The standard FARBAR contract has an inspection contingency.  

I saw a lot rental listing has this "deductible" thing, I'm wondering if how many of you do that?

What is a good or standard target profit margin from a wholesalers' point of view?

-A standardized state contracts (from the state RE association)?

@Sean O'Connor $970 a month was the standard w/o utilities. 

Can we deduct from the money they're paying for rent, then deliver a late rent notice because it's not paid in full?

Some are flat-assed broke and very poorly run (no sarcasm on that one).Technically you should have been able to review those docs prior to closing, and even now after you've closed I think it's pretty industry standard to to be able to access that info, but they may require you to jump through some hoops and pay for it.

and its unnecessary and anyone doing business with you should know that. what you did wasnt creative marketing, you offer your self up as a professional you should be made to adhere to standards. 

After registering, properties are inspected every 10-ish years confirm they meet basic maintenance and safety standards. 

Where I live I am not able to deduct the principals payments I make on my mortgages, only the interest.
