As to your plan of selling 5 properties in different states with seller financing, you still have issues with Dodd-Frank, selling to homeowners, exemptions are not deals done per state but by the owner and none of yours are owner occupied dwellings, you're in the business.

Lincoln,Liron is correct, if your property is vacant, you need a vacant dwelling policy.  

@Manolo D. Well

Unfortunately, they don't do insurance policy for landlord.My LV property was still insured for $288,000 dwelling last year.

(A) A landlord who is a party to a rental agreement shall do all of the following:(1) Comply with the requirements of all applicable building, housing, health, and safety codes that materially affect health and safety;(2) Make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition;(3) Keep all common areas of the premises in a safe and sanitary condition;(4) Maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances, and elevators, supplied or required to be supplied by the landlord;(5) When the landlord is a party to any rental agreements that cover four or more dwelling units in the same structure, provide and maintain appropriate receptacles for the removal of ashes, garbage, rubbish, and other waste incidental to the occupancy of a dwelling unit, and arrange for their removal;(6) Supply running water, reasonable amounts of hot water, and reasonable heat at all times, except where the building that includes the dwelling unit is not required by law to be equipped for that purpose, or the dwelling unit is so constructed that heat or hot water is generated by an installation within the exclusive control of the tenant and supplied by a direct public utility connection;(7) Not abuse the right of access conferred by division (B) of section 5321.05 of the Revised Code;(8) Except in the case of emergency or if it is impracticable to do so, give the tenant reasonable notice of the landlord's intent to enter and enter only at reasonable times.

By using an extra bedroom or units in a multifamily property to rent, house hacking can turn a home that’s already owned into a property that generates rental income.Here are some common strategies people use when looking for a home to house hack:Multifamily housing where one unit is a primary residence and the remaining units are rented to tenantsSingle-family homes with multiple bedrooms that can be converted into a self-sufficient suite by installing a bathroom and kitchenetteHouses with areas easy to convert to bedrooms, such as homes with a den or playroom that can be turned into an additional bedroomHomes with the basements, attics, or garages already partially remodeled are good candidates for house hackingProperty with a large lot suitable for building an additional dwelling unit (ADU), which is a free standing dwelling similar to a guest home or in-law unitAll the best!

With respect to single family dwellings (1-4 units) owner or non-owner occupied, HUD has jurisdiction over any state law.

STRATEGY THREE: ADDING ACCESSORY DWELLING UNITS (ADUs): ADU’s or granny flats, are a separate residence on the grounds of an existing home or apartment building.

There are 4 reasons to require tenants to get renter's policies.1) Liability, if your tenant is legally responsible for anyone's financial loss (injury, slander, property damage, etc) AND they do not have means, YOU may be pursued as additionally liable. 2) Structure Coverage, your property improvements if damaged beyond wear and tear by your tenant may be covered by your tenant's liability coverage instead of your dwelling coverage.3) Contents Coverage, not all Landlord policies are the same in the provision of contents coverage for tenants.

(from our Property Rules Addendum)Tenant acknowledges that it is necessary for Tenant to maintain appropriate climate control, keep the dwelling unit clean, and take necessary measures to retard and prevent mold from accumulating in the dwelling unit.
