Should I be buying homeowner's policy or landlord policy for my rental unit.

Trying to get an umbrella policy to increase my liability coverage now that i'm close to closing on my property in Florida.I have a 21 year old au pair from Brazil who lives with me and drives my cars and is covered under my geico auto insurance. 

This is once place an umbrella policy can offer coverage that general liability on an property can't.  

The solar panels may actually increase your insurance costs or create coverage gaps since they add roof penetrations and expensive equipment—verify your policy explicitly covers solar panel damage, removal/reinstallation after roof repairs, and inverter replacement.

Purchase price: $550,000 Bend, OR that we purchase at fair market value, for $0 down, seller finance over 31 years at 0% interest.Seller had house deep cleaned, carpets professionally shampooed, windows professionally cleaned, brand new AC (ducts, grilles, etc) this June.My total wire was $2,755.00, but that money is coming from a referral to an agent for another one of the seller's property.I have tenants moving in on a 18 month lease $2,795.00 and my PITI is $1900.00, before I make the first payment.

When you say "Cash flow after reserves: Run it with conservative rents + all expenses (PITI, mgmt, maintenance, vacancy).

Purchase price: $550,000 $0 Down … 0% Interest (Yeah...0)This week my family and I close a deal in Bend, OR that we are purchase at fair market value, for $0 down, seller finance over 31 years at 0% interest.Gets better...Seller had house deep cleaned, carpets professionally shampooed, windows professionally cleaned, brand new AC (ducts, grilles, etc) this June.My total wire was $2,755.00, but that money is coming from a referral to an agent for another one of the seller's property.I have tenants moving in on a 18 month lease $2,795.00 and my PITI is $1900.00, before I make the first payment.

Anything around $30K or more usually fits in the budget better under a COR.A Cah out refinance also put liquid reserves/Cash into your hand or into checking/saving and can be used for PITI "reserves" or assets required by most banks/lender to buy more REI properties and a Heloc can NEVER be used as an asset or PITI reserves.

The carrying cost vs rental income spread here is just not conducive to an investor of my size at this point.The rough numbers, if they'd help, would be a carrying cost of PITI approximately $1700 including landlord-specific insurance and moderate property taxes.

Any recommendations for a good Builders Risk policy for a SFR fix and flip in Austin, TX?
