An Apartment in Bulgaria on an Instalment Plan with Cryptocurrency: How to Buy a Seaside Home without Banks or a Mortgage in 2026

Today, property investment is reaching a whole new level: to acquire a newly built home by the sea, you simply need to transfer part of your savings from a crypto asset into a real asset. There is no need to use conventional mortgage products or go through lengthy banking procedures.

In 2026, buying an apartment in Bulgaria on an instalment plan is particularly convenient, as the country adopted the euro on 1 January, and today's property market is full of offers that will appeal to a wide range of buyers. However, the buying and selling process involves numerous legal details, so professional support is essential. This is provided by the Sundays team: “A team of professionals ready to support you at every stage of buying property”. 

What Does “Buying an Apartment in Bulgaria on an Instalment Plan” Mean? 

An instalment plan for an apartment in Bulgaria without a mortgage allows you to divide the total amount (the property's price) into several payments according to a schedule set by the seller or developer. Unlike a mortgage loan, the purchase is not financed by a bank in this case: the sale and purchase agreement sets out all the terms concerning deadlines and the size of the initial payment.

In practice, many different arrangements are used:

1. The buyer pays part of the price when reserving the property/signing a preliminary agreement, while the remaining payments are linked to construction stages. The final portion is paid after construction is completed.
2. A fixed schedule under which the amount is “spread” over several months/years.

An instalment plan allows you to spread the financial burden over time.

Paying with Cryptocurrency: How It Works in Practice 

Following the legalisation of cryptocurrency, more and more buyers are interested in purchasing studio apartments or other properties and paying the full amount in cryptocurrency.

Is It Legal to Pay for an Apartment in Bulgaria with Bitcoin/USDT?

If the seller agrees to this arrangement and all the terms of subsequent payments have been properly documented, paying for property in Bulgaria with cryptocurrency is entirely possible. However, cryptocurrency cannot be regarded as a replacement for the country's official currency in this case; it is a means of fulfilling obligations that the parties have agreed upon in advance.

How the Transaction Works: From Reservation to the Notary

Buying an apartment in Bulgaria with cryptocurrency involves several stages:

1. Selecting and reserving the property.
2. Agreeing on the price, valuation currency, initial payment amount and future payment schedule.
3. Determining the cryptocurrency exchange rate, taking into account the point in time at which its euro equivalent is calculated.
4. Conducting a legal review of the property and documents.
5. Preparing the agreement.

The final stage is the transfer of ownership, which is formalised before a notary in Bulgaria.

Instalments + Crypto: A Combined Purchase Arrangement

When choosing newly built or resale housing, many buyers prefer a combined arrangement: the initial payment is made in cryptocurrency, while the remaining amount is paid in several tranches according to an agreed schedule. Another equally popular option is to pay part of each instalment in cryptocurrency, with its value recalculated as of a specific date.

There is no universal percentage for the initial payment in this case. All the terms are set by the seller. Most often, however, the initial payment ranges from 20-30% of the property's price, and the remaining amount is divided into several payments based on the construction period/other agreed time frames.

Fixing the price deserves particular attention, so the agreement should specify:

• the apartment's price in euros;
• the payment schedule;
• the procedure for determining the amount in cryptocurrency.

If the BTC or USDT exchange rate changes, it must be clear from the outset who bears the currency risk and which rate is used to calculate each payment.

5 Reasons to Consider Buying an Apartment with Cryptocurrency on an Instalment Plan 

A cryptocurrency payment can be convenient for buyers for several common reasons.

The main reasons are:

1. No mortgage in Bulgaria, which means there is no need to meet a bank's requirements.
2. Less dependence on bank financing. If you hold part of your capital in crypto assets, you will not need to borrow funds.
3. A clear and fixed exchange rate for payments. To reduce uncertainty when the exchange rate changes, the agreement defines the property's price in euros and the procedure for converting cryptocurrency for each subsequent bank transfer in advance.
4. The opportunity to obtain a residence permit through a property purchase. Owning one-room or two-room apartments or other apartments is a compelling reason to move to Bulgaria.
5. Potential rental income. If one-room, two-room or three-room apartments are in popular locations, they can be rented out on a short-term or long-term basis.

