Frequently Asked Questions
What are holding costs?
Holding costs are ongoing expenses incurred while owning an investment property during renovation and sale — including loan interest, property taxes, insurance, utilities, and HOA fees.
How does interest carry work?
Interest carry is the total loan interest accumulated during the holding period. For interest-only loans, it's calculated as: loan amount × annual rate × (holding months ÷ 12).
How do holding costs affect flip profitability?
Holding costs reduce net profit directly. Every additional month of holding increases total costs. Efficient project management and realistic timelines are critical for maximizing returns.
