builder is trying to build a garage that too close to my property

[Jin Moon]

Hello guys,

I need your advice on my situation.

We are a process of building a house with a builder and we are about to install cabinets. and  This is not a normal construction process it is like the builder gets a loan and finishes and sell it to buyers.

the issue is that the builder just sold right side of the lot and they are trying to extend driveway and to add a garage.
if the builder extends driveway and adds a garage then the neighbor's car will come and out only 15~20' from my dining room and my children's room

when I picked my lot out the builder side realtor told me that we will have about 50' between our property and neighbors.
because I had the same concern that what if they extend or add a garage then I would not have enough space between me and the neighbor.

I told the builder about my concern and  he said there is nothing wrong with doing that if I don't want that lot they can't give my deposit money back(they don't call it as earnest money)

I also contacted the realtor and he is avoiding a clear answer.

What should I do with this situation?
