Yes it's definitely a HUD report. I'd be more worried about their Lead Paint findings than the pressure problem. Finding the pressure problem is as simple as turning on the main water valve. You'll definitely find the leak once you do that! Don't let plumbing scare you, it's definitely not rocket science and fixing pressure lines are no problem at all. Generally it's much more of a pain in the butt to fix the hole in the wall you had to create to get to the leak rather than fixing the leak itself.
Make sure you find out about your Lead Paint Abatement rules in your municipality, though, as I can almost guarantee that HUD found lead paint in that house if it was built prior to 1978. Some cities all you have to do is have the paint in good condition with no peeling or flaking. Some cities are much more difficult, though, and require you to remove ALL the leaded paint using a lead paint abatement certified contractor, which can cost over $10,000! I know in my city, Milwaukee, there are grants available for this abatement which will cover most of the cost if you qualify.
