Roughly how much are you looking to borrow?

Same problem if you are making owner finance loans from the 401k, and the borrower decided to sue the 401k as lender, alleging a violation of Dodd Frank or whatever. 

If A - then you have to check with his employer regarding the requirements for borrowing from his 401k.

Another thing that is pretty typical about banks is their 20 to 25% down payment.One other thing that I forgot to mention was that the multi-millionaire can only borrow from a Bank is 4.5% and that he plans on profiting 150 million this year. 

Start off low and renovate as they leave and maybe keep increasing the offer amounts if people stop leaving.This is a great find, if you find any more like this shoot me a message!

I think if you take a HELOC that would count against your Debt to Income ratio and might affect your borrowing capability.

Obviously no one was paying rent but they took the rehab money, never did the rehab and then sent $650 checks each month til the music stops.

As @Michael Jones has mentioned it shouldn't stop your investment consideration if it still makes sense. 

If I borrow 700k (550k for purchase, and 150k for rehab) at 25% down, that's 175k, and that leaves enough for closing costs.

I feel your pain but think of it this way now you can get a long term tenant and stop working so hard.
