How to choose a reliable developer in Bulgaria
Purchasing a property during the construction phase can provide a better price and increase the cost by the time the building is put into operation.

Purchasing a property during the construction phase can yield a better price and increase the value by the time the building is ready for occupancy. However, it is at this stage that the quality of the developer’s due diligence is most crucial. Below is a step-by-step due diligence methodology, a list of documents, financial and legal reliability indicators, and key contract terms that will protect your money and timelines.
Understanding the project life cycle: what and when to check
- Before the start of sales: land title, urban planning parameters (UPP), building permit (Permit for construction), design documentation.
- Construction: acts of readiness – Act 14 (load-bearing structure), Act 15 (acceptance from the contractor to the investor), Act 16 (permit for use/commissioning).
- After entry: final notarial deed, management of common areas, warranty periods.
Documents and checks: legal checklist
Ask the developer and/or check with a consultant:
- Right to a land plot: notarial deed to the land, absence of arrests and encumbrances (certificate from the Imoten register).
- Urban development documentation: PUP/skitz, compliance with development parameters (KINT, height, footprint).
- Construction permit (Permit for construction): validity, compliance with the project.
- Construction acts: work schedule and target dates for Acts 14/15/16.
- Contracts with contractors and author’s supervision: who builds, experience, responsibility.
- No debts: taxes, utilities, land payments.
- The developer’s previous projects: addresses, actual delivery dates, any complaints about quality.
- Liability Insurance: Builder’s/Contractor’s Policy (if applicable).
Reputation and transparency: practical markers of reliability
- Official website and regular photo and video reports from the site.
- Public calendar plan with stages and dates.
- A flexible and clear payment scheme linked to completion certificates.
- Availability of bank financing for the project or bank accreditation (often means additional audit).
- A list of completed projects with actual addresses and contact information for management companies.
- Transparent terms of the maintenance fee and a clear management company.
- Readiness for independent technical expertise and “snagging” before transfer.
Financial indicators and payment structure
The optimal scheme reduces the risk for the buyer:
- Reservation: a small non-refundable/partially refundable amount with clear conditions.
- Payment schedule by milestones:
- 10–20% upon signing the Preliminary Agreement;
- up to Act 14 – limited percentage;
- up to Act 15 – next part;
- final payment – after Act 16 (input).
- Escrow account or bank guarantee (if available) – protection until the agreed stage is reached.
- Avoid “aggressive” demands for large advance payments without adequate guarantees.
Contractual basis: what to pay attention to in the Preliminary Agreement
Required sections and wording:
- Subject: precise description of the property (sq. m, floor, landmarks, parking spaces, warehouse, etc.), shares in common areas.
- Price and currency clause: fixed/indexed, revision conditions.
- Deadlines and responsibilities: deadlines for Act 14/15/16, penalties for late payment.
- Quality and specifications: detailing of finishes, engineering, material brands (Specification/Technical Sheet).
- Warranties: minimum 5 years for the structure; 2 years for engineering systems and finishing (practice may vary, so please document this in writing).
- Handover and snag list: defect identification procedure and deadlines for elimination.
- Design Deviations/Changes: List of Acceptable Variations and Compensations.
- Termination: grounds, refund procedure, penalties.
- Notarial acts: the procedure for signing the final notarial deed.
- Management and maintenance: size, indexation, range of services, rental rules.
Construction quality: technical control
Before paying the final tranche, request or arrange:
- Independent technical supervision: inspection of monolithic/frame elements, waterproofing and thermal insulation, window systems, facades.
- Engineering networks: water pressure, electrical (panel, cable cross-sections, circuit breakers), ventilation, sewerage.
- Common areas: elevators, fire safety, entrances, parking, landscaping.
- Area measurements: comparison with the plan (net/gross, common area coefficients).
- Sound and heat insulation: especially for resort areas and ground floors.
Management company and operating costs
Estimate the total cost of ownership in advance:
- Maintenance fee (annually): includes cleaning, security, landscaping, swimming pools, lighting, administration.
- Utilities: water, electricity, internet, TV.
- Rental rules: can you rent it out yourself, penalties, management fees.
- Reserve fund: creation/replenishment, procedure for approving co-owners’ budgets.
Red flags: signs that risks are increased
- Key documents are missing or not presented; there are no “live” construction photos.
- “Special price only today”, intrusive prepayments without guarantees.
- Unclear sources of funding for the project.
- Systematic delays in past projects without convincing reasons.
- Hidden payments and slippery wording in the contract.
- Reluctance to record material specifications and warranties in writing.
Questions for the developer: mini-brief for the meeting
- What are the specific dates for Act 14/15/16 and what has already been accomplished?
- Who is the general contractor, who is responsible for the author’s and technical supervision?
- Is there bank financing/escrow?
- What does the final price consist of: what is included, what is extra?
- The size and composition of the tax support, rental and management rules.
- What are the warranty periods for different sections of work and how are defects reported?
- Is it possible to conduct independent technical supervision and “snagging” before the final payment?
- Examples of completed objects: addresses, contacts of managers.
Payment Scenarios: Examples of a Secure Structure
- Scenario A (conservative): 10% – contract; 20% – Act 14; 30% – Act 15; 40% – after Act 16.
- Scenario B (with a bank): down payment; principal – loan/mortgage after Act 16; interest – only after entry.
- Scenario C (Individual): More payments, but smaller shares – each step tied to a measurable milestone and verification.
Risk and budget optimization
- Specify as many parameters as possible (materials, brands, deadlines) in the appendices to the contract.
- Compare the total cost of ownership from different developers: fees, utilities, insurance, repairs.
- Structure payments so that the last tranche is after Act 16 or under a bank guarantee.
- Use professional support: a lawyer, a technical inspector, a VAT accountant (if you plan to rent with VAT).
