can i take legal action against my mobile home park?

My boyfriend and I just bought an as is mobile home. We liked it but when we looked at it the water wasn't on. We asked the lady before we bought it why the water wasn't on and she said it will be turned on after we buy it and do the final walk through because it might leak so no big deal. We waited 1 week for her to have time to do a walk through. Still no water. When they did the walk through they said the water leaks outside so we have to get it repaired. Half ther responsibility half ours. 3 weeks later no water, no estimate for our "share", and we have no money to get it fixed on our own. We don't have any money for an attorney and they know it. We are trying to figure out how we are going to pay our rent on the first. The reason for the financial problem is cps got involved with me at my previous address because my 11 year old son fell asleep in class and they think he has a 2am bedtime everynight so to avoid him going into foster care my boyfriend quit his job. For some reason I need a 24 hour babysitter for my 11 year old son even when he's sleeping.
