I was browsing the Real Estate Investing books when I ran across a book that had a card sticking out like a bookmark. 

( I’ve had good luck playing that card showing the owner the cost get the complex in compliance or buying contingent on it being compliant)-expenses seem a little light if it really is a somewhat run down property in a bad area ( depending on your investment strategy these properties tend provide better cash flow to somewhat compensate for the lack in appreciation)-are tenants paying utilities?

But, fi something happens, all the cards will come down.

It is like a credit card but attached to your property so the interest rate is not super high.

What I would start doing now ,while you are in school and putting money aside for a down payment,  is to get yourself one credit card.

IRS auditors will want to see both a check and invoice/receipt or credit card and receipt. 

I used my HELOC, cash and credit cards to rehab 3 properties I bought in July.

Maybe opening a secured bank card for $300, using it for gas and for sure paying it in full every month.

Pay attention to @Sylvia B.Also, borrow on credit card but make it habitable and enjoyable by any tenant you choose. 

If they do, I wouldn't pull the "trust" card out as they will roll their eyes when they accelerate the note.
