Hi Thomas, You'll find investors in your area by searching deeds of trust filed, just look for individual names, private trusts, such as the "WIlly He Loanya Trust, dtd 3-15-98" or small entities that you know are not institutional lenders such as Loanya LLC.
How to approach any lender is basically the same, you need to address capacity to repay the loan, credit and collateral offered. You need to really stress capacity and show your exit strategies if things go sour, from losing you tenants due to radon gas to you dropping dead. They must be assured that they will get their money, most individual "investors" who consider moving money from their money market account to you, don't want to consider having to take the property and selling it to get the money. To solve this problem, you might consider having your loans serviced by an independent loan servicer. Good Luck, Bill
