If the smoke smell is bad, you should probably wash everything down first, clean the carpets, and then use the ozone generator.These work great on odors from pets, food, or smoke, but it sometimes still requires heavy cleaning first.

They will look at your expenses- college tuition , insurance, food, car, gas, etc to see if you qualify for a mortgage.Also- one option is to get added to your paretns credit card if they have had it s along time with good credit- this will boost your score. 

There was food on plates left around the living room, fly strips hanging from the kitchen light, fruit snacks on the carpet, and the toilets/showers looked like they had not been cleaned in 6+ months.

Food for thought ....P.

How do you handle disputes over common area use, stealing food from each other, taking out trash, someone that monopolizes the space, etc.?

I am 22 and fresh out of college working a sales position for a food company.

I thought this issue was resolved it is not resolved now I had to have a wall rebuilt that was ate up with mold luckily I have caught the water early this time and cut the drywall back so the only mold food is the bottom wood beam. 

I would go one step further and point out that the food they eat leads to most of their medical problems.
