Does Paying Back Nearly Double Mean Your Mortgage Rate Is 100%?
INGAR · · Financing
No. The fact that your payments add up to almost twice what you borrowed does not mean the loan carries a 100% annual interest rate.
The confusion comes from blending three numbers that measure completely different things:
- The loan's effective annual rate (TEA in Spanish).
- The total interest accrued over 20 or 25 years.
- The all-in cost, which also covers insurance, mandatory funds, fees and mortgage-related expenses.
And there's a fourth element unique to Uruguay: most home loans here are denominated in Unidades Indexadas (UI, an inflation-indexed accounting unit). Your payment can be fixed in UI while the peso amount changes every single month.
A concrete example is the fastest way to pull these apart.
Three concepts that are not the same thing
| Concept | What it measures |
|---|---|
| TEA | The rate charged each year on the outstanding balance, in the loan's currency or unit of account |
| Accrued interest | The sum of every interest payment made over the life of the loan |
| Loan-to-value | How much of the home's value the bank is willing to lend |
| All-in cost | Principal, interest, insurance, mandatory funds, fees and every other expense |
So a product that finances 100% of a home does not charge a 100% interest rate. Those percentages describe entirely different realities, and the fact that the figures look alike is pure coincidence.
Two BHU products worth comparing at high loan-to-value
BHU (Uruguay's state-owned mortgage bank) offers several mortgage lines. These two are the ones that let you compare high loan-to-value financing, with conditions as published on August 1, 2026:
| Product | Published TEA | Maximum financing | Maximum term | Principal |
|---|---|---|---|---|
| Podés Comprar | from 3.75% | up to 95% with the Fondo de Garantía | 25 years | 100,000 to 2,800,000 UI |
| Préstamo Soñado | from 4.50% | up to 100% | 25 years | 100,000 to 2,800,000 UI |
Sources: BHU — Podés Comprar and BHU — Préstamo Soñado.
In both cases these are "starting from" rates. The bank itself notes that the TEA shifts depending on the term, the share of the property's value being financed, the applicants' income profile, and whether a saver's discount applies. The published rate is a starting point, not a personal quote.
The example: 100,000 UI at a 4.50% TEA
Take a loan of 100,000 UI at a 4.50% TEA, amortized on the French system — equal installments in UI.
The table below shows only the financing component: principal and interest. It does not yet include the Fondo de Protección al Inmueble, life insurance or any other charge.
| Term | Financing payment | Principal + interest | Accrued interest |
|---|---|---|---|
| 10 years | 1,032.0 UI | 123,845 UI | 23,845 UI |
| 15 years | 760.4 UI | 136,870 UI | 36,870 UI |
| 20 years | 627.8 UI | 150,669 UI | 50,669 UI |
| 25 years | 550.7 UI | 165,217 UI | 65,217 UI |
Over 25 years, the financing interest works out to roughly 65% of the original principal.
That 65% is not the rate. The rate is still 4.50% effective annual in UI, applied over 300 months to a balance that shrinks with every payment. What multiplies the number isn't the rate — it's time.
It's worth not overstating the counterargument either. The fact that this example doesn't reach 100% in interest doesn't mean it can't happen: a hypothetical 30-year loan at a 5.50% TEA already accrues more than 100% of the principal in interest. The point isn't that "you never get there" — it's that accrued interest and the interest rate are two different quantities.
That table isn't everything you pay
BHU's product specifications state that the monthly payment also includes the Fondo de Protección al Inmueble (FPI, a mandatory property-protection fund): a monthly contribution equal to one twelfth of 0.35% of the original principal.
On a 100,000 UI loan:
- Monthly FPI: roughly 29.2 UI.
- FPI accrued over 25 years: 8,750 UI.
- Payment before life insurance: about 579.9 UI.
- Principal + interest + FPI: about 173,967 UI.
On top of that comes mandatory life insurance, priced according to the loan amount, the term and the applicant's circumstances. If it's rolled into the loan, it changes the principal and therefore the monthly payment too.
