Short answer. Yes. Article 1198 says the debtor loses every right to make use of the period when by his own acts he has impaired the guaranties or securities after their establishment. By letting the mortgaged property fall into ruin, your borrower forfeited the benefit of the deadline, so you may demand payment now even before the due date.

Why a deadline can be cut short
Normally a debtor is entitled to the full period agreed, and you cannot demand early payment just because you would like your money back sooner. Article 1198 is the exception. It lists five situations in which The debtor shall lose every right to make use of the period, meaning the debt becomes immediately demandable even though the maturity date has not arrived. The common thread is that the debtor has done something that unfairly undercuts the creditor's position. When one of these grounds is present, the benefit of the term, which the law presumes exists for the debtor, is stripped away, and the creditor may call in the loan at once.
Impairing the security is one of those grounds
Your situation fits the third ground squarely. The debtor loses the period When by his own acts he has impaired said guaranties or securities after their establishment. A mortgage is exactly such a security: the property stands as the creditor's protection in case the loan is not paid. When the borrower lets that property fall into ruin through his own conduct, whether neglect, damage, or waste, he weakens the very thing that made the creditor comfortable waiting until the due date. The law responds by taking away his benefit of time. The bargain was that the creditor would wait while properly secured; the borrower cannot both keep the wait and destroy the security.
The borrower's one way to keep the period
The same ground contains a safety valve, but notice who it is aimed at. Where the securities disappear through a fortuitous event, by accident and not the debtor's fault, the debtor keeps the period only if he immediately gives new ones equally satisfactory. That reflects a difference the article draws: a debtor who loses the security by his own acts is treated more harshly than one struck by chance. In your case the impairment came from the borrower's own conduct, not a pure accident. Still, if he moves quickly to restore or replace the security with something equally satisfactory, that may address your concern; absent that, the loss of the period stands.
What you must show, and what it means
Two points before you act. First, there has to be genuine impairment. Ordinary wear, or a drop in market value not caused by the borrower, may not be enough; the article targets the debtor's own acts that meaningfully weaken your security. Be ready to show what he did and how it reduced the protection you bargained for. Second, the effect of the article is that the obligation becomes due now, making the debt demandable ahead of time and opening the door to collection and to enforcing the mortgage. The other grounds in the same article, insolvency, failing to give promised security, breaking an undertaking, or attempting to abscond, work the same way if any of them also applies.