However, you should assess not just the payment method but the transaction's overall economics: the apartment price, instalment terms, property tax in Bulgaria and various legal risks.

Risks and How to Reduce Them 

The property catalogue offers many attractive options, but using cryptocurrency requires a more thorough review.

The main risks to consider are:

• Cryptocurrency volatility. It is therefore important to specify the apartment's price in euros in the agreement in advance and set out when the exchange rate is determined and how each payment is recalculated.
• The property's legal status. Before making the first payment, you need to check all documents (for the apartment and the land), the right to sell, encumbrances and other circumstances. This comprehensive review (due diligence) allows potential problems to be identified in good time.
• Payment security. Depending on the structure of the transaction, different payment mechanisms are considered: for example, an escrow account, through which funds are released to the recipient after predetermined conditions have been met.

To avoid external risks, the handling and supervision of all procedures should be entrusted to qualified specialists. 

A Step-by-Step Plan for Buying an Apartment in Bulgaria with Cryptocurrency

You can choose and buy property in Bulgaria on an instalment plan from a developer in various towns, including Nessebar, Sunny Beach, Sveti Vlas and others.

To do this, follow these 6 steps:

1. Define your budget and purchase arrangement. At this stage, it is important to understand the specific purpose of the purchase: holidays, renting out or living in the property yourself.
2. Choose the property. Cities, districts and residential complexes are compared against various criteria (not just price).
3. Reserve the apartment. At this stage, the key commercial terms should be fixed.
4. Conduct a legal review. All documents are checked.
5. Fix the payment terms. These range from deadlines and schedules to the consequences of breaching those terms.
6. Complete the transaction and acquire ownership.

Supporting the buyer at every stage of the transaction is an excellent way to avoid problems later on.

Residence Permits and Taxes When Buying Property in Bulgaria

Foreign nationals should remember that buying property does not give them a 100% guarantee of obtaining a residence permit. There are various grounds for obtaining such a permit, so each situation is considered individually. One such ground is an investment of at least BGN 600,000 in a property purchase, subject to meeting the established requirements (payment must be confirmed through a licensed Bulgarian credit institution).

You should also take into account several additional costs:

• notary and registration fees;
• local property acquisition tax;
• annual property tax in the future;
• the residential complex's maintenance fee (if applicable).

To understand all the features of each property and organise the transaction properly, working with specialists in the relevant field is particularly important for foreign nationals. 

Example Calculation for Buying an Apartment on an Instalment Plan 

To understand how this arrangement works, you can take a property priced at EUR 100,000 as an example.

However, this example does not include the additional costs the buyer must pay. Notary, registration, tax and other related costs must therefore be added to the stated property price. Before completing the transaction, it is therefore advisable to obtain an individual calculation for the specific property, taking all the details into account.

FAQ

1. Can you buy an apartment in Bulgaria with USDT?

Yes, this is possible, provided that the seller/developer agrees to this payment method. Both parties must also properly document all the terms of the future transaction: the property's price should be fixed in euros, and the agreement must clearly set out the complete procedure for converting cryptocurrency.

2. Can you use Bitcoin for the initial payment?

Yes, if the seller/developer agrees to this option. The agreement should specify the initial payment amount in euros, the cryptocurrency to be used for payment, the specific exchange rate and the point in time when it is fixed.

3. Is taking out a mortgage mandatory?

No, this option is not mandatory. Today, most developers offer instalment plans under which the buyer pays the full property price according to a set schedule. There is no need to take out a mortgage beforehand.

4. Is it safe to pay for property with cryptocurrency?

Security depends not on the specific cryptocurrency but on the legal aspects of completing the transaction. The buyer should therefore check the seller/developer and the selected property in advance, confirm the source of their own funds and draw up a payment schedule. It is best to involve experienced specialists who will support their client at every stage of the transaction.

5. Does buying an apartment entitle you to a residence permit?

No, buying any property in Bulgaria does not automatically entitle the buyer to a residence permit. To obtain such a permit, you need to meet one of the stated grounds/requirements set out in the country's legislation.
