How much cash do you keep available after closing on a flip?

Question

One mistake I see investors make is putting so much capital into the purchase and initial rehab that there’s very little liquidity left when something unexpected happens.

A contractor goes over budget. Materials cost more than expected. The project takes longer. Or another good deal comes up before the current one sells.

That’s why I think having access to capital before you actually need it is important.

Depending on the situation, that could mean keeping cash reserves available or having access to business funding such as a business line of credit, 0% APR business credit cards, or other financing options instead of using every dollar of your own cash.

Of course, the numbers on the flip still have to make sense, and you should only leverage what you can realistically afford to repay.

For the experienced flippers here how much liquidity do you like to keep available after you close on a property?

When I started and wasn’t making much money there was a lot of credit card roulette for unexpected expenses both with rehabs and LTRs. Now that I’m established I budget for the unknown mentally but don’t have an emergency fund anymore.

Nicholas, I agree with the core point here: a flip can be profitable on paper and still become dangerous if the investor runs out of liquidity halfway through the project.

I would not use a fixed reserve percentage for every deal. I’d size the reserve around the actual risk in the project: rehab scope, age of the property, contractor reliability, financing terms, expected hold time, and how much margin exists if the resale takes longer than planned.

I’d also be careful about counting available credit as the same thing as cash. A line of credit can be useful, but if the project runs long or the market shifts, revolving debt can become expensive quickly.

From the tax side, I’d keep all rehab and carrying costs tracked cleanly by project. A flip is generally active business activity, and many of those project costs may need to be capitalized into the deal rather than treated like ordinary current deductions.

If the flip business becomes consistently profitable, I’d also evaluate whether an S-Corp makes sense based on the profit level, activity volume, payroll requirements, reasonable compensation, and the overall structure.

There can also be a powerful planning opportunity if you combine active flip income with rental real estate. Depending on the participation rules, depreciation, entity structure, and whether the rental losses are actually usable, those losses may be able to offset active real estate income. In the right fact pattern, that can reduce taxable income very significantly, potentially even to zero, but it has to be planned correctly.

The mistake I see is investors optimizing for maximum leverage at closing instead of maximum survivability through the entire project.

Feel free to DM me, I’d be happy to send over a few resources that might help with flip underwriting and downside planning.

I think about this in layers rather than one magic reserve number.

First is the rehab contingency — money I hope not to spend. Then enough carrying cost to survive a project taking longer than expected. And then separate business liquidity so one ugly project doesn’t start starving everything else.

A line of credit is a great backstop. I just don’t like underwriting a deal that only survives if I have to use it.

Especially with Rochester’s older housing stock, one sewer line, electrical surprise, furnace or delayed closing can change the conversation pretty quickly.

If one surprise puts the project in distress, the problem probably started with the basis, not the reserve.

@Nicholas Floyd, I agree with you on keeping liquidity available. I’ve seen how much easier a project is to manage when you still have some breathing room after closing instead of putting every dollar into the deal upfront. For me, the amount depends on the project, but I like having enough set aside for rehab surprises, carrying costs, and the timing between contractor payments and lender draws. Even when the overall numbers look good, those timing gaps can still put pressure on the project if you are too tight on cash. I like the way you’re looking at business credit as a backup tool instead of something the deal has to depend on.

That makes a lot of sense. Once you’ve been through enough projects, you get better at anticipating the “unexpected” expenses. I also think there’s value in having access to a business line of credit or other capital as a backup, even if you don’t need to use it. That way you’re not scrambling when something comes up. Sounds like experience has really changed how you manage your projects.

my best clients I fund their BRRR and flips have their own rehab money they dont borrow it. reduces the interest rate burden I like those deals

with my funding mechanism it allows them to scale pretty nicely and really control the deal not worrying about inspections and paying for draws and all the time and effort coordinating the draws.. Highly efficient in my mind.

Exactly. I look at a line of credit as a safety net, not something that should be required for the deal to work. The numbers still need to make sense on their own, with enough cash reserved for rehab surprises and carrying costs.

Where business credit can help is giving an investor another layer of liquidity without draining all of their cash upfront. The goal should always be to use leverage responsibly and only take on what the project can realistically support.

Great points, Ashish. I especially agree that available credit shouldn’t be treated as a replacement for cash reserves. I look at business credit and lines of credit more as a secondary liquidity tool—something available for unexpected rehab costs, carrying expenses, or timing gaps without tying up every dollar of cash.

The key is making sure the numbers work before taking on the leverage and only using what the project can realistically support. I also like your point about structuring the reserve around the actual risk of each deal instead of using one percentage across the board. That’s a much smarter way to look at it.
