That said it is not the sellers fault the bank fell through as well and is unfair to them. 

Last time I saw this I was in Greece in 2007, learning the flip game in an environment so out of whack that after the bottom fell out of the giant Ponzi scheme that the country had become, the Greeks were forced to admit the situation would take generations to fix.I'm not going to cry doom and gloom.

The property was under contract but the contract fell through as the seller would not be able to get the property rezoned and turn the large bonus rooms into another unit, making the property a quadplex.

That market fell for about six years basically from 2006 to 2012 it may be four to five to six years but nonetheless call it five as an average.

The property is in need of heavy renovations (repair a brick wall that partially fell/collapsed, new roof, etc.).

If I were going to allocate millions to redeveloping a building that fell into the above category I would not want to do it in a C/D class area.  

Arizona fell the hardest in housing bubble crash in 2008. 

Alas, it fell out of escrow when he couldn't get qualified (I was owner financing). 

Hello,My rental ad on Zillow rental manager did attract multiple prospective tenants but they fell under the following four categories:1) Tenants with pets2) Tenants who were bargaining a lot.3)Tenants who had weak financials but willing to pay rent inspite of their income well below 3x4) Few tenants whose profile good on surface but their phone numbers were flagged as "scam likeli"I personally am not comfortable renting to all the four categories listed above so it has delayed finding a tenant for me besides I haven't been very aggressive pursuing tenants as I had plans of selling .Now I have decided to postpone selling, what are the other best ways to find tenants quickly.

I am surprised by your comment on Bridge @Nathan Brooks is one of the most respected individuals in the industry.. maybe something fell through the cracks and he will want to know about it.
