Please consider the following two similar sentences:
If we move here, we will buy a house.
If we moved here, we would buy a house.
The question is this: what is the difference between them?

 

Here is the explanation about my answer:

The difference between the two sentences lies in the tense used and reflects the certainty of buying a house.

If we move here, we will buy a house. (Present tense)

This sentence talks about a future decision based on a present condition. It expresses a strong likelihood or certainty that buying a house will happen if the move takes place.

If we moved here, we would buy a house. (Past conditional tense)

This sentence refers to a hypothetical scenario in the past. It suggests that buying a house was a strong possibility had you moved there, but the move itself didn't happen.
