Myrtle beach is in high demand, Matter of fact I am currently in an ocean front unit 10 min south of Myrtle Beach, Garden City, 

With 5 units on 4 properties, it sounds like you're single family heavy buying highly distressed properties that take time to renovate. 

They are highly encouraged with financial incentives to get renewals. 

We have a network of highly qualified and vetted subcontractors that we work with.

Given our financial constraints at the time, we couldn't afford such a high sum for limited coverage.I'm told that the lapse in coverage for the few months between being dropped by our previous insurer and attempting to get a landlord/investment property policy will make if VERY difficult to get a policy.I'm not sure that my agent really has much experience in insuring investment properties/rental properties.I reached out to Arcana (now MSI, and they forwarded my a list of agents/reps that could work with me.My question is: Are there any other places I should be looking to obtain coverage?

You'll have higher out of pocket costs for inspections and appraisal on 5+ units, LTV typically doesn't go as high, many lenders require a 70%+ occupancy rate.

I have a high credit score and zero debt; I just don’t have the work history.

With the high property tax and about 10k of work needed on the home.
