Any advice, suggestions or recommendations to honest investor mindset realtors in these markets would be greatly appreciated!! 

Florida is a unique state for MHP law and the insurance has gotten very expensive there too.I recommend checking out @Frank Rolfe's mobile home university content if you haven't already.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I'm a little biased (am the owner) but seriously pumped to see you recommending it.

Can anyone recommend some stand up lenders I can speak to?

Consider starting with a few lower-cost flips with a smaller loan-to-value ratio to reduce financial strain.Market Research: Sacramento can be volatile, so I’d recommend keeping a pulse on local trends—particularly in the neighborhoods that have potential for growth but haven’t quite hit their peak yet.

.), I'd recommend that the residential units fully cash flow the loan as my experience is that mixed use properties are tougher to finance as most lenders tend to prefer one or the other and something in the middle gets more difficult.For example, and granted I don't know anything about the area/neighborhood, I would expect this property (https://www.realtor.com/realestateandhomes-detail/111-NW-Har...) to be easier to finance than the mixed-use property you mentioned. 

It's hard to harvest equity on these plays, unless you commit, long-term, towards very light leverage, as the only practical ways to benefit from the equity in your portfolio, if you plan to never sell it, only exchange it, for a lifetime, are to spend the cash flow, or cash out refi.

May I recommend that you find a local businessman/dentist/doctor to fund your flips?

Thank you for coming back and clarifying it, the minor difference does make a difference to me in practice.
