Ways to Market Private Money:

Get plugged in - Networking centric groups, such as BNI (Business Networking International) or your local chamber of commerce (if you have a good one) are a 100% must-do. Why pass up the chance to present your opportunity to someone each week who has a vested interest in finding an investor for you? Why will they help you find investors? Because you will, in turn, reciprocate and send business to them. The power of these groups is tremendous.
Partner up - Consider partnering with other real estate investors, often those with less experience, who may have private money sources. If they bring the money and you bring and manage the deal, everyone wins. You win, the new investor gets experience and the private investor wins. Be careful to lay out the ground work ahead of time, so the private investor isn't perceived to be 'stolen' by you. You may have to partner with real estate investor for use of their contacts money, but there are worse things, right? Think of the referrals you could get from a few deals like this and don't forget that you're making money on the deal as well as building your resume.
Professionals - Leverage relationships with professionals, like your CPA or attorney. Show them your business plan and investment details and let them bring investors to you. If you truly have good deals and strong returns, a referral from a professional should be in the works.
If you think that you don't have the time to tap into this hidden source of private money, guess again. In just a few hours spent per week you could have hundreds of thousands of dollars in private money referrals coming at you. When you have a good business model and a solid value proposition, economic principles dictate that money will be attracted to your door. All you have to do is open it.
