Fixer-Upper vs. Move-In Ready: Which Is the Better Deal?

You're scrolling Zillow and you spot it: a house for $180,000 in a neighborhood where homes sell for $280,000. The catch? It needs a lot of work. Is this a hidden gem or a money pit? Here's how to figure it out before you make an offer.

70%
Rule: max price = 70% of ARV minus repairs
15-20%
Add to every contractor estimate as a buffer
$250k
Tax-free gain if you live there 2+ years

Run the 70% Rule First

Before you fall in love with a fixer-upper, do this math. Figure out what the home will be worth after all repairs are done. That's the After-Repair Value (ARV). Then get real contractor bids on everything that needs fixing. Then apply the 70% rule.

Real-world example

ARV in that neighborhood: $280,000. Contractor bids for kitchen, bathrooms, roof, and flooring: $65,000. Apply 70%: $280,000 x 0.70 = $196,000. Subtract repairs: $196,000 - $65,000 = $131,000. That's the most you should pay. At $180,000, you're overpaying by $49,000. That deal that looked like a steal actually isn't one.

Get 3 contractor bids, not 1
Never make an offer on a fixer-upper based on one estimate. Prices vary wildly between contractors. Get at least three bids, take the average, and add your 15-20% buffer on top. That's your working renovation budget.

The Costs Most People Forget

  • Contractor overruns are normal. Once walls open up, surprises show up. Budget 15% to 20% on top of every estimate, no exceptions.
  • Carrying costs add up fast. Every month the home sits under renovation, you're paying mortgage, insurance, and taxes with nobody living there. On a $180,000 purchase, that's $1,200 to $1,500 a month while workers show up three days a week.
  • Cosmetic vs. structural is a huge difference. New paint, floors, and fixtures? Predictable cost, great return. Old plumbing, bad wiring, foundation issues? These can spiral fast. Triple-check your bids and always have a contingency.
  • Permits cost time and money. Major renovations require permits. Add 4 to 8 weeks of timeline for permit processing in most cities, plus the permit fees on top of that.
When it all goes sideways

A buyer purchases a fixer for $160,000 expecting $40,000 in renovations. After opening walls, they find knob-and-tube wiring that needs full replacement: add $18,000. Then a slow contractor stretches the project from 3 months to 7 months, adding 4 extra months of carrying costs at $1,400 a month. The project went from $40,000 to $65,600. Budget for surprises or they will budget you out.


When a Fixer-Upper Actually Makes Sense

  • The numbers still work even with a conservative estimate and full buffer
  • The neighborhood has strong comparable sales to support your ARV
  • You have contractor connections or can do some of the work yourself
  • It will be your primary home and you plan to live there 2+ years
The 2-year tax bonus
If you live in the home as your primary residence for at least 2 of the last 5 years before selling, you can exclude up to $250,000 in profit from capital gains taxes ($500,000 if married). That's a massive advantage for owner-occupant renovators and something most people overlook.

Move-In Ready Has Real Value Too

A move-in ready home at a fair price often beats a fixer-upper once you factor in everything: the cost of your time, the stress of managing contractors, months of carrying costs, and the inevitable surprises. Fixer-uppers can be great deals. They can also turn into financial nightmares. The difference is almost always in how carefully you run the numbers before you commit.
