Also, are there other liens which can cloud title such as judgements, IRS, child support, installment loans, etc.

Of course some liabilities are transferred such as judgement liens or HoA fees or water / sewage fees.

I'm dealing with a owner and a judgement lien this is my first one like this how do I go about finding the creditor and how do I go about removing the lien off the home to resell to an investor

The roof also took much longer than anticipated, in part due to a lot of rain, and also in part giving the job to the wrong contractor who also kind of took his time with it. 

At first glace it seems like most have an appraised value below the judgement to be raised.

It wasn't her fault she was leading me from her best judgement and if I wanted to do what she had done it would have been great advice, but I wanted to househack for as cheaply as possible in a good location and she didn't get that. 

If she doesn't leave, begin eviction for a holdover where, in many jurisdictions is much easier to win a judgement than for non-payment or other lease violations (where they can just show up to court with the cash and they get to stay, despite your time and court costs).Also, it would be very helpful to us for you to put your RE market in your profile or at least in your post, because in this part of real estate, too, location matters. 

For example, my rentals are in Florida and when it rains, the grass grows like crazy.  

Hello All-I closed on a property  in April and after the recent rain in DC I discovered the floor buckling as well as warped drywall and other damage.

You need to exercise good judgement and not be afraid in making your choices.
