Gary,
The most valuable information comes from an expert, so you should talk to a mortgage broker. In this market there are different loan products depending on the property in question and of course the applicant. I can recommend 2 brokers that are experienced and reliable. It would be in your best interest to start forming a team that will guide you as you prepare to invest in your real estate future. This would be a great first step. Here are my recommendations in LA. Caroline McPherson with First Capital(310-260-8213) and Jennifer Lowe with Metrocities(323-273-7326). Good Luck. If you have any other real estate questions feel free to contact me.
