My guess is that your tenant found somewhere to live, and want to break the lease and is looking for an excuse.

Contractors are more likely to get screwed by a homeowner or investor than you think .The most  Common excuse is " I am waiting for a draw "  .

Not making excuses but really had no education.

I told him that he had said 75% of the appraisal and he gave me some excuse about that he can’t sell the loan or get it approved. 

I need to go all in on myself and make no excuses.

You will be worn down to a little nub, and sooner or later, you'll be just another bozo in a house that costs too much driving a car that costs too much living a life where you can't pay off your credit cards (like 60% of Americans), caring about the financial judgments of your social status made by broke people, and making one excuse after another about why "I just can't get ahead...I just can't."

Piece of advice, as SOON as they are 5 days late, no matter the excuse, serve a 5-day notice and follow through.

Also to do away with the "lost in the mail" excuse.

Don't let your current location on a map become an excuse not to get what you want, it's a challenge I agree, but you have to meet it to succeed!

Plus, I could see people ending up doing things "half-***" (excuse the language) if they are still rehabbing, but the tenant has already said yes.
