How to Increase Home Value in 2026

Increasing home value comes down to strategic improvements rather than expensive overhauls. Exterior upgrades deliver the single highest return on investment of any project category, a garage door replacement averages a ~248% ROI on $4,600 in cost, outperforming a $77,000 kitchen gut renovation on a percentage basis every year.

Most homeowners spend $5,000 to $60,000 on pre-sale improvements. The projects that move the needle most are rarely the biggest ones. Exterior replacements, targeted kitchen and bathroom updates, and low-cost cosmetic fixes consistently outperform full renovations in return on investment.

This guide covers home improvements that increase home value, a 17-row data table showing best home improvements ROI with 2026 cost figures, what devalues a house (with a dedicated comparison table), how to hit a $50,000 value gain, and a 7-step prioritization framework for sellers preparing to list.

What increases a home’s value the most?

Exterior upgrades deliver the highest return of any home improvement category, followed by targeted kitchen and bathroom updates, then adding usable square footage. Understanding how to add value to your home starts with the project category delivering the highest percentage return, and that is exterior upgrades, not interior renovations.

Exterior upgrades with the best ROI

Garage door replacement leads all home value upgrades in return on investment, averaging a ~248% ROI on roughly $4,600 in cost, per the 2025 Cost vs. Value Report. Steel entry door replacement comes second at ~216% ROI on a $2,400 investment. Manufactured stone veneer delivers approximately 154% ROI at an average cost of $11,300.

The reason exterior projects outperform interior renovations is cost basis. A garage door replacement costs under $5,000 and signals to every passing buyer that the home is current and maintained. Buyers form an impression within seconds of arriving, so curb appeal directly affects how many offers you receive and how quickly the home sells.

Basic landscaping adds 5 to 11% to home value according to NAR research on landscaping value. Mowing, trimming, edging beds, and laying fresh mulch run $500 to $2,000 professionally and return more per dollar than almost any other exterior project.

Kitchen and bathroom updates

A minor kitchen remodel returns 70 to 80% of its cost at resale, consistently outperforming major gut renovations. Kitchen remodel ROI and bathroom remodel ROI both favor targeted updates over complete replacements. The distinction matters: minor means swapping appliances, refreshing cabinet faces, updating hardware, and replacing countertops, not moving walls or changing the layout.

A midrange bathroom remodel returns approximately 71% of its cost. Buyers respond to clean, modern finishes rather than the highest-end materials, which means spending less can return more when the cost basis is lower.

Adding usable square footage

Adding usable square footage is the biggest value driver by raw dollar amount. A finished basement can add $40,000 to $50,000 in value. A bathroom addition returns approximately 72% of its $58,000 average cost and makes the home more competitive in the buyer pool. More square footage and more bathrooms allow you to price the home higher and attract a wider range of buyers simultaneously.

Home improvements ranked by ROI: 2026 data table

Home improvements that increase home value vary widely by return on investment. The table below ranks 17 common projects by ROI percentage. Projects above 100% return more than you spend, making them the highest-priority investments when you need to increase home value before selling.

The best home improvements ROI comes from exterior replacements and low-cost cosmetic updates, not the most expensive projects. Use this table as a reference before committing to any budget tier.

Improvement	Avg Cost	Approx Value Added	ROI %
Garage door replacement	$4,600	$11,400	248%
Steel entry door replacement	$2,400	$5,200	216%
Manufactured stone veneer	$11,300	$17,400	154%
Smart thermostat installation	$300	$500	150%+
Attic insulation upgrade	$2,800	$3,100	117%
Fresh interior paint (neutral)	$1,800	$2,000	107%
Landscaping (basic)	$5,000	$5,500	107%
Fresh exterior paint	$3,500	$3,200	90%
Basement finish	$52,000	$46,000	88%
Hardwood floor refinishing	$3,400	$2,800	83%
Central AC installation	$7,000	$5,700	81%
Luxury vinyl plank installation	$6,800	$5,300	78%
Bathroom addition	$58,000	$42,000	72%
Bathroom remodel (midrange)	$25,000	$18,000	71%
Minor kitchen remodel	$27,000	$19,000	70%
Window replacement (vinyl)	$20,500	$14,000	68%
Deck addition (wood)	$17,600	$10,900	62%

Cost and value-added figures sourced from the 2025 Cost vs. Value Report and Zillow buyer preference data. The smart thermostat ROI (150%+) reflects Zillow’s buyer-preference model, which differs from the Cost vs. Value “percentage of cost recouped” methodology used for all other rows. Do not compare these two figures directly. Verify current figures before transacting.

