Lease Options and Master Leases: How the Structures Work

Both structures answer the same question: how do you control a property you cannot or do not want to buy today?

TL;DR: A lease option is a lease plus a separate right to purchase at a fixed price within a fixed window — you control one property and you decide later whether to own it. A master lease is a lease over a whole asset that lets you sublet it and keep the spread, usually with a purchase option attached. Both need the option consideration, the strike price and the exercise mechanics in writing, both are exposed to the owner's underlying mortgage, and both are treated as a sale by some lenders and some state statutes regardless of what you call them.

Lease option: the two agreements

A lease option is always two documents, and people who merge them into one create most of the litigation in this area.

The lease is an ordinary tenancy: term, rent, who repairs what, default remedies.

The option is a separate, unilateral right to buy — you may, the seller must. It specifies the option consideration you pay for the right, the strike price, the exercise window, how notice is given, and what happens to any rent credit.

Term	What it does	Typical range
Option consideration	Buys the right; non-refundable	1–5% of price
Strike price	Fixed at signing, or by formula	Set at or above today's value
Option term	How long you may exercise	12–36 months
Rent credit	Portion of rent applied to price	$0–$400/month
Assignability	Whether you can sell the option	Negotiated

The economics are simple. You pay a small non-refundable amount for the right to buy at a fixed price. If the property rises above the strike, you exercise or sell the option and capture the difference. If it does not, you walk and your loss is capped at the consideration plus any above-market rent.

Where lease options actually go wrong

The rent credit is not equity. Buyers routinely believe two years of credits are money in the property. They are a discount on a purchase that may never happen, and they disappear if the option lapses.

Financing was never lined up. The most common failure is not a market move — it is arriving at month 24 unable to qualify. If you intend to exercise, the qualifying work starts in month one, not month twenty. Run the numbers you will have to clear on the mortgage payment calculator before you sign, not after.

The owner stopped paying the mortgage. Your option is worthless if the lender forecloses. Require evidence the underlying loan is current, and an authorisation letting you verify it directly with the servicer.

A court recharacterised it as a sale. Heavy option consideration, large rent credits, an above-market rent and a below-market strike price together look like an instalment sale wearing a lease costume. Some states will treat it as one, which converts your eviction remedy into a foreclosure and drags in the same forfeiture questions as a land contract. Keep the two agreements genuinely separate and the economics genuinely optional.

It was never recorded. Record a memorandum of option. An unrecorded option does not stop the owner selling to someone else, and your remedy afterwards is a lawsuit rather than a property.

Master lease: renting the whole asset

A master lease takes the structure up a level. You lease an entire property — a small apartment building, a mobile home park, a self-storage facility — from the owner at a fixed amount, then operate it and keep whatever you produce above that number.

The owner gets a guaranteed cheque and no operations. You get control of the income stream without a down payment, a loan, or a closing.

A worked example on a 12-unit building:

Line	Amount
Gross rents at signing	$9,600/mo
Master lease payment to owner	$7,000/mo
Operating expenses you carry	$2,200/mo
Spread at signing	$400/mo
Gross rents after 18 months of lease-up and turns	$11,400/mo
Operating expenses	$2,400/mo
Spread after	$2,000/mo

The $400 opening spread is the tell. Master leases are not cash-flow plays on day one — they are value-creation plays where the operator believes the asset is under-managed. If there is no operational upside, there is no deal, because you have taken the risk of ownership without the appreciation.

Attach a purchase option at a strike based on today's income, and the improvement you create accrues to you rather than the seller. Without that option you are doing unpaid asset management.

When a master lease beats buying

• The seller wants their price and you do not agree with it — you can pay their price later, against income you created.
• The asset will not finance today. Poor occupancy or missing financials kill a loan application; 18 months of operating history you produced fixes both. This is a common route into mobile home parks and small self-storage.
• You have operating skill and limited capital, which is the profile the structure was built for.

And when it does not: a stabilised, well-run asset. There is nothing for you to add, so the owner's price already reflects the income, and you are absorbing management risk for a thin spread.

What has to be in the master lease

Who pays for what. Routine maintenance is yours. Roof, structure and mechanicals should stay with the owner, or you are funding capital improvements on an asset you do not own.

The purchase option. Strike price, window, and how the option consideration is credited. Without it, the deal is management with extra risk.

Underlying debt covenants. Most commercial mortgages restrict leasing the entire property. Get the lender's written consent, or you have built the deal on a default.

Books and access. You need the right to inspect, and the owner needs reporting. Both go in writing.

An exit. What happens if the spread goes negative, or you cannot exercise. A term with a defined end and no personal guarantee on the whole lease payment is worth negotiating hard for.

The risk both structures share

Neither gives you title. Everything you build sits on top of somebody else's ownership and somebody else's loan, which means their problems become yours: a foreclosure, a lien, a death, a divorce, a bankruptcy. This is the same exposure that makes subject-to deals risky, arriving from a different direction.

The mitigations are the same three every time. Record your interest. Verify the underlying loan is current, in writing, from the servicer. Have counsel in the state where the property sits read the documents before you sign.

Final take

Lease options and master leases buy control cheaply and defer ownership. The trade is that you are exposed to an owner whose behaviour you do not govern, and to a body of state law that sometimes disagrees about what you have actually signed. They reward operators — people who can raise income or fix a problem inside the option window. For everyone else, conventional or seller-financed acquisition is simpler and safer.
