Right now, for the liability coverage, we have an umbrella insurance in place. 

You'll definitely want to make sure you have some waivers put together if you go that route though, as well as getting the appropriate additional insurance coverage for using the boat as a rental.  

My normal insurance provider(Erie) said they will not provide coverage on a rental we are about to purchase due to the home having fireplaces.

Opt for landlord-specific coverage: Ensure you have a policy specifically designed for landlords, which may offer better rates and coverage tailored to your needs.3.

Usually only business purpose mortgages (DSCR or debt service coverage ratio) or non-conventional (Non QM) permit the contract and closing to occur in the businesses name. 

With 30% down your options are thousands of lenders.Why is it unwarrantable- master policy not enough coverage; low occupancy rate; HOA reserves; cannot be rebuilt or repaired; pending lawsuit in the less than 10 year after built for construction defect; flood zone with no flood policy...?

Here is what I am seeing right now around the Boston area:Flips:LTV - 75-80% is what I seeOrigination Fee - 1/2 to 1 point feeI look for 100% coverage of hard construction costsInterest rate - I’m between 4.25 and 4.75% at about 6 local banks right nowTerm - highest is about 18-24 months.

Checking my deductible but I will take the experienced advice here - will check with insurance but will refrain from claiming if it impacts my coverage. 

Quote from @Jose Ramirez: I wonder if anyone can give me your feedback on umbrella insurance State Farm called me and told me that I should open a umbrella policy for my rental properties Most umbrella policies don’t cover business pursuits, nor losses from having too low damage coverage.

If your insurance coverage isn't enough, they could seize the LLC assets, but not your personal assets.Additional thoughts:1.
