I don't think it's the banks. In my view, the problem lies with demand.
Not three hours ago I received a call from someone who wanted to meet and show me his business plan, in anticipation of borrowing money. (A business plan is always the tip-off.) After a brief conversation, I learned he has no deals and no money, but a plan to get into flipping. He wanted to borrow the purchase money from me (100%, naturally) and borrow the rehab money from "his investors." Of course, I politely refused.
I'm receiving more and more of these calls in addition from those who are buying at over 75% of ARV using some pretty severe hard money. Last night at a RE club we met someone who is flipping two houses with two loans each and said she will likely lose money. She shared that regretfully, she wanted to get in so bad, price didn't matter. I know the room was filled with many like her.
Five years ago it was no money down on pre-construction. Today it's REO's and short sales. I really believe we're in a small flipping bubble that won't last for everyone. Meanwhile, the wannabes and over-payers are driving prices to ridiculous levels. The banks, which seem to have an infinite supply of shadow inventory, could fuel this bubble for a long time. As demand increases however, I can see them releasing more inventory thus stabilizing or reducing prices. Or, the neophytes will simply put themselves out of business causing prices drop. Problem is, there seem to be a lot of neophytes.
