@Neil GoldmanA standard landlord policy on each property, with the maximum amount of liability coverage (should be at least $500k, some providers will go higher).  

I am looking for comprehensive training from one source.

From a financing perspective a key metric the bank will look at is the Debt Service Coverage Ratio (DSCR).

The pricing and coverage is great.

We are single family homes - so that coverage is up to the individual.

Let the title company take care of it and your deal,  transaction and settlement will be insured by your title coverage.

Some that they may use are:- requiring the dealership to name you as an additional insured on their policy - requiring 30 day notice of cancellation- requiring that the dealerships liability insurance is primary and non-contributory- requiring them to hold you harmless and indemnify youYou should check with your agent to make sure the Liability coverage you have for the Lot will not increase due to the new use. 

Serve a Notice to Enter to do a comprehensive inspection of the units for maintenance and repair.

Using a professional solution for online applications would eliminate the risk from those items, so I'd seriously consider using Cozy.co if you're just looking to start as I believe that's free to you, while AppFolio or Buildium are much more comprehensive property management platforms with screening features built-in.

Does anyone have a resource for homeowners insurance coverage for a vacant property I'm rehabbing in Massachusetts.Thanks Larry J