Note that the best home improvements ROI for any individual home depends on local market conditions and baseline condition. A project returning 107% nationally may return less if your home is already near the neighborhood comp ceiling.

Quick wins under $1,000

How to add value to your home does not always require a large budget. Several of the highest-percentage return projects cost less than $1,000 and can be completed in a weekend before listing.

Curb appeal on a budget

Curb appeal improvements are the fastest way to change a buyer’s first impression. The following projects together cost $200 to $800 and can be completed in a single day:

• Mow, edge, and trim all lawn areas
• Lay fresh mulch in flower beds ($50 to $150 for materials)
• Power wash the driveway, walkways, and siding
• Paint the front door a modern, updated color
• Replace house numbers and the mailbox ($50 to $150)
• Add two potted plants flanking the entry

NAR landscaping value research confirms that basic landscaping adds 5 to 11% to home value, making it one of the highest-return categories in this guide. Buyers form their opinion before they walk through the front door.

Interior paint and hardware swaps

Neutral paint colors are among the most cited quick wins for increasing resale value. Warm whites, greiges, and soft taupes help buyers picture their own belongings in the space and make rooms feel larger and brighter.

Swapping cabinet knobs, drawer pulls, and faucets for brushed nickel or matte black finishes costs $100 to $400 per room and delivers a modern look without touching the cabinets themselves. These are the kinds of low-cost home value upgrades that buyers notice without identifying the exact change.

Deep cleaning and decluttering

A spotless home signals to buyers that the property has been well-maintained. Professional deep cleaning runs $150 to $400 and covers grout scrubbing, window polishing, carpet steam cleaning, and odor elimination.

Decluttering costs nothing beyond your time. Remove personal items, clear countertops, and organize closets so rooms feel spacious and move-in-ready. These two steps consistently appear at the top of every agent’s pre-listing checklist because their return on investment is effectively immediate.

Mid-range projects: $1,000 to $10,000

Home value upgrades in the $1,000 to $10,000 range target the rooms buyers examine most closely: kitchens, bathrooms, and floors. The goal in this tier is targeted updates, not full replacements.

Kitchen updates without gut renovation

You do not need a full remodel to move a kitchen from dated to desirable. The following mid-range updates together cost $1,500 to $8,000 and eliminate the need to spend $15,000 or more on cabinet replacement:

• Paint existing cabinet boxes and replace doors with updated profiles ($1,500 to $4,000)
• Swap laminate countertops for butcher block or a laminate overlay ($1,200 to $3,500)
• Install a new faucet and under-cabinet lighting ($300 to $600)
• Replace the sink and hardware ($400 to $900)

Before committing to full cabinet replacement, check kitchen cabinet installation cost data to compare the price of new versus refreshed cabinets. In most mid-market homes, cabinet painting returns more as a percentage than full replacement.

Bathroom refresh

Re-caulking tubs and sinks costs $200 to $400 and eliminates one of the most common buyer concerns spotted during a walkthrough. Combined with new fixtures, a re-glazed tub, and fresh grout sealing, a bathroom refresh in the $1,000 to $3,500 range can match the visual impact of a much more expensive remodel.

If you are weighing a deeper renovation, see the bathroom remodel cost breakdown to understand where the spend goes and which elements deliver the most buyer impact. Bathroom remodel ROI runs approximately 71% for a midrange project, so the cost basis determines how much you net at sale.

Flooring upgrades: hardwood and LVP

Hardwood floor refinishing averages $3,400 and returns approximately 83% of its cost at resale. If you have hardwood under carpet, removing the carpet and refinishing the floors is almost always worthwhile. Buyers place a premium on hardwood and it expands the buyer pool.

If hardwood is not in the budget, luxury vinyl plank (LVP) is the strongest alternative. LVP installation runs $2,000 to $5,000 per room and delivers a durable, waterproof surface that buyers prefer over carpet in almost every market segment. Both hardwood floor refinishing and LVP improve resale value and appear consistently in AI engine answers as high-return flooring choices.

