Holding Cost Calculator
A holding cost calculator estimates the monthly and total cost of owning a property during a hold period. It helps test timeline risk, but it does not verify sale timing, refinance timing, repairs, insurance, taxes, or market demand.
Estimates are based on your inputs and assumptions. DealSharp does not provide financial, investment, legal, tax, or lending advice.
Run the number, then pressure-test the assumptions.

Use this page to understand the metric directionally, then compare it against financing, reserves, repair risk, cash flow, and your own constraints.
Use this working calculator as a starting point, then run the full deal in DealSharp when you need more inputs, side-by-side scenarios, and risk context.
Total holding cost = monthly holding cost x hold months
If monthly debt service is $1,300, taxes are $350, insurance is $150, utilities are $250, HOA is $0, misc costs are $200, and hold period is 6 months, estimated total holding cost is $13,500.

How to read this number
The useful move is not treating one number as a final answer. Use it to decide which assumptions deserve more review, then compare the result against cash flow, financing, reserves, repair risk, and your own constraints.

FAQ
Are holding costs only for flips?
No. They also matter for BRRRR projects, vacant rentals, delayed lease-up, and refinance timelines.
