<prompt> Human: Ok so heres a little back story:I am 25 26 in August Husband is 26. We have one baby born Oct2014 and another due October2015 it happens dont ask...I have a decent job I make 55K a year and my husband makes 40K a year. Current debt:20K on my car20K on husbands car3,762 for a foundation repair should be paid off in AugustMortgage we owe 145K and the house is estimated valued at 156K we have owned it for almost 2 years my hesitation for movingMonthly income is 6,288 Monthly Expense includes everything except gas, groceries and extra payments on the Credit card total: 3,256We have a 4 bedroom3 bath home. which my mom lives in the basement its basically one large room with a bathroom to the side. She cannot afford rent and pays bills when she can i.e the 50 water bill or some other item that really doesnt make or break anything. When purchasing the house we always had the idea of having an entertainment room in the basement, and our two age gapped kids in the distant future have a room each but as you can tell life happens. now the house feels quite cramped and with another baby on the way I am contemplating moving or having an addition installed. With baby 2 in the picture our expenses will go up to about 3,800 for the extra day care expense.So PFers what is your experience with adding an addition on to a house i.e. round about cost, time, hassles, etc. I live about 45 minutes outside of Atlanta without traffic While I know its not adviesable to not put a downpayment on a house we both have a VA loan option and we are currently using my VA loan on our current home and we could use his for a new home requiring no down payment with good credit which we have. Thanks in advance for any suggestions you guys have!  <response>: i would not recommend making additions on the income you have. additions are a ton of work and cost overrunstime are extremely likely. there are so many hurdles and red tape you need to go through, it is a very big hassle. and most of the times, they do not make their money back in ROI when selling the house.
