Lease Option Miami Seller Guide: Underwriting Rent-to-Own in 2026

Last updated: August 2026

A lease option gives an occupant the right, but not the obligation, to buy your Miami-Dade property at a fixed price inside a fixed window while they rent it from you. A lease-purchase obligates them to buy. Either way you sign two contracts at once, and the purchase right carries almost all of the risk. The exposures that matter: the IRS may treat the arrangement as a sale rather than a lease; a Florida court may treat it as an equitable mortgage and require you to foreclose rather than evict; your due-on-sale clause sits outside the federal safe harbor, which covers only a leasehold of three years or less with no option to purchase [1]; vacating can cost you your homestead exemption and Save Our Homes cap; and your homeowner policy is written for a property you occupy. This is a narrow instrument, and a conventional sale is usually cleaner. Review any structure with a Florida real estate attorney and a CPA.

The two structures, and the money that moves

A lease option is a lease plus a separate option agreement. The occupant pays option consideration for the right to buy at a stated price by a stated date. If they do not exercise, you keep the fee and the property. Your cost is time, plus the spread if value rises above a strike price you locked years earlier. A lease-purchase instead binds the occupant to close, which sounds stronger but means a specific-performance claim worth whatever the counterparty can pay, in litigation you fund.

Two mechanics do the work. Option consideration is a lump sum paid up front, non-refundable and credited against the price at closing. Rent credit is a portion of each monthly payment applied to the price only if the option is exercised.

Hypothetical for illustration only, not a market figure: a $900,000 strike price, a $27,000 non-refundable option fee equal to 3 percent, a 24-month term, rent of $5,500 with $500 credited toward the price. Exercise at month 24 and the occupant closes with $39,000 applied. Walk away and you have collected $27,000 plus full rent and still own the asset. The tension is structural: the larger the fee and the heavier the credit, the more this looks like equity accumulation rather than rent, which is the pattern that draws recharacterization.

Tax risk: the IRS may call it a sale

Publication 527 states that if the rental agreement gives your tenant the right to buy your rental property, the payments you receive are generally rental income [2].

Substance controls, not labels. The IRS decides whether an agreement in the form of a lease is in substance a conditional sales contract from the parties' intent and the facts, including whether the option price is nominal compared to the property's value when the option may be exercised, whether portions of the payments are designated as an equity interest, and whether payments materially exceed fair rental value [3].

If it is recharacterized you did not collect rent. You made a disposition, reportable under the installment method unless you elect out [4], with the fee and credits folded into proceeds and interest imputed on the deferred balance. That reaches returns you have already filed.

Section 121 is the second clock. To exclude gain on a main home you generally must have owned and used it as a residence for at least 24 months of the 5 years ending on the sale date, up to $250,000 of gain, or $500,000 on a joint return [5]. A 36-month option on a home you already vacated can push the closing outside that window. Depreciation recapture is a separate CPA question.

The Florida risk that matters most: equitable mortgage

Florida Statutes 697.01 provides that instruments conveying property with the intention of securing the payment of money are deemed mortgages [6]. Florida courts look through form to function. If a court concludes the occupant acquired an equitable interest and the paperwork is disguised financing, eviction is not the remedy.

Section 702.01 states that all mortgages shall be foreclosed in equity [7]. That is the practical difference. A residential eviction for nonpayment starts with a written demand and a default continuing 3 days, excluding Saturdays, Sundays, and legal holidays [8]. A foreclosure is a full civil action with pleadings, discovery, judgment, and a judicial sale, the occupant in possession throughout.

The facts that push a court toward that reading are the ones that make the deal appealing: a large option fee, heavy rent credits, a long term, and an occupant paying taxes and repairs.

Where Chapter 83 stops protecting you

Florida's landlord-tenant law has its own off-ramp. Section 83.42 excludes from Part II of Chapter 83 occupancy under a contract of sale of a dwelling unit in which the buyer has paid at least 12 months' rent, or at least 1 month's rent plus a deposit of at least 5 percent of the purchase price [9]. A meaningful option fee plus two years of payments can move the occupancy outside the statute that supplies your summary remedies. Ask your attorney where your documents sit against that line.

