Selling a House That Needs a Full Remodel

A house that needs a full remodel has three realistic buyers: a cash buyer who prices the work into the offer, an owner-occupant who finances the purchase and the renovation together, or the open market after you do the remodel yourself. Dated is not the same as unfinanceable. Under Fannie Mae's rules a house with obvious deferred maintenance that still works as a home can be financed as it is, while one with problems affecting safety, soundness or structural integrity has to be repaired first. Which path nets most depends on the scope, the permits and whether you can carry the months.

This article is part of the fire, water and repair-heavy houses section. When the work comes from a fire or a flood rather than age, start with rebuild first or sell now instead.

What "needs a full remodel" usually means

Owners use the phrase for two very different houses. One is dated: the original kitchen and baths, worn floors, an old roof, a layout nobody would build today, but everything works. The other has failing systems or structure under the finishes: an original electrical panel or old wiring, galvanized supply lines, a roof past repair, a foundation that has moved. Buyers and lenders treat those two houses differently, so the first job is to sort your list into "dated" and "failing."

Where the house sits says a lot about what is on the list. Around Claremont Village the oldest bungalows and period houses are the ones with original knob-and-tube circuits, galvanized plumbing, raised foundations and enclosed back porches that became bedrooms; in the post-war ranch tracts north of Foothill Boulevard the recurring items are original panels, galvanized supply lines and converted garages. In Chino Hills the same phrase often means a planned-community house bought new decades ago, still in original condition, with dated kitchens, baths and roofs.

Where a lender draws the line

Fannie Mae's Selling Guide rates every house it finances on a condition scale. A C5 house has "obvious deferred maintenance" and is "in need of some significant repairs," but stays useable and functional as a residence, and houses rated C1 through C5 are eligible "as is." A C6 house has conditions "severe enough to affect the safety, soundness, or structural integrity of the improvements," and a loan on it is not eligible for sale to Fannie Mae until the deficient items are fixed.

That line is the one that matters for a sale. A dated but sound house can still reach ordinary financed buyers; they simply pay less for it and plan the remodel themselves. A house with failing structure or systems loses most of them until the work is done, which leaves cash buyers and buyers with a renovation loan. The pattern is laid out in as-is listings that attract only investors.

The renovation-loan buyer

Some financed buyers borrow for the house and the remodel at once. Fannie Mae's HomeStyle Renovation mortgage is one such loan, written for purchase and refinance transactions on principal residences, and on one-unit second homes and investment properties. Its rules shape what happens in your escrow:

• The lender uses the buyer's plans and specifications to judge the scope, quality and cost of the work and to set the loan amount.
• The appraisal must give an "as completed" value, an estimate of the house after the renovation, built from those same plans.
• The renovation work must be done by a licensed contractor or subcontractor, where licensing applies, and the lender has to confirm the contractor's qualifications.
• If the scope changes, the lender must get an updated appraisal to see whether the as-completed value moves.

For a seller, that means the buyer needs a contractor, plans and bids before closing, and the appraiser and the contractor need access to the house. Ask your agent and the buyer's lender how long their file will take, and write the dates and access into the contract. Whether a particular buyer qualifies is a question for that buyer's lender. How an owner-occupant and an investor read the same house differently is in selling to an investor vs. an owner-occupant.

Permits and historic review change the scope

A full remodel is permit work, and so is undoing old work that was never permitted. Before you price a remodel, look up what the city has on file for the house; how is in permit history: how to look yours up.

Historic houses add a second review. Claremont's Cultural Resources Preservation Ordinance, in the version the city posts with its historic preservation program, says no person may proceed with demolition, alteration or relocation of a cultural resource, or new construction affecting one, without first obtaining a Certificate of Appropriateness from the city's Architectural and Preservation Commission, and that approval is required even when no other city permit is. The ordinance defines alteration as physical change to the exterior that may significantly affect character-defining features, including additions, but not ordinary maintenance and repairs. So a new kitchen inside a listed Claremont bungalow and a second-story addition on the same house are very different projects. Pomona's Lincoln Park, Wilton Heights and Hacienda Park historic districts carry preservation rules on exterior changes too; check with the Pomona planning division before you design anything visible from the street.

If you do the remodel yourself

You become the project manager. The Contractors State License Board recommends checking each contractor's license status online and getting at least three written bids, and says a licensed contractor must give you information about its insurance in the written contract. You also carry the house through design, permits, construction and a listing: the mortgage, property tax, insurance and utilities for every one of those months. The bids are also your check on any offer; how to put them side by side is in repair estimates vs. an offer's deductions.

When is a house not worth remodeling before a sale?

When the remodel would cost more, in money and months, than it adds to the sale price. That tends to happen when the list mixes failing structure or systems with dated finishes, so you are paying for the invisible work and the visible work at once; when historic review or legalizing old work stretches the timeline; when you are an heir, trustee or owner out of the area who cannot oversee a job; or when the house is vacant and every month adds risk. A house that is not safe to live in raises its own questions, covered in selling an uninhabitable house, and a house whose real problem is underneath is covered in selling a house with foundation movement.

When remodeling and listing nets more

• The house is sound, so the remodel is finishes and layout rather than structure and systems.
• The finished house would compete with renovated sales on the same streets, not with a different, pricier market.
• You have the cash, the time and someone local to manage licensed contractors and permits.
• No historic review or legalization stands between the plans and the permit, or you have already cleared it.

A narrower version also wins often: fix only what moves the house from C6 to C5, so ordinary financed buyers can reach it, and leave the remodel to them. When either is the case, the written recommendation says to do the work and list, and you are introduced to a designated local expert, an independently licensed California agent who works your neighborhood.

What this looks like in practice

These are the kinds of files that come in, described without names or figures.

• A Claremont Village bungalow on the city's historic register with original wiring and plumbing, where the family wants to know what review a new owner would face before choosing a path.
• A post-war ranch house north of Foothill Boulevard with an original panel, galvanized supply lines and a garage converted without permits.
• A Chino Hills planned-community house in original condition, inherited by siblings who live out of state and do not want to run a remodel.

Getting both numbers

Nothing needs to be started, bid or cleared before the walkthrough. You get an as-is cash offer from independent buyers and investors, with each part of the work valued on its own line, and an open-market read on the house as-is and remodeled. The open-market read is a preliminary estimate, not an appraisal; an automated estimate cannot see the condition at all, and a CMA usually assumes a typical one. When remodeling and listing nets more, the written recommendation says so. Start on the fire, water and repair-heavy houses page or call (909) 498-3977. There is no cost and no obligation to get the two numbers and the written report.