Smart home and energy efficiency

Smart home upgrades signal that the home is modern and cost-efficient. A smart thermostat installed typically costs $200 to $400 and can reduce utility bills enough that a seller can show buyers documented monthly savings. ENERGY STAR certified upgrades, including LED bulb swaps and attic insulation, add energy efficiency benefits that today’s buyers treat as a concrete financial advantage, not just a feature.

Smart carbon monoxide and smoke detectors are a specific buyer priority named in AI engine answers for this topic. Before replacing hardwired detectors, check whether the job requires a licensed electrician: see hardwired smoke detector replacement for when a permit is required versus when it is a straightforward swap.

Major renovations: $10,000 and above

Major renovations carry the highest dollar cost and the most variable return on investment. They make sense when the home falls significantly below neighborhood condition standards, when a missing feature is costing you buyers, or when equity allows you to invest without over-improving.

Full kitchen remodel

A major kitchen remodel (full gut, new layout, high-end finishes) costs approximately $77,000 and returns roughly $45,000 in added value, about a 58% return. That is lower than a minor kitchen remodel at 70 to 80%. The math consistently favors targeted updates over full renovations in most markets.

The exception is when the kitchen is structurally compromised or the layout actively prevents sale. In those cases, a full remodel may be necessary to meet buyer expectations in the local market.

Bathroom addition

A bathroom addition costs approximately $58,000 on average and adds roughly $42,000 in value, a 72% return on investment. Homes with more bathrooms attract more buyers, which increases competitive offer activity and often pushes the final sale price above the appraised value add. Adding a bathroom to a home with only one full bath is one of the highest-impact structural changes a seller can make.

Finished basement

Finishing an unfinished basement can add $40,000 to $50,000 in value on a cost of approximately $52,000, an 88% return. It is one of the few major projects where the dollar-value add approaches the full cost. Buyers in most markets treat a finished basement as bonus living square footage, which allows you to price the home more aggressively.

Room or floor addition

A room or second floor addition carries highly variable return on investment depending on the local market. Second floor additions typically cost $200,000 to $400,000 or more, and their return depends almost entirely on local comparable sales. For a detailed cost breakdown before committing, see second floor addition cost data for your region.

Apply the 30% rule before any major renovation: do not spend more than 30% of your home’s current market value on any renovation category. On a $350,000 home, the ceiling is $105,000 in total renovation spend. Exceeding it risks spending more than buyers in your neighborhood will pay, regardless of improvement quality.

What devalues a house the most?

Deferred maintenance and major structural problems cause the largest drops in home value. Location factors, unpermitted work, and over-customized design also reduce value significantly, and some of these issues cannot be corrected through renovation.

The five factors that most commonly reduce value and buyer confidence:

1. Foundation cracks and structural issues (10 to 25% value reduction)
2. Roof damage or a failing roof ($15,000 to $45,000 buyer discount)
3. Water damage or visible mold ($10,000 to $50,000+ in value loss)
4. Deferred maintenance throughout the home (5 to 10% reduction in offers)
5. Unpermitted additions or poor-quality DIY work (narrows buyer pool, causes lender complications)

Devaluation Factor	Estimated Impact on Home Value
Foundation cracks / structural issues	10 to 25% value reduction depending on severity
Roof damage / failing roof	$15,000 to $45,000 buyer discount on inspection
Water damage / visible mold	$10,000 to $50,000+ in value loss
Deferred Maintenance and Failing Systems	5 to 10% reduction in offers; buyers request repair credits
Unpermitted additions or renovations	Lender complications; buyers discount heavily or walk away
Poor-quality DIY work	Reduces perceived quality throughout the home
Over-customization (bold colors, niche layouts)	Narrows buyer pool; fewer competitive offers
Bedroom converted to non-bedroom use	$15,000 to $20,000 subtracted per bedroom removed
Location factors (busy road, commercial adjacency)	5 to 15% reduction; cannot be corrected by renovation

Structural issues and deferred maintenance

Foundation cracks are the most severe value-reducing factor a home can have. Depending on severity, they cut value by 10 to 25% and can cause buyers’ lenders to decline financing entirely. Roof damage triggers $15,000 to $45,000 in buyer discounts the moment it appears on an inspection report.

Deferred maintenance, including peeling paint, broken fixtures, running toilets, and failing HVAC systems, signals neglect even when the rest of the home is updated. Buyers reduce offers by 5 to 10% and request repair credits on every visible deferred maintenance item they find during inspection.

