It is not necessarily that the bank will automatic deny the loan, but does increase the possibly, so why risk it.Big regional and national banks are more fixed in their ways and therefore less flexible to the needs of some of their customers.

Flipping is extremely hard work, feast or famine, and subject to market cycles (there's no denying we are at a market peak right now, and none of us knows how long it will last). 

Then start looking for a few things.Vacant home (you can tell from pictures)Probate or estate in descriptionHouses that need workI feel like people start freaking out around the 90 day mark and may start to entertain offers they previously would have denied.

It's not like you ask once, get denied, and can never ask any bank anywhere for a loan forever. 

They are denying because they say it is "not rented now" (lease expired) and hence I am not actually recognizing a loss.

I was told that there is no termite activities therefore, they dont do any treatment. so there was no treatment done since I lived there.Now, my agent is telling me I have to get termite treatment because they found old termite damage even though  there isn't active termite and other wise, loan will be denied.

Is there data that might confirm or deny this?  

If you have enough liquidity, I don't see why anybody will deny you - also assuming you have substantial savings and a good credit.

You don't have to do all these things but if you do you won't have to worry about being denied, possibly losing earnest money deposits etc.

I spoke to them, and they said that they will deny covered to any dog that has bitten in the past.
