Reading the number
Holding costs are the silent killer of flip profit. Every month a project takes longer than planned eats $4,000–$8,000 of expected profit on a typical project.
Vacant property insurance costs more than standard policies. Utilities run higher than you'd think (water, heat, and electricity for power tools). Build a buffer — flip projects almost always run longer than initial schedule.
EveryCalc calculators are designed for fast, practical estimates with transparent inputs and no required account. We use plain formulas, visible assumptions, and related tools so visitors can check the result from more than one angle.
Results are informational only. For financial, tax, legal, medical, construction, or other high-impact decisions, verify the output against primary sources or a qualified professional.

How this calculator works
What this page estimates
This Flip Holding Cost Calculator is built to give a quick, browser-based estimate for flip holding cost. Build the monthly carry for a flip project — loan interest plus property tax, vacant-property insurance, utilities, HOA, and any other monthly costs — and total it across the planned hold. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the flip holding cost result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this flip holding cost estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.
How to Use

- Enter the loan balance and rate during the rehab period.
- Enter monthly tax, insurance, utilities, HOA, and other carry items.
- Read total holding cost — feed this into your profit-per-deal calculation.
Frequently Asked Questions
Why is vacant insurance so expensive?
Vacant homes have higher loss frequency (water damage, vandalism, fire). Standard homeowner policies usually exclude vacant properties; a builder's risk or vacant dwelling policy is required. Premiums often run 2–3× standard.
What's a typical flip hold time?
4–9 months for most cosmetic-to-medium rehabs. 9–18 months for heavy renovations or additions. Plan for the longer end — overrun is the norm, not the exception.
Do I pay interest on the full loan during construction?
On hard money: usually yes — interest on the full approved loan from day one, regardless of draw. On construction-perm loans: only on the drawn portion, but admin fees can mimic interest on the undrawn balance.
Should I include utilities even for vacant rehab?
Yes — power for tools, lights, and HVAC; water for cleaning and crews; gas if heating during cold weather. $100–$300/month is typical depending on season and project size.