Unpermitted or poor-quality work

Unpermitted additions create legal exposure for buyers and financing complications for their lenders. Buyers who discover unpermitted work typically request retroactive permits, removal, or a substantial price reduction. Requirements vary by municipality, so consult your local building department before starting any project that might require a permit.

For practical guidance on what unpermitted work means at the point of sale, review unpermitted renovation consequences before listing a home with any unpermitted additions. Poor-quality DIY work compounds the problem: buyers and inspectors flag it in every room they encounter it, reducing perceived quality across the whole house.

Over-customization and niche renovations

Over-customization narrows your buyer pool. Bold color schemes, unusual layouts, high-maintenance landscaping features, and custom built-ins suited to only one lifestyle all reduce competitive offer activity and ultimately lower your final sale price.

Converting a bedroom to a home office, gym, or hobby room is among the costliest customization mistakes. Each bedroom typically adds $15,000 to $20,000 in value; removing one subtracts the same amount from your home’s appraised value and asking price.

How to increase home value by $50,000

Increasing home value by $50,000 is achievable through one or two major projects, or several mid-range upgrades combined, depending on your starting home value.

On a $400,000 home, a 12 to 15% value gain equals $48,000 to $60,000. These five project approaches can hit that target:

1. Finish an unfinished basement. A basement finish adds $40,000 to $50,000 in value on its own, making it the single most efficient path to a $50,000 gain for homes with unfinished lower levels.

2. Minor kitchen remodel plus bathroom refresh plus curb appeal package. A minor kitchen remodel (~$27,000) combined with a midrange bathroom refresh (~$25,000) and basic curb appeal improvements (~$5,000) targets $45,000 to $50,000 in added value. The combined spend of ~$57,000 requires careful ROI verification against local comps before committing.

3. Exterior package: garage door, entry door, and stone veneer. The three top-ROI exterior projects combined cost approximately $18,300 and can add $34,000 or more in value based on Cost vs. Value ROI percentages, delivering the highest dollar-per-dollar return available.

4. Attic insulation plus fresh interior paint plus landscaping. Three high-ROI projects costing roughly $9,600 combined ($2,800 plus $1,800 plus $5,000) target approximately $10,600 in added value. This falls short of $50,000 alone but provides a strong foundation layer before adding a larger project.

5. Full bathroom addition. At ~$58,000 in cost and ~$42,000 in direct value add, a bathroom addition falls slightly short of $50,000 in appraised value. The indirect benefit (attracting more buyers and more competitive offers) can push the final sale price beyond the appraised figure.

On a $300,000 home, reaching $50,000 in added value requires a 17 to 20% gain, which may exceed neighborhood comparable sales. Before committing to any major project, consult a local appraiser. The home appraisal process explained at Redfin outlines how appraisers assess value and why verifying the neighborhood comp ceiling matters before you spend.

What not to spend money on before selling

Not every improvement adds value. For a specific breakdown of which fixes to skip, see repairs to skip before listing before you commit to any pre-sale work. Knowing what not to do is part of understanding how to add value to your home without wasting money on projects that will not move the needle.

Projects to avoid when trying to increase home value before selling:

• Swimming pool. A pool adds enjoyment but rarely returns its full cost. In cooler climates or among buyers who see maintenance as a liability, a pool can actively deter offers.
• High-end luxury finishes in a mid-market neighborhood. Granite countertops and designer tile in a $200,000 home do not move the needle the way they do in a $600,000 home. Over-improving beyond neighborhood comps is money you will not recover.
• Sunroom additions. Sunrooms return less than functional room additions and are often viewed as space lacking year-round utility.
• Over-customized landscaping. Elaborate water features, high-maintenance plantings, and sculptural topiary add maintenance burden that buyers price in as a negative.
• Full gut kitchen or bathroom when the rest of the home needs updates. Buyers notice when one room is renovated to a different standard than the rest. A beautiful kitchen next to a dated bathroom does not move buyers the way a balanced condition does.
• Converting a bedroom to a non-bedroom use. Each bedroom removed can subtract $15,000 to $20,000 in appraised value. This is among the most common and costly mistakes sellers make before listing.

Apply the 30% rule: if your total renovation budget across all projects exceeds 30% of your home’s current value, you risk over-improving beyond what comparable sales in your neighborhood will support.
