Make an insurance claim and buy all new stuff.

In my home market of Florida, our insurance rates have made it much harder to have positive cash flow on a CRE deal.

Insurance liability, I personally know 2 families that lost their children in home pools.

A good property manager can help with tenant screening, enforce lease terms, and handle evictions more efficiently if it comes to that.Require a Larger Security Deposit: Within the bounds of local regulations, a larger deposit can provide a cushion in case of damage or unpaid rent.Consider Rent Guarantee Insurance: Some companies offer insurance products that can cover lost rent in case of tenant default.

For example, we need proof of renters insurance and proof they put electricity in their name.So, it seems odd that you are accepted but they keep wanting more information. 

Quote from @Erick Pena: A "good" rental property is one that covers all expenses (mortgage, taxes, insurance, maintenance, property management fees, and any other costs) and still leave a surplus (commonly referred to as cash flow).Calculate cash flow as: Cash Flow = Rental Income − Operating Expenses − DebtThere's much more to it, but that's the basic idea.

Also, keep in mind if it causes an undue burden on you or is too costly you can deny them. for example, if your insurance company says that dog breed is on the ban list then you need to find out how much it will cost to insure them. if the rates go up because of the dog then you can deny them based on the undue burden. 

Always let the seller know verbally as well as include it in the Purchase Agreement that they WILL be responsible for Title insurance and any related fees, as well as any back taxes owed.

.- Tell them they'll have to provide you with a copy of their renter's insurance naming you as additional named insured, with a minimum of (I use $300,000) liability insurance, also before they move into the unit.It's not perfect, but it's a start toward a tenant transparency.

You'll want the rents to at least cover the monthly principal, interest, taxes and insurance (and HOA if there is one).
