What happens in the office building when the majority tenant is sent into bankruptcy because of a bad management decision and they vacate your property?

Most will file bankruptcy or take a 11.99% rate with a 2 year prepay.

Have the seller file bankruptcy that stops foreclosure

However, in this business you have to take some risks (I just signed a lease on an A property with someone whose bankruptcy completed a couple weeks ago and they are currently waiting for the Sheriff to knock on their door and tell them to get out of their foreclosed home). 

I call it a "quiet bankruptcy" because no one knows but you, as long as you can meet the obligations with the income you generate, from any source, you don't need to tell the world you're bankrupt. 

I can help save them from going through foreclosure or bankruptcy. 

I need some advice from attorneys or landlords experienced in dealing with an applicant with an open chapter 13 bankruptcy.

Would it be in the bankruptcy file? 

The bond market is in a bubble due to fed purchases, record debt in student loan,auto and credit cards, the imf says 15% of listed companies can't affordthe payments on their debt, and this year has seen 65% increase in corporate bankruptcy filings, tesla has never made a dime, amazon makes 0$ on merch sales, etc,etcShort term buy and flips are probably a lot less rissk now.

Pick an income requirement, minimum credit score and probably say no past bankruptcies judgements from other landlords or evictions.
