Short answer. Only if the will says so. Article 793 provides that property acquired after a will is made passes under it only where the will expressly shows that intention. Silence is not enough, so a condominium bought later usually falls outside the will and is distributed as though there were none.
What the law says
Property acquired after the making of a will shall only pass thereby, as if the testator had possessed it at the time of making the will, should it expressly appear by the will that such was his intention.

The default runs the other way from what most people assume
A will is commonly imagined as a standing instruction that sweeps up whatever the testator happens to own when he dies. Article 793 reverses that for property acquired later: it passes under the will only should it expressly appear by the will that such was his intention. The word doing the work is expressly. A general reference to the testator's property, or a clause about the residue, is thin ground; what the article contemplates is language directed at the point, saying that the will is to cover property acquired after its execution.
What happens to the condominium instead
Property that the will does not carry is not lost and does not go to the government. It passes as an intestate estate — that is, to the heirs the law designates, in the shares the law fixes, exactly as if your father had left no will at all as to that unit. So an estate can be settled partly under the will and partly under the intestate rules, which is common and perfectly workable, though it frequently produces a distribution of the condominium that differs from the pattern of the will and that the family did not expect.
The article is about property, not about value
Two situations are often confused with this one. If the will left a named beneficiary a sum of money or a share of the estate rather than a specific thing, later purchases simply change what the estate is worth and the share is computed on the whole of it. And where the testator sold the thing he had bequeathed and bought a replacement, the question is what happened to the original gift, not whether the will reaches forward. Article 793 bites on a specific asset acquired after execution and not otherwise mentioned.
Read the will before anything else
The answer is in the document, so it should be examined clause by clause with the acquisition date of the condominium beside it — the deed of sale or the transfer certificate will fix that date. Look for any provision addressed to future or after-acquired property, and note whether a later will or codicil was executed after the purchase, which would resolve the matter outright. Where a testator is still living, this is among the simplest problems in succession to fix: a codicil that names the property removes the argument entirely.
