She has lived with us for 4 years out of 5 years of marriage.
She is a healthly, working 56 year old woman whose only daughter is my wife.
She refuses to have no life except for to wait for us to take her out to the mall, dinner, etc.
She has very few friends and no interest in finding a man.
Her bedroom is down the hall from us.
We support her completely and do not ask her for rent.
We need our privacy and are becoming desparate.
We are thinking of converting the garage into this apartment with a separate entrance.
If we convert the garage, we will make it feel like a part of the house with every convenience and great materials. We will use a reputable construction company for the remodel, but are not sure if this is enough space.
