We're competing against cash buyers, dealing with properties that have rent control and inherited tenants, and we had a few rejected offers.

I'm going to assume that any realtor worth his salt is going to advise his client to reject an offer with any out of the ordinary contingencies.

If they balk at the amount reject their application.In reality you should not be taking deposits to hold.

I also wanted to confess that I have already been rejected a loan because I lacked documents to be issued one.

The owner has rejected several offers that have come in below asking price and is dead set on his price.

I offered 35k cash and was rejected no counter.Property been on the market for a year now.Was just reduced 5k this week?

Him and his Barbie ex wife are probably just B actors rejected by Hollywood.I prefer the old school construction reality TV like 'This Old House' or 'Hometime'. 

Crunch numbers on deals and when you've done that for all the deals in your area and are bored, start getting your documents together: Tennant pre-qualification list, rental application, rejection letter, lease and addendums, etc...

"So this was fairly easy denial"I agree 100%, I would reject without a second of hesitation.

This problem does not exist with efile, practitioners get notified of acceptance or rejection usually within an hour for a federal return.
