Most times just putting some type of secure cover on it will suffice as it's usually an insurance company concern.

If you don't have any credit yet (car loan, credit card, etc) a good place to start is getting a secured credit card with your bank, which should help you start building a credit report and score.

If the Line of Credit is secured against a piece of real estate that would help in most most cases. 

If someone else sends it to a Tax Deed auction, you get paid back plus your interest.If you want to force your Certificate to get paid back, you have to pay off all the other certificates, and send it to a public auction.

I just became a pro member a day or 2 ago and watched the webinar on multi families (I know there is more out there on the subject I've listened to Crushing it in apartments and commercial real estate by Brian Murray around 5 times now) but I just don't know if I'm suppose to go secure my finances first or look for a deal first.

I will be installing new security cameras around the area but that will only capture what has happened. 

The income is taxed as interest, which means ordinary rates but no self-employment (Social Security/Medicare) tax.

You can look most of that up, since it is public records!

Since as disqualified person you are not allowed to provide a personal guarantee for a loan to your IRA you may not use conventional loan, you must utilize non-recourse loan (meaning the lender has no recourse against you personally, property is the only security for the loan).

If you get a judgement I hear you can take money out of her security deposit  :-)
