Just to really drive the point home on how easy most of these owners are to find if you're using a true quality skip trace service, feel free to message me and I'll personally run a couple for you and send you full reports on the owners and possibly the owners' relatives if I see anything that makes me think you should be contacting relatives.  

In turn the seller can take action against you because there is an agreement between you and the seller.This is true UNLESS you did this deal as an actual "assignment" and the contract between you and the seller has "or assigns" as the buyer and you notified the buyer of the change in buyers prior to the deal falling apart.

If anyone can advise me if this is true or I should try harder to find a lender who is willing to, I would appreciate!! 

Quote from @Branden Rivero: The issue I see is the building is close to 100 years old and with a $500 hoa it's not an easy sale for an investor Yes, thats true however all expenses the past year increase insurance, sewer, trash, electric and cleaning service.

Is this true? 

Is that still true?

Appraisal Value & Financing: While it's true that ADU appraisals lagged behind costs a few years ago, the market is quickly catching up.

This is particularly true because you don't have turnover expenses in there either -- which you will need.

I've looked into 15 properties, all of them show negative cash flow, is that true ?