That's why the 165,217 UI in the earlier table is not the loan's final cost: it's principal and interest in a math exercise, nothing more.

Why the term changes the outcome so dramatically
Comparing the same loan over 20 versus 25 years:
- The financing payment drops by about 77.1 UI per month.
- Total principal and interest rises by roughly 14,548 UI.
- The FPI adds another 1,750 UI across those five extra years.
- Life insurance can also get more expensive with the longer term.
Stretching the term is a perfectly legitimate way to get the payment to fit your budget, but it has a price tag, and you want to see it before you sign. The real decision is finding a payment you can sustain without dragging the debt out longer than you need to.
Fixed in UI is not fixed in pesos
The UI is adjusted daily, tracking the previous month's change in the IPC (Uruguay's consumer price index), under article 2 of Ley 17.761.
As of August 1, 2026, one UI was worth $6.6300 in Uruguayan pesos, according to the Instituto Nacional de Estadística (INE, the national statistics agency).
At that value:
- A financing payment of 550.7 UI came to about $3,651.
- Adding the FPI from our example, about $3,845, before life insurance.
The number of UI stays fixed; the number of pesos does not. That's why there's no way to know at the outset how many nominal pesos you'll hand over across 25 years, and it's also why "1.65 times the principal" is a figure expressed in UI: in nominal pesos, after 25 years of inflation, the total paid out can comfortably exceed double the pesos originally lent. That still isn't a 100% interest rate. It's inflation.
The UI protects the real value of the loan: the debt doesn't get eroded away by rising prices. For the borrower, that cuts both ways: if your income grows more slowly than the IPC, the payment eats a bigger share of your paycheck even though the UI amount hasn't moved. A payment that's stable in real terms doesn't guarantee a stable payment-to-income ratio.
What 100% financing actually demands
Préstamo Soñado will finance up to 100% of the home's value, but it requires mortgages on:
- The property you're buying.
- A second property, which does not have to belong to the applicants.
That second property is no minor formality. Under the current specifications:
- It must be approved by BHU.
- Its appraised value must be at least 40% of the appraised value of the home being purchased.
- It is not released automatically after a few years — the client has to request the release.
- The loan must have had no late payments in the previous 12 months.
- At least 30% of the principal must have been repaid; if income is documented through self-employment, at least 50%.
Whoever puts up that second property — often a family member — is taking on a commitment measured in years. Talk it through with the bank and with your escribano (the notary who handles property transfers in Uruguay) before it becomes a promise made over dinner.
100% financing doesn't mean you can skip saving
The 100% refers to the home's value, not to the transaction as a whole. Beyond the purchase price, you'll pay:
- ITP (the property transfer tax).
- Notary fees and closing costs for the sale and for both mortgages.
- Broker's commission, where applicable.
- Bank processing fees. The current Préstamo Soñado specifications set an application filing fee of 4,850 UI.
- Life insurance and any other required policies.
- Any gaps that emerge from the appraisal or the credit review.
Taken together, the costs of a financed purchase usually land somewhere between 10% and 13% of the price. We break that down with real figures in what it costs to buy a property and in the hidden costs of buying with a mortgage.
Before you put down a deposit on a property, two steps will save you grief: get a mortgage pre-approval and confirm that both properties are acceptable as collateral.
The Fondo de Garantía and the 95% option
Podés Comprar reaches 95% through the Fondo de Garantía, a mortgage guarantee fund administered by the Agencia Nacional de Vivienda (Uruguay's national housing agency). It was created by article 7 of Ley 18.795; its name and wording were later amended by subsequent legislation, though BHU still markets it under the acronym FGCH.
It isn't granted automatically. Its current requirements include:
- Qualifying as a borrower at a participating bank.
- Using the loan for a single primary residence.
- Household net income of no more than 100 UR (Unidades Reajustables, a wage-indexed unit of account).
- Being free of liens, court-ordered restrictions and encumbrances.
- Having accumulated savings of between 5% and 25%.
