So, I don't think she makes 31K per year because if her net monthly income is 2600 then (2600 * 12) = 31,200.......so unless she pays no taxes, then I'm assuming she makes around 50K. Also not sure if buying a house on such a tight budget is wise. If anything happens with the house it could totally wipe her out. Also her down payment comes out to be just 5% of the value of the house. I am not certain this was a mustachian move. I could be wrong in my analysis, I have been told I can be an a$$ sometimes. ( I noticed in her monthly budget, nothing is going to investments so this house is her only investment which makes this even more dangerous)
