Si la propriétaire accepte mon garant, je signerai le bail demain.

Because in French, after si meaning if, you normally do not use the future tense.

For a real or likely future situation, French uses:

• si + present
• future in the main clause

So:

• Si la propriétaire accepte mon garant, je signerai le bail demain.

This is the standard pattern for If the landlady accepts my guarantor, I’ll sign the lease tomorrow.

A useful rule to remember:

• si + présent → futur
• si + imparfait → conditionnel

For example:

• Si j’ai le temps, je viendrai.
• Si j’avais le temps, je viendrais.

So si la propriétaire acceptera would be incorrect here.

Je signerai is the future simple, meaning I will sign.

That fits the sentence because the signing will happen later, after the condition is met.

• je signe = I sign / I am signing
• je signerai = I will sign

So the sentence structure is:

• condition now or in the future: Si la propriétaire accepte...
• result in the future: je signerai...

You could also hear je vais signer in everyday speech, which also means I’m going to sign, but je signerai is perfectly natural and slightly more neutral or formal.

Propriétaire means owner. In this context, it means the owner of the property, often translated as landlady if the owner is a woman.

Here it is la propriétaire because the owner is female.

A useful detail: propriétaire often keeps the same spelling for masculine and feminine.

• le propriétaire = the male owner / landlord
• la propriétaire = the female owner / landlady

So the article tells you the gender here.

In housing and rental French, un garant is a guarantor: a person who promises to cover the rent if the tenant cannot pay.

This is very common in France when renting an apartment.

So mon garant means my guarantor.

It does not mean just a general supporter or reference. In this context, it has a specific financial/legal meaning.

Because garant is masculine here.

• mon garant = my guarantor

If the guarantor were specifically female, you may also see ma garante. But in real rental language, garant is very commonly used, sometimes even in a fairly generic way depending on context.

So for a learner, the safest understanding is:

• mon garant = my guarantor

Because accepter takes a direct object in French.

You accept someone or something directly:

• accepter une offre
• accepter une demande
• accepter un candidat
• accepter mon garant

So mon garant is the direct object of accepte.

French does not use a preposition here.

Le bail means the lease.

It is a specific legal word for a rental agreement. In English, lease is the best translation here.

A contrat is a contract in a broader sense. A bail is a particular kind of contract related to renting.

So:

• signer le bail = to sign the lease

That is the natural expression in French for renting a property.

Using le bail suggests the speaker means a specific lease that both people already understand: the lease for this apartment.

French often uses the definite article where English might also use the:

• je signerai le bail demain = I’ll sign the lease tomorrow

If you said un bail, it would sound less specific, more like a lease in general.

Here the situation is clearly about one particular rental agreement, so le bail is the natural choice.

Yes. Demain is fairly flexible.

The original sentence:

• Si la propriétaire accepte mon garant, je signerai le bail demain.

You could also say:

• Demain, si la propriétaire accepte mon garant, je signerai le bail.
• Si la propriétaire accepte mon garant, demain je signerai le bail.

But the original version sounds very natural. Putting demain at the end is a common, simple way to add the time.

This is a very common learner question because the spellings are close.

• je signerai = future simple = I will sign
• je signerais = conditional = I would sign

In pronunciation, these are often distinguished as:

• signerai → roughly seen-yeuh-RAY
• signerais → roughly seen-yeuh-REH

In many accents, the difference can be subtle, but in careful standard pronunciation there is usually a distinction between the future ending -ai and the conditional ending -ais.

In this sentence, je signerai is correct because it means I will sign, not I would sign.

It is mostly neutral and perfectly natural.

The vocabulary is a bit practical and real-life:

• propriétaire
• garant
• bail

These are common words in rental situations, and je signerai sounds slightly more polished than very casual spoken French, but still completely normal.

In very casual speech, someone might also say:

• Si la propriétaire accepte mon garant, je vais signer le bail demain.

That is a bit more conversational, but the original sentence is totally natural and correct.

Yes, French speakers could absolutely say this.

It sounds like something a person might say when talking about renting an apartment. The wording is clear and realistic, especially in France, where garant is a very common part of rental discussions.

The sentence is slightly tidy and complete, which can make it feel a little more textbook-like, but it is still natural French, not artificial French.
