đĄPractical Holding Cost Tips
This is a house flip calculator for holding costs. Materials arenât usually the biggest expense during a house flip. Time is. Sure, have a great design plan and the best contractor money can buy. But wait two additional months for a permit revision/appraisal and those days silently eat away at your profit margin. Thatâs why we created this flip holding cost calculator⊠To shed some light on this hidden drain.
Once you know how much money it eats each day and how much it add up to in total, youâll be able to understand exactly what happens when timeline slips. Most investors gets laser-focused on their renovation budgets and acquisition costs. Which is fine. Theyâre obvious expenses. Holding costs are the silent bleed that grows with every day the house sit empty or unfinished.
Why Time Costs You Money in House Flipping
The key? You must understand exactly what you are measuring before you sign a purchase agreement. Plug in your estimated hold duration, as well as your loan balance, the calculator above does all the number crunching for you. It saves you from guessing about how much interest will accrue during a stalled inspection.
You begin with some base holding months and a delay buffer. Why? Because nothing ever goes according to plan. Exterior jobs get shut down by winter weather. Buyers require extended closing periods. Permits gets lost. Model the delay as its own variable so you know real cost of uncertainty. At a daily burn rate of one hundred eighty bucks, a slip of just twenty days will cost you three thousand six hundred dollars (before listing house). Thatâs money out of your pocket for sitting around and waiting.
So whatâs it all mean? More than just feeding some numbers into a calculator, you need to know what those numbers represent. What are you carrying every month? Those are your property taxes, insurance, utilities, and (if applicable) HOA dues. Donât skimp out on utilities when doing a rehab. Theyâre much higher then what youâd pay in a fully-occupied house. Contractors has multiple tools running and rooms needing to be heated. They are also dealing with waste water.
Next, consider the interest on your financing. This calculator assumes your loan interest is treated like a flat fee each month. It depends on how much you owe and your yearly interest rate. Thereâs no consideration for complex repayment schedules, which isnât always true for hard money/bridge loans versus traditional mortgages. Bottom line: The interest keeps ticking upwards regardless of whether work is being done in site.
This tool provides a line item breakdown. Each of these fixed costs are listed individually and explains its contribution to the overall hold cost. Interest is scaled based off your loan size, and both insurance and taxes is considered flat monthly carries. The section on interpreting daily burn rate is worth reading through carefuly.
Under $75 per day? You probably have some margin. But over two-hundred? Youâre dancing on thin ice. Every delay will weaken you. At this point, you might of have to accept worse deal terms or lower prices just to break even.
Many people neglect to factor in repair/maintenance/overhead costs when making calculations. You have to mow the lawn, shovel the snow, maybe install a monitoring system so someone doesnât vandalize/squat in an empty home. Each one seem minor, yet they add up during a six month holding period. To account for this, there is fields on the calculator for recurring costs. Use them to get the complete picture.
Next time you calculate the results, take note of the âinterest shareâ percentage. This represents how much of your monthly burn is spent on financing vs. This refers to operational overhead. If itâs too large, then you may be carrying excessive debt compared to the value of what youâre expecting to resell.
At the end of the day, itâs a wake-up call. It reminds you that time is money. If you donât consider holding costs, a sweet-sounding deal will eventually turn bitter. Run those numbers upfront. Donât stretch yourself too thin and get burned. Get an idea of where you need to move forward and where you should walk away. Your ultimate objective isnât just completing the flip; itâs closing the deal while still having some wiggle room to enjoy the fruits of your labor.
Time doesnât wait for anyone, including your loan officer.
