In this hypothetical $300,000 rental purchase, $2,800 monthly rent leaves only $421 a year after operating costs, mortgage payments, and a replacement reserve. A lower rent or major replacement turns the result negative. This is a demonstration of the review process, not an available property or a forecast of Southwest Florida returns.
The Hypothetical Purchase
All inputs are illustrative assumptions chosen for this example, not a listing, appraisal, rent forecast, or loan quote. The interest rate is not a current advertised offer. Replace every input before evaluating a real address.
| Input | Assumption | What to verify |
|---|---|---|
| Purchase price | $300,000 | Comparable sales, condition, and negotiated terms |
| Down payment and loan | $75,000 down; $225,000 loan | 25% down; lender terms and required reserves |
| Financing | 6.5% fixed; 30 years | About $1,422 monthly principal and interest; taxes and coverage budgeted separately |
| Scheduled rent | $2,800/month | Address-specific competing rentals and achievable lease terms |
| Closing costs and opening cash reserve | $9,000 plus $10,000 | Separate from the down payment; no initial renovation assumed |
| HOA and owner-paid utilities | $0 assumed | No association; tenant pays utilities and routine lawn care under this hypothetical lease |
Where the Annual Rent Goes
Amounts are rounded to whole dollars for display; totals use unrounded calculations. Management is 8% of collected rent after a 5% vacancy allowance. Maintenance and leasing are separate annual dollar budgets.
| Line Item | Annual Amount | Treatment |
|---|---|---|
| Scheduled rent | $33,600 | $2,800 multiplied by 12 |
| Vacancy allowance | $1,680 | Reduces collected rent to $31,920 |
| Management | $2,554 | 8% of $31,920; contract fees may differ |
| Property taxes | $4,500 | Replace with a post-purchase parcel estimate |
| Insurance budget | $3,600 | Illustrative combined rental-use coverage budget; obtain all necessary quotes including flood |
| Routine maintenance | $1,680 | Assumed spent during the year; not a capital replacement reserve |
| Leasing and turnover fees | $600 | Separate allowance; replace with the manager's full fee schedule |
| Operating income before debt and reserves | $18,986 | Collected rent less the five operating expense lines above |
| Mortgage principal and interest | $17,066 | 12 amortizing payments; does not include escrowed expenses |
| Replacement reserve | $1,500 | Cash retained for future capital work, not spent in the base case |
| Cash remaining after replacement reserve | $421 | About $35 per month before income taxes and any costs outside these assumptions |
What Happens When the Assumptions Change?
Each scenario changes one input from the base case. Management changes with collected rent; other operating budgets and financing stay fixed. These are stress tests, not predictions.
| Scenario | Annual Cash Remaining | Change from base assumptions |
|---|---|---|
| Base case | $421 | $2,800 rent, 5% vacancy, $1,500 replacement reserve |
| Rent falls $200/month | -$1,677 | $2,600 scheduled rent; management recalculated |
| Vacancy rises to 10% | -$1,125 | $2,800 rent; collected rent and management recalculated |
| $6,000 capital replacement | -$4,079 | Spend $6,000 instead of setting aside $1,500; do not subtract both |
How much cash would this purchase require?
The assumed $75,000 down payment, $9,000 closing costs, and $10,000 opening reserve total $94,000. The opening reserve remains cash available for ownership needs; it is not an additional annual expense. The $1,500 annual replacement contribution is a separate ongoing savings target.
Actual cash needs can include immediate repairs, prepaid coverage, escrows, lender reserves, and utility setup. Avoid counting the same prepayment both at closing and again as an extra annual cost.
Is this a good Southwest Florida rental investment?
The base case leaves very little room for error. It does not demonstrate an attractive deal simply because the cash-flow number is positive. The $6,000 replacement scenario would require cash from the opening reserve or elsewhere. A buyer should decide whether the remaining cushion is adequate before discussing hoped-for appreciation or tax savings.
For Cape Coral, Fort Myers, North Fort Myers, or Lehigh Acres, start with the same expense categories but use that property's rent evidence, tax estimate, coverage quotes, condition, and management terms. A citywide median is not a lease commitment for the house you are considering.
Why can cash flow and taxable rental income differ?
This loan's first 12 payments include about $14,551 interest and $2,515 principal. Cash flow subtracts both. Principal repayment is not a rental expense deduction, and moving $1,500 into a reserve is not the same as incurring a deductible expense.
For a separate simplified tax illustration, assume $240,000 of depreciable building basis and a full 27.5-year depreciation period calculation: about $8,727 annually. Subtracting that and the illustrated interest from $18,986 operating income produces a -$4,292 tax result before applicable limitations. Land is excluded from depreciation. This full-year illustration is not a first-year tax return; placed-in-service conventions and the actual basis change the calculation.
The paper loss does not add $4,292 to your bank account and is not automatically usable against salary. The cash cushion remains $421 under the base assumptions, regardless of the simplified tax result.
What should I replace before using this example for a real home?
Obtain a lender payment estimate, current tax projection, complete insurance quotes, manager fee schedule, association documents where applicable, and inspection-based repair and replacement budgets. Confirm who pays landscaping, utilities, pest service, and storm preparation. The $0 lines are assumptions to verify, not universal exclusions.
Request recent comparable rental evidence and ask whether each number represents asking rent or a signed lease. Re-run the downside scenarios with a realistic vacancy period and major repair exposure before proceeding.
