Kirk,
I agree with what Ryan is telling you all the way. Successful investors make a lot of offers to THE RIGHT PEOPLE. Those people are motivated sellers. Those who make offers shotgun style to regular retail sellers are only setting themselves up for disappointment. Remember, if they are not motivated for whatever reason, they have no reason to give you good terms, a good cash price or both. And they won't. If they are not motivated, next. This is a numbers game.
Remember every no is just one closer to the yes you are going to receive, IF you stick with it. If it were easy, everyone would do it. If you make 100 offers consistently to the right people, you will succeed eventually.
Be creative and learn to love the chase and negotiation. That is where you make the money. No other business rewards those who can think outside the box or creatively to meet the seller's NEEDS than real estate. Eventually, it is more like a game to you. Once you release all attachment to the outcome of any one deal, you will start to come into your own. It takes time sure. But stick with it. It gets easier and talking to sellers is the best education there is.
Good luck
Mike C
