What’s your backup plan when your flip goes over budget?

A contractor finds an issue behind the walls. Materials cost more than expected. The project takes an extra month. Suddenly, the capital that was supposed to carry the project to completion is running low.
That’s why I believe having a funding strategy is just as important as finding the right deal.
Depending on the investor’s qualifications and business structure, business lines of credit, 0% introductory APR business credit cards, business loans, or revenue-based funding may provide additional capital for rehab expenses, holding costs, or future opportunities. The key is understanding the terms and having a repayment strategy before using the funds.
For the experienced flippers here, what’s your go-to backup plan when a rehab goes over budget: cash reserves, a line of credit, additional financing, or something else?
Cash reserves.
I have worked in all sorts of real estate long enough to know: when you need money, no one will give it you. Or more realistically, they will lend to you at terms that you might be lucky to break even. This holds true for the large retail operators I have worked for, syndicators, pref equity, etc.
Answering from the other side of it, since I run the construction company that creates the overrun you're describing. Full disclosure on the bias that comes with that.
The question treats an overrun as a financing problem, and Evan's answer is right for the version that actually is one. But most of the overruns I watch happen are a sequencing problem wearing a financing costume, and the difference matters because one of them you can fix for free.
Here's the shape of it. On almost every job, the bad news exists early and the money runs out late. The thing behind the wall is discovered during demo, in week one or two. The budget doesn't actually break until finishes, in week seven or eight, because that's when the expensive material lands. So there is usually a five or six week gap between when the problem becomes knowable and when it becomes painful, and what people do with that gap determines whether they need your line of credit at all.
If you know in week two that the job is fifteen thousand heavier, you have real options. Cut finish level in rooms that don't drive the comp. Drop a scope item entirely. Go back to the seller if you're still in a period where that's possible. Renegotiate the schedule. All of those are free or cheap.
If you find out in week seven, every one of those options is gone, because the material is already bought and the labor is already committed, and the only thing left is expensive money. That's the moment most people are in when they start looking at a 0% intro card, and the reason they're looking is exactly the reason it's dangerous.
So the backup plan I'd actually build:
Front-load discovery. Do all destructive investigation and all mechanical rough-in before you spend a dollar on anything decorative. Open the walls where you suspect, scope the sewer, pull the panel cover, get under the floor. Get a revised number at the end of that phase and treat it as the real budget. The cash you have not yet spent on cabinets is your most flexible reserve and it costs nothing to hold.
Ask your contractor one question every Friday: based on what you've seen so far, is the final number still the number. Most GCs know a job is going over a couple of weeks before the owner does, and plenty won't volunteer it because the conversation is unpleasant and they're hoping to make it back somewhere. That's not usually malice, it's avoidance, and I'd include my own trade in that. Asking directly and in writing changes what gets said.
Know in advance what you'd cut, and never cut behind the drywall. Under pressure people cut the mechanical because the visible items feel like they have more defensible price tags. Backwards. You can change a countertop in year three for a few thousand dollars. You cannot change a drain line in year three without undoing finished work, and the buyer's inspector will find it either way.
And yes, reserves. But I'd size them against the scope rather than as a flat percentage. A cosmetic refresh on a 2005 house and a full gut on a 1948 house do not carry the same distribution of outcomes, and a flat ten percent contingency prices them identically, which is how the older house eats people.
Genuinely useful thread question. The honest version of the answer is that the best backup plan is a shorter feedback loop, and most people are buying capital to compensate for information they could have had for free in week two.
What you're talking about is what I call unforeseen conditions . In construction, especially rehabs, you can open something up and find an issue nobody could see during the walkthrough. That's why I always leave room in the budget for unforeseen conditions and deal with the must-do items first. The real trick is knowing which surprises deserve the money and which ones don't....