Due-on-sale exposure if you still carry a mortgage

The Garn-St Germain Act exempts certain transfers from due-on-sale enforcement on residential property of fewer than five units, including a leasehold interest of three years or less not containing an option to purchase [1]. A lease option contains one by definition, so you are outside the exemption. Whether a servicer acts is a separate question, but the note is accelerable on its terms and you have no federal shield.

Homestead, Save Our Homes, and the cost of vacating

Renting all or substantially all of a dwelling previously claimed as homestead constitutes abandonment for tax purposes under Florida Statutes 196.061 [13]. Save Our Homes caps annual assessment increases at the lower of 3 percent or the change in the Consumer Price Index, and once the exemption is lost the property is assessed at just value as of January 1 of the next year [10].

Claiming an exemption you no longer qualify for is expensive. The Miami-Dade County Property Appraiser states that an owner can be back taxed for 10 years of exempted taxes, plus 15 percent interest per annum and a penalty of 50 percent of the taxes exempted [11]. Portability has separate rules and deadlines.

Insurance changes the day you move out

An owner-occupied policy is not written for a property you no longer occupy, and a landlord or dwelling policy changes contents, loss-of-use, and liability terms. Occupancy is material on the application and carriers examine it at claim time. Notify your carrier in writing and have the new policy in hand before possession transfers.

What a seller should require

Documents drafted by a Florida real estate attorney, the lease and the option as separate instruments.
A recorded memorandum of option, which clouds title for the term.
Substantial, genuinely non-refundable option consideration, held per your attorney's escrow instructions.
A verified financing path with dated milestones in writing from a lender, not a stated intention to qualify later.
An independent basis for the strike price rather than a number picked to make the deal work. Start with a [listing valuation](/listing-valuation).
Written allocation of taxes, insurance, HOA assessments, and maintenance, with a threshold above which you approve repairs.
Default and cure mechanics stress-tested against the eviction versus foreclosure question, and CPA sign-off on how every dollar is reported before the first one moves.

When a conventional sale is the better answer

Most Miami-Dade properties that are correctly priced, prepared, and exposed do not need this structure. A lease option is a workaround for a gap between what the market will pay today and what the seller wants, and it converts a clean disposition into a multi-year credit and litigation position you underwrite personally. If the motivation is price, test the price. My [seller process](/sell-your-miami-home) starts with what the property clears at now, the number that decides whether a two- or three-year option is worth these risks.

I am a licensed Florida real estate agent, not an attorney or a CPA. Drafting contract language for you would be the unlicensed practice of law, which Florida Statutes 454.23 makes a felony of the third degree [12].

Frequently asked questions

Does a lease option affect a Miami-Dade homestead exemption?

If you vacate and rent all or substantially all of the property, Florida Statutes 196.061 treats that as abandonment of the homestead for tax purposes [13]. Losing homestead ends the Save Our Homes cap and the property is reassessed at just value the following January 1 [10].

If the occupant stops paying, can I use a standard eviction?

Not necessarily, and that is the central risk. Florida Statutes 697.01 deems instruments made to secure payment of money to be mortgages [6], foreclosed in equity under 702.01 [7]. Section 83.42 separately removes occupancy under a contract of sale from Part II of Chapter 83 once the buyer has paid at least 12 months' rent, or 1 month's rent plus a 5 percent deposit [9]. Your attorney should tell you which remedy your documents leave you.

Is the option fee taxable when I receive it?

That depends on how the arrangement is characterized, which is a CPA question. Publication 527 says payments under a rental agreement that gives the tenant the right to buy are generally rental income [2], but the IRS applies a substance test that can treat a purported lease as a conditional sale instead [3].

Is this common in Miami-Dade?

It is a niche structure, not a mainstream one, and it usually reflects a pricing or financing gap rather than a preferred outcome. Most sellers are better served by a conventional sale. See the [FAQ](/faq).
