about thirty seconds — the same planning numbers used to decide what’s worth doing, and what isn’t, before a home goes on the market.
Your planning estimate
Share of the mid-point budget, with a dollar range for each line. These are the items to get real bids on first.
Budget a 10–15% contingency on top. Opening walls finds things — older plumbing, wiring, and subfloor surprises are the rule, not the exception, in homes over 25 years old.
This is a planning estimate, not a quote. A real number requires a walkthrough — layout, condition, permits, and material choices move the price more than square footage does.
The estimate above is the headline. The checklist is the working tool: it walks the same project room by room, so you can tell in one pass what’s a weekend fix, what needs a contractor, and what isn’t worth touching before you list.
When you’re selling, every dollar has to argue for itself twice: once in the sale price, and once in how fast the home moves. Three rules of thumb from the renovate-to-sell work behind this estimator:
Paint, flooring, lighting, and hardware carry most of what a buyer feels walking in — usually for a fraction of a full remodel. Save the gut renovation for the next owner’s dreams, not your budget.
Buyers forgive a dated bedroom; they discount a dated kitchen or primary bath on sight. At basic-to-mid finish, these rooms have historically returned the strongest share of their cost at resale — roughly 65–85 cents on the dollar in recent Cost vs. Value data — and the return falls as finishes climb.
A buyer won’t reimburse you for the imported tile they would never have chosen. Mid-range, widely appealing materials price your home against the neighborhood — premium materials price it above the neighborhood, and appraisals notice.
The full worksheet version of these rules — with per-room cost tables and a feasibility pass for permits, timeline, and budget — is in Sherry’s Homeowner Renovation Guide, the companion to this estimator.
Rates are planning figures for the project area (the kitchen’s own square footage, not the whole house), drawn from published 2026 cost data — including Remodeling Magazine’s Cost vs. Value reporting and current contractor pricing guides — then adjusted for local labor by market. Treat the range as the honest answer to “roughly what?”:
