How to Budget the First 90 Days of STR Ownership

The first 90 days of STR ownership often consume cash before the property reaches normal performance. Build a weekly cash calendar for closing, setup, launch, and early operations rather than assuming the first month will resemble a stabilized annual forecast.

Separate cash categories

Show closing cash, furnishing and repairs, prepaid costs, operating reserves, and contingency separately. A reserve is money that remains available after launch expenses are paid. Calling an unspent furnishing allowance a reserve overstates the protection available for a slow opening.

Model the opening date honestly

Set milestones for possession, inspections, work completion, licensing, insurance, photography, listing activation, and the first guest. Some steps depend on others. An opening delayed by two weeks can add debt service, utilities, and contractor costs while removing bookable nights.

Use a weekly cash schedule

Place actual payment dates beside expected booking payouts. Include deposits, balances due, management onboarding, linen inventory, cleaning setup, and repair invoices. Distinguish a booked stay from cash available in the bank. Ask each platform and manager when funds become payable and what can delay payment.

Test a slower start

Compare the planned opening with a delayed opening and lower early occupancy. Calculate the additional cash needed before the property produces a surplus. If the reserve cannot cover the downside case, change the setup scope, financing, purchase price, or acquisition decision before closing.

Action checklist

Should I use a universal STR reserve percentage?

Use the actual property costs, opening timeline, debt service, and downside scenario. A percentage can be a preliminary screen, but it is not a complete cash budget.
