OK.... My opinion.
1. My financial advisor does not invest in real estate but has clients that do. (OK)
2. I don't pay him a direct fee but he is also my life insurance guy so he gets paid from my policy. (Doesn't seem like he has a vested interest in discouraging you from real estate unless he is pushing you to further fund a life policy with what you would otherwise invest in RE. FYI... I really dislike insurance policies that are disguised as investments. Just get a term life if you need one, otherwise it is probably one of the worst investments (and highest fee) purchases you can ever make.)
2. My 10 properties cash flow at least $200 per month per property, some properties more than that. (This is an issue! I'm not sure if we are talking 250k properties or 50k properties, but I don't like those cash flow numbers either way. Any rent rate declines, vacancy, or repairs (roofs, plumbing, etc.) will put you cash flow negative really quick. Not the purpose of this thread, but I would reconsider your investment strategy if this is all you are cash flowing per deal).
3. My wife and I have W2 jobs with a combined household income of $450k, not including real estate investments. (This is a positive depending on (1) job security/income stability and (2) your current lifestyle. If you have significant reliable cash flow from your W2 AFTER all of your personal expenses this can provide a cushion/bailout if your RE investments get into trouble.)
4. I have over 200k in a 401k, another 200k in cash value life insurance, and another 150 in a HELOC. (Not liquid and major penalties)
5. My properties have a combined 500k in equity. (This is good, but that is not liquid funds, and liquidity is what you need if things go south. You can't fund cash flow deficits with equity.)
General advice.... If you are consistently banking a large chunk of your W2 income and it is reliable then I think you are likely fine. If the market turns, you simply stop banking your monthly income surplus and use your W2 to fund real estate investment deficits. Things could be painful, but you could likely weather the storm.
If you do not have a significant w2 income surplus, then I would suggest de levering. Sell your worst performing properties and use that equity to reduce debt on the best performing existing ones. Then strategically find other deals with a better cash flow margin.
My biggest gripe with what you describe is the $200 month cash flow per property number. You are taking on a lot of debt, risk, headache, etc. for a measly $2400 month cash flow. You would be better off buying a REIT.
