Anyway I punched in real estate and it brought up a lot of books on the subject. 

Diversity is the (not so) secret to reliable income from investments.

There have been cases shown and decided that a "chain of events" that led up to the closing and sale had the buyers broker / agent earn a commission.So a lot of it is subjective as to what happened, how it happened, and at what time.If this is a smoking hot deal and they are going with your offer and it's a low sale price then another option is to let them double end it and get a real estate attorney for 200 to 300 to negotiate the purchase and sale for you.

McGuigan you will find in life and business that some relatively bright people will have different and seemingly contradictory opinions on a given subject, study read and learn as much as you can, then see what makes sense to you, take an idea concept, try it, push it, test it see what works and what doesn't for yourself.

The home in question is your primary residence and is subject to short/long-term capital gains tax, not business income tax.

With frivolous suits, an attorney will typically do a quick check to see if the subject of the suit has any easily attachable assets. 

You need to find out an acceptable price that you can pay her subject to her being able to get a loan to buy your property.

Also, if you're looking to get into a property with zero money down, you're either going to have to find a private investor, get a seller to do a carry back either as a 2nd or as primary financing, or try to get a Subject 2 deal. 

If you spend some $ marketing you might be able to purchase a property subject to the exiting mortgage.  

@David Stergiou  I think there is a pod cast on the subject.
