The hidden cost of waiting: what one more year of hesitation really costs
April 9, 2026"I'll wait a bit — the market will probably drop." Everyone thinking about buying an apartment in Sofia has either said or heard this phrase. It sounds reasonable. Why rush when prices are at all-time highs?
The problem is that this logic ignores three forces working against you every month you postpone. And their cost is not symbolic — it's concrete, measurable, and often larger than the drop you're hoping to catch.
The three forces working against you
1. Prices keep climbing
Bulgaria's House Price Index (HPI) according to Eurostat shows sustained growth:
| Year | Average annual growth (HPI) |
|---|---|
| 2020 | 4.6% |
| 2021 | 8.7% |
| 2022 | 13.8% |
| 2023 | 9.9% |
| 2024 | 16.5% |
| 2025 | 14.7% |
The average growth for 2020–2024 is ~10.7% per year. Even with a more conservative projection of 10% per year, an apartment costing 200,000 EUR today would be 220,000 EUR in 12 months.
2. The savings gap widens
If you save 500 EUR per month, in one year you'll have 6,000 EUR more. But the down payment (20%) on a 220,000 EUR apartment is 44,000 EUR — 4,000 EUR more than today's 40,000 EUR. Your savings grow linearly, but prices grow exponentially. Every year the gap widens.
3. Interest rates can shift
Bulgaria has some of the lowest mortgage rates in the EU — averaging 2.47% as of October 2025 (BNB data). But these levels are not guaranteed. With eurozone membership and global monetary shifts, even a modest increase to 3.0–3.5% significantly raises the monthly payment and total interest over 25 years.
Scenario: waiting 1 / 3 years
Let's do the math. Starting point: a 65 m² apartment in Sofia at a median price of 2,100 EUR/m² (early 2026) — but for round numbers we'll use 200,000 EUR. Down payment: 20%. Term: 25 years.
While you wait, you pay rent of 550 EUR/month and save an extra 500 EUR/month.
| Buy today | Wait 1 year | Wait 3 years | |
|---|---|---|---|
| Property price | 200,000 EUR | 220,000 EUR | 266,200 EUR |
| Down payment (20%) | 40,000 | 44,000 | 53,240 |
| Extra savings | — | 6,000 | 18,000 |
| Loan amount | 160,000 | 170,000 | 194,960 |
| Interest rate | 2.47% | 2.70%* | 3.40%* |
| Monthly payment | 715 EUR | 780 EUR | 966 EUR |
| Total interest (25 yr) | 54,612 | 63,965 | 94,717 |
| Rent paid while waiting | — | 6,600 | 19,800 |
| Hidden cost of waiting | — | ~16,000 EUR | ~60,000 EUR |
The "hidden cost" is the sum of extra interest paid + rent, compared to buying today. At 3 years of waiting it reaches ~60,000 EUR (117,350 BGN) — almost one-third of the original property price.
Hidden cost of waiting (extra interest + rent)
And the monthly payment? It jumps from 715 EUR today to 966 EUR — 251 EUR more every month for 25 years.
When waiting actually wins
Let's be honest — there are situations where waiting is the right call:
-
Your income is growing faster than prices. If you expect a significant raise (new position, second income stream), waiting can improve your loan-to-income ratio. Average wage growth in Bulgaria is 10–13% per year (NSI, 2022–2025), but that's the average — your individual growth may be higher or lower.
-
Rates drop significantly. If rates fall from 2.47% to 1.5–2.0%, the more expensive property could come with a similar payment. But current levels are already historically low for Bulgaria.
-
The market actually crashes. The last significant decline in Sofia was 2008–2010: prices dropped by ~37%, but recovery to pre-crisis levels took 10 years. If you had bought at the 2008 peak and held until 2018, you would have just broken even. If you had bought in 2010–2012, you would have gained significantly.
-
You don't have enough for a down payment. If your down payment is under 10%, waiting to save more may be more rational than taking a more expensive loan with PMI (private mortgage insurance).
The key point: waiting only wins if your assumptions about the future turn out to be correct. And the statistics of the last 5 years show that Sofia's market surprises to the upside more often than to the downside.
How to check your own case
The numbers above are a typical scenario. Your situation may be different — different price, different income, different down payment percentage.
Planelka's calculator lets you enter your specific numbers and see the full picture: monthly payment, total interest, stress test, and what percentage of your income goes to housing. Not the bank calculator that only shows the payment — but everything: taxes, notary, insurance, renovation, reserve.
Enter the numbers for the "buy today" scenario and for the "buy in 1–2 years" scenario — the difference will tell you more than any forecast.
