Buying a second home in Miami | Photo by Nadia Bouzid
If you want your Miami apartment for January, February, and March, those months cannot also appear as rental income in the calculation used to justify buying it. That sounds obvious. It becomes less obvious when the apartment is being presented with an attractive seasonal rent and the suggestion that you can let it cover its costs whenever you are away.
I would start by crossing your dates off the calendar. Include the holidays, the visits you expect from family, and the weeks you want to keep available without committing to a trip. Then look at what is left. Those are the dates for which a rental estimate might be relevant.
Even that calendar can overstate the opportunity. An apartment can be unoccupied without being available for a tenant. You may leave your clothes and personal belongings there, want to return at short notice, or have a gap between visits that is too short for the building’s minimum lease period.
Take a hypothetical building requiring a minimum lease of 90 days. If you leave at the end of February and want to return at the beginning of April, March is vacant, but it is not a month you can simply offer for rent on its own. The restriction changes the usefulness of the apartment, regardless of what a nearby hotel charges.
This is why I would read the rental provisions before spending much time on projected income. The minimum term is only the beginning. Permitted rental frequency, tenant applications, approval procedures, and any restrictions during the first year of ownership all need checking against the actual plan. Municipal requirements need to be checked for the address as well. Permission from the condominium is only one part of the question.
A building that permits the arrangement may still be a poor fit for it. An owner wanting the same apartment ready for an occasional weekend has different needs from someone willing to commit it to a tenant for six months. Once those six months are leased, an unexpected invitation to Miami does not create a right to use the apartment.
The rental estimate should reflect that choice. A winter lease in the same building is useful evidence for a winter offering. It does not establish what the apartment could earn during a different set of months. I would want comparable furnished leases for the period actually available, with attention to their duration, floor, exposure, and condition. Asking rents deserve to be distinguished from executed leases.
Then the income needs to be reduced by the costs of obtaining it. Brokerage, management, cleaning, repairs, and intervals between occupants belong in the calculation. The annual cash requirement also needs to include association dues, property taxes, insurance, utilities, debt payments where applicable, and an allowance for work or assessments that may arise. Rent collected is not the same as money available to offset ownership.
Financing introduces another distinction. “Second home” is an occupancy category for a lender, not simply a description of the second property someone owns. Fannie Mae’s August 2023 guidance, for example, generally does not allow rental income from a second home to be used to qualify the borrower. It also sets requirements concerning personal occupancy and control of the property. The lender needs the intended arrangement before quoting financing around it.
The tax treatment has its own definitions. Personal use and rental use can affect how expenses are allocated and deductions limited. Family stays may count as personal use, too. The accountant should see the same calendar as the lender and the person preparing the rental estimate. irs.gov
Distance adds a cost that rarely appears neatly in either document. Someone local needs access and authority when the air conditioning stops working, water appears beneath a sink, or the association needs to enter. Building staff may be helpful, but I would establish what they actually undertake rather than assume they manage the inside of a privately owned apartment.
None of this makes a home reserved for personal use a poor purchase. The ability to arrive without booking accommodation, stay longer, and leave belongings in place has value. It should be valued honestly, including the income forgone to preserve that freedom.
I would want two versions of the annual budget: one with rental income supported by the dates and restrictions, and one without it. The second shows the commitment if a tenant does not materialize, a lease falls through, or you decide to spend more time here.
The apartment may still be worth buying. But if the calculation only works when you surrender the months you most wanted to use it, the purchase needs reconsidering. The calendar will have identified the problem before the contract makes it yours.
