(Honestly, $100/mo is not a safe place to be, from a cash flow standpoint!)

Best bet is to meet with someone face-to-face to explain your situation and see what they would be willing to do for you, I'd recommend researching and setting up meetings with a variety as it may take some time to find the right one.

And from there, you strategize or negotiate on what's favorable in terms, down payment etc. 2) 3-4% interest through seller finance is often times more safe/profitable for the seller as opposed to them taking their already 30%+ taxed lump sum of cash from selling their property and stashing it elsewhere to grow only on a fraction of the original amount. 

A new well needs to be drilled as the hand dug well is not viable/safe to use.

Your best bet might be to use a personal loan or credit cards for the rehab.

For example, what are some of the areas that are considered safe, clean and have good schools.

So if you know what you're doing then it can be a very safe way to get started.

Insurance seems to be the best bet to me.Foundation repairs are really not that complicated. 

House hacking is a great way to start and it will probably be your best bet.

At that price point I bet you can guess that almost everyone self insures for this risk.
