He took 5 days to send me a "cancel" agreement after lot of frustrated emails back and forth. 

I have literally run hundreds of APOD calculations in my home state and getting incredibly frustrated.

That's frustrating, and if you tell the agent "hey why don't we wait two weeks for that to close, so we can close two weeks late but be more certain of no appraisal issues" they will start getting prickley about their paycheck being delayed a few weeks.

I speak to a lot of frustrated landlords who have 5-10 c class properties.

It seems incredibly frustrating.  

Overall, it was a frustrating experience.

those are fabulous terms if you can actually get it done... lenders are very very particular on these loans and most folks get pretty frustrated with them.. its not like conventional were If you qualify they do the deal...

Frustration leads to just dumping the property to the next buyer at lower than market price.I cannot end on a bad/negative note.  

I take advantage of it and I understand why others (non business owners) get frustrated by businesses getting to write off so much.

Ticor, Fidelity Fatcoetc etc. its only on the East side were you have all these little mom and pop closers were you really need to watch out. or the off shore companies that have taken the business to India.. these are frustration as well
