Recalibrating After a Blown Rehab Budget on This Flip

TLDR

This flip went over budget after hidden HVAC, electrical, plumbing, framing, and wall problems surfaced. The strong buy still carried the deal, so Ross kept the finish level supported by the neighborhood comps.

What Blew the Budget

The project got stuck in phase two: mechanical, electrical, plumbing, and city inspections. Ross had bought the house from someone who had already started work. Some systems looked newer, but that did not mean they were right.

The HVAC layout made no sense, so the system moved and the ducts went through the attic. The electrical looked new but was wrong throughout. Rewiring it cost about $10,000. The plumbing had to be redone to the city sewer because the starting depth did not allow the needed slope. Small framing defects also appeared throughout the house.

The wall plan failed too. Ross expected to cover the old walls with quarter-inch drywall. A leaking roof had soaked the lath and plaster. The team had to remove it, drop the blown-in insulation, rebuild parts of the roof, hang new drywall, and replace the insulation.

What the project exposed

New-looking work is not verified work. This project shows why an investor has to inspect the systems behind someone else’s unfinished rehab.

Count Plumbing Before Pricing It

Ross explains that plumbers often price by fixture. During the walkthrough, his rough count landed at 12.5 fixture units.

He used a rough rate of $500 to $600 per fixture in that market. He then discussed the hot-water tank, faucets, tub, toilets, and other finish items. The live arithmetic is an estimate from this project, not a price sheet for every market.

The exterior line adds another layer. Ross estimated about $3,000 to dig through the yard. In places where his team also had to cut the street, connect the tap, and repair the pavement, he had paid $10,000 to $15,000. On this job, the city handled the tap connection.

The original plumbing budget was about $7,000. The walkthrough estimate had grown to roughly $12,000 to $13,000 plus finish items. That is why the fixture count belongs in the scope before work begins.

Why Moving Walls Multiplies Work

Higher-end work can tempt an investor to redesign the floor plan. Each moved wall can move plumbing and electrical too. It can also expose old parts that seemed usable while hidden.

The old cast-iron vent stack is a good example. It seemed usable until the system was filled for a water test. Then the leaks appeared and the stack had to be replaced.

On this project, the prior owner had already moved walls, and Ross continued changing the plan. In hindsight, he says he should have paid a designer to settle the layout first.

For the first- and second-time buyer homes he usually renovates, Ross tends to keep the layout. The goal is safe, livable, and appealing. Fewer layout changes mean fewer hidden systems get disturbed.

Recheck the Deal Before Cutting Finishes

After the overage, the team considered swapping hardwood for LVP and using cheaper cabinets. Ross went back to the proof in the neighborhood.

The sold homes supported hardwood, Shaker cabinets, quartz counters, and new stainless appliances. A cheaper finish package had no comparable sales behind it. Cutting the finish could have moved the house into an unproven price band.

On this flip, the purchase price left enough room for the larger rehab. The budget was beaten, but the deal still worked. The strong front-end buy absorbed the overage, so Ross kept the finish level the comps supported.

FAQ

Does the source give a contingency percentage?

No. It gives a project story, not a universal percentage or an age cutoff for houses.

What should a first-time investor take from this project?

Verify work that another owner started. Count the plumbing connections. Make layout changes explicit. Use a designer when the plan is beyond your own skill.

Should I cheapen the finishes when I am over budget?

Only if the comps support the cheaper product. Ross kept the higher finish here because the sold homes gave him proof for that level.

Why count plumbing fixtures?

In this project, the fixture count gave Ross a quick way to test the plumbing allowance against the actual scope. Pricing methods still vary by plumber and market.
