What to do next so as to increase our wealth...?

[Aaron J.]

Just looking for opinions. I don't think I have the stomach for the rental business and risk in general but also understand that you cannot get ahead in life without taking some risks. As of right now, it seems as if we are at a standstill, with the exception of our home equity growth. I guess my question is what should we do next? We have no other debt other than our mortgage. Combined annual income is $75,000. Thoughts?
