Yes, you can mortgage property in Monopoly, but only if it has no houses or hotels on it. If a property is already developed, those buildings have to be sold back to the bank before the mortgage can happen.
Mortgaging is basically a way to turn a property into quick cash when money gets tight. The tradeoff is simple: while a property is mortgaged, it does not collect rent, and you have to pay the mortgage amount plus interest to unmortgage it later.
That makes it a useful move in a pinch, but not one to use lightly. If you want to avoid getting stuck with dead money on the board, it helps to know exactly when mortgaging makes sense and what it changes for rent, trades, and long-term strategy.
Can you mortgage property in Monopoly?
Yes. In the standard rules, any property can be mortgaged as long as it has no buildings on it. If the property is part of a color group that has houses or a hotel, you must first sell those buildings back to the bank.
That means the usual sequence is:
- Sell houses or hotels if the property group has them.
- Mortgage the unimproved property.
- Use the cash to pay a debt, stay in the game, or set up a stronger trade or building plan.
This is why players often mortgage weaker, non-core properties before they touch their best color groups. It keeps your strongest income spots intact for as long as possible.
What has to happen before you mortgage a property?
The key restriction is simple: the property must be undeveloped. No houses, no hotel.
If you own a full color set and one property in that set has a building on it, the whole group usually has to be treated carefully before you borrow against any of them. A mortgaged property also stops you from collecting rent on that space, so it is best used as a cash emergency tool, not a first choice.
| Situation | Can you mortgage it? | What to do first |
|---|---|---|
| Unimproved property | Yes | Nothing else is required |
| Property with houses | No | Sell the houses first |
| Property with a hotel | No | Sell the hotel first |
| Mortgaged property in a trade | Yes, but the mortgage stays attached | Make sure both players understand the debt |
If you are sorting out a cash crisis, the same logic applies to a broader debt situation too. The order matters, and that is covered in more detail in Monopoly bankruptcy.
When should you mortgage in Monopoly?
Mortgaging is usually a defensive move, but sometimes it is the right move. The best time to mortgage is when the cash you get back does more for you than the rent income you’re giving up.
Good reasons to mortgage include:
- Paying an immediate debt so you do not go bankrupt.
- Keeping a strong color group alive while you raise money elsewhere.
- Funding houses on a set that is already likely to pay off.
- Buying time until you can trade or collect enough rent to recover.
Bad reasons to mortgage include borrowing against your strongest income property too early or mortgaging so many spaces that you leave yourself with no real income. That is how players end up selling houses at a loss later and falling behind anyway.
A practical cash-raising order
If you need money fast, this is the safest order to follow in most games:
- Sell houses or hotels first if the rules and your board state force you to.
- Mortgage non-core properties next — usually the ones outside your main color group.
- Keep your best rent-producing set intact if you can.
- Only unmortgage later when you have enough cash cushion to survive another bad roll.
That order is not just about surviving one turn. It helps avoid the common mistake of breaking up a winning set just to solve a short-term cash problem.
What happens to rent, trades, and ownership?
A mortgaged property does not collect rent while it is mortgaged. If someone lands on it, they do not pay rent for that space until the mortgage is cleared.
Ownership does not disappear, though. The property still belongs to you, and in many standard rule sets a mortgaged property can still be traded or transferred. If that happens, the mortgage obligation usually stays attached to the property, so the new owner inherits the problem along with the deed.
That is the detail many casual players miss: a mortgaged property is not worthless, but it is a burden. It can still matter in a trade, but both sides should be clear on what cash is still owed.
If you are trying to avoid losing everything after a bad turn, the timing of a mortgage often decides whether you limp away or get eliminated. That is why the broader payoff rules in when you cannot pay in Monopoly are worth understanding too.
How unmortgaging works, including the 10% fee
To unmortgage a property, you pay back the mortgage amount plus 10% interest. The 10% is charged on the mortgage value, not on the original purchase price.
Example: if the mortgage value was $180, you pay $198 to clear it. You are not paying 10% of what the property originally cost; you are paying 10% of the money the bank loaned you.
That small difference matters, especially with expensive properties. It is easy to assume the fee is tiny, but once you add it up across several properties, it can eat a surprising amount of cash.
When it makes sense to stay mortgaged a little longer
If paying off the mortgage leaves you too thin to survive another turn around the board, it is often smarter to wait. The best time to unmortgage is when you can do it without immediately putting yourself back into a cash crunch.
A simple rule of thumb:
- Unmortgage first when the property is part of a strong, likely-to-pay color group.
- Wait if the property is not earning much and your cash reserve is already low.
- Do not clear a mortgage if that will force you to mortgage something else right away.
Digital editions and house-rule confusion
In tabletop Monopoly, players usually treat mortgaging as something you can do whenever the rules allow it during normal play. Some digital versions and board-game apps are less flexible and only let you mortgage on your turn or through a specific menu.
So if someone says, “You can’t do that now,” the first question is whether you are playing the classic tabletop rules or a digital implementation with built-in limits. The rule itself may be the same, but the software can restrict when the option appears.
House rules also cause trouble. Some groups allow friendly shortcuts, while others are strict about when mortgages can happen, how trades are handled, and whether you can build immediately after unmortgaging. If you are not sure, settle it before the game starts.
Common mistakes to avoid
- Trying to mortgage a property with buildings on it. Houses and hotels have to be sold first.
- Forgetting the 10% fee. The unmortgage cost is not just the original loan amount.
- Using your best property too early. Mortgaging a core income space can weaken your whole position.
- Assuming a mortgaged property is out of play forever. It can still be traded, and the mortgage can still be cleared later.
- Mixing tabletop rules with app behavior. Some digital versions handle timing differently.
Quick checklist before you mortgage
- Does the property have houses or a hotel on it?
- If yes, have those buildings been sold back first?
- Will mortgaging this property leave your best rent set intact?
- Do you actually need the cash now, or can you sell something else first?
- If you plan to unmortgage later, can you afford the 10% fee without going broke again?
If the answer to the last question is no, it is usually better to leave the property mortgaged a little longer.
Frequently asked questions
Can you mortgage property at any time in Monopoly?
In classic tabletop rules, mortgaging is generally allowed when the property is unimproved. Some digital versions narrow that timing and only let you do it on your turn.
Can you build on other properties if one property in the color group is mortgaged?
No. If a property in a color set is mortgaged, you need to clear that mortgage before building normally in that group.
Does a mortgaged property still count as yours?
Yes. You still own it, but it does not produce rent until it is unmortgaged.
Do you pay 10% of the purchase price to unmortgage?
No. The 10% is based on the mortgage amount, not the original purchase price.
Can a mortgaged property be traded?
Usually yes, and the mortgage generally stays tied to the property unless your version’s rules say otherwise. Make sure both players agree on who is responsible for clearing it.
Once you know the basic rule, mortgaging in Monopoly is less confusing than it first looks. The main idea is simple: only unimproved property can be mortgaged, you lose rent while it is mortgaged, and it costs a little extra to buy it back later. Used carefully, it is a useful emergency tool. Used carelessly, it can weaken your strongest position and make a bad turn even worse.
