Rhino is an insurance program, and I do not recommend them.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

You have the mortgage, taxes, insurance, maintenance, capital expenditures (roof, flooring, etc.), and also need to consider the cost of vacancies or bad tenants.I also recommend you charge market rate, for yourself and the tenant.

They don't all offer the same servicers (default management, document services, tracking of taxes and insurance, escrows, etc.), but I am with you that communication and competency are key.

Feel free to use this template:RE: RenewalDear Tenant:With the increased cost of taxes, insurance, maintenance, and other incidentals we are required to increase your monthly rent.

Yes you have insurance, but it may not cover everything.

Are there dogs in the yard when you have a no-pet policy?

This is accomplished with an excellent team around you including an investor friendly Realtor who ideally is an investor themselves, property inspector, property manager, insurance agent, and asset protection and business attorney.

Also, we'll need to know what your other expenses will be (taxes, insurance, etc.). 

I believe solid insurance and a good umbrella policy will suffice.
