wondering, holding us back, help

What happens if you get an offer accepted but can't find a buyer for that offer? How do you back out of that deal if you don't have the money to buy the property?

Also, do we look at each and every property we make an offer on?

How do you buy site unseen? Especially out of state?

When bird dogging do we make the offer and hand off? and when handing off the deal, how can you ask for a fee before handing off? what if buyer doesn't buy?