- Meeting the value caps and other requirements that apply to the property.

Does holding a rental deposit account at BHU help?
It can help, but simply having one isn't enough.
Rental guarantee accounts at BHU can unlock:
- An extra 10% in financing on top of whatever profile the bank assigns you.
- A preferential saver's TEA.
The conditions are specific: the account must be at least 12 months old, and the average balance over the previous six months must equal at least 5% of the loan requested.
Here's the fine print: a rental guarantee balance counts, but it rarely gets you there on its own. On a 100,000 UI loan you'd need an average balance of 5,000 UI — roughly $33,000 at August 2026 values. On a 1,000,000 UI loan, 50,000 UI. It's a useful starting point, not a complete strategy.

How to compare two mortgages without getting it wrong
Picking whichever one has the lowest opening payment is the quickest route to a bad decision. Ask every lender for a written simulation that spells out:
- The principal actually disbursed and the net amount the seller receives.
- The loan's currency or unit of account, and how it's indexed.
- The TEA that applies to your profile, not the "starting from" rate.
- The term and the amortization system.
- The payment in the loan's currency, broken out to show which portion is financing.
- Total principal and interest.
- Life insurance, property insurance or an equivalent fund (the FPI).
- Commissions, fees and the cost of registering the mortgages.
- The terms and cost of paying the loan off early.
- The loan-to-value ratio and the appraised value used.
- Any additional collateral required.
And one rule that sounds obvious yet almost never gets followed: compare offers at the same amount, in the same currency, over the same term. A lower payment achieved by stretching the loan five more years isn't a cheaper offer — it's a different transaction.
The short version
- Repaying 1.65 times the principal in financing payments does not equal a 100% TEA.
- That 1.65 figure is expressed in UI, so it tells you nothing about the future total in pesos.
- Your actual BHU payment also includes the FPI and mandatory life insurance.
- Financing 100% requires a second property as collateral under demanding conditions, and it doesn't cover the costs of the purchase.
- The published rate is a "starting from" number: the final offer depends on your profile and on the deal itself.
- To compare mortgages, look at the all-in cost — not the rate, and not the first payment.
At INGAR we can help you work out the full cost of a purchase, see how the mortgage shapes your property search, and coordinate the transaction with the bank and the escribano. Approval and final terms are always the lender's call.
Frequently asked questions
Does repaying almost double the loan mean the rate is 100%?
No. Payments adding up to nearly twice the principal is not the same as a 100% annual rate. Three separate things are in play: the effective annual rate, the interest accrued over 20 or 25 years, and the all-in cost, which also includes insurance, mandatory funds, fees and mortgage-related expenses.
Is the payment on a Unidades Indexadas loan fixed?
It's fixed in UI, not in pesos. The UI adjusts daily, tracking the previous month's change in the IPC under article 2 of Ley 17.761, so the peso amount changes every month.
What is the Fondo de Protección al Inmueble, and why does it raise my payment?
It's a monthly contribution BHU builds into the payment, equal to one twelfth of 0.35% of the original principal. That's why a principal-and-interest table doesn't reflect everything you pay each month.
Does 100% financing mean I don't need savings?
No. The 100% refers to the home's value, not to the whole transaction. Beyond the price you still owe the ITP, notary fees and closing costs for the sale and the mortgages, and the broker's commission where one is involved.
What does Préstamo Soñado require to reach 100%?
Mortgages on both the property you're buying and a second, additional property, which doesn't have to belong to the applicants.
How does BHU get to 95% financing?
Through the Fondo de Garantía administered by the Agencia Nacional de Vivienda, created by article 7 of Ley 18.795.
How do I compare two mortgages without getting it wrong?
Picking whichever one has the lowest opening payment is the quickest route to a bad decision. Ask each lender for a written simulation showing the principal actually disbursed and the net amount you receive, along with every component of the monthly payment.
To size up your own situation before requesting a simulation, our mortgage calculator estimates the payment and the total under whatever terms you choose, and our property listings show what today's prices look like in the segment you're considering.
