My question is what insurance do I need to have to be covered for this property? 

Hi: To All 1031 Exchange Subject Matter ExpertsSo, last year I sold an investment property that carried a debt 800k.

Seller get $282k, buyer pay $300k.Option 2: Contact price $282k, the term change to buyer cover agent fee.

This also would include if your spouse has W2 though, so maybe you have this angle covered but didn't post about it 

Some outlets need cover plates installed throughout the premises.

Even if I were to pay or help cover the cost of remediation in the home, it would likely re-occur due to source being the neighbor.

If you are over 200 miles from home all expenses are 100% If you are just eating lunch in between stops it is not covered.

For my personal property, I aim to have enough reserves to cover "a new AC unit" per property should all of our AC units go out at the same time.

None of this covered by title insurance b/c seller won't allow it to be required for close.Next was the task of trying to talk to someone at the auction company who understands the import these issues have on the value of the property. 

Marketable title does not mean unrestricted... a property can be subject to restrictions such as CCRs, rights of way, easements and still be considered marketable.
