Buying 1st home and settlement obstacles

I’m new to the group and although my debt is relatively minimum,I just graduated from college and am in the process of buying my first house and so therefore want to get a hold on the debt now. My question is this-financially I wasn’t prepared to purchase this house but I have a 9-month-old and the opportunity that the seller presented was something I couldn’t pass up (i.e. An older relative is selling me their house for $30,000 less than the appraisal value).

Having just left college,I have some credit cards and other accounts in collections that are on my credit report and fear that some more may pop up eventually.What could happen,at worst case scenario,to prevent me going to settlement on this house and what can I do to get prepared or fix this before it happens.Any advice is greatly appreciated.I don’t have any extra cash on hand to pay off any of the accounts in collections so what other options do I have?
