I have just been notified that there is extensive damage (an unteported leak caused by one of the tenants bidets) and an unauthorized pet in my rental home that may have also caused damage.

One lost deal/repossession/bankruptcy and credibility is damaged.

The Unethical thing that you could not do that may be considered illegal is if you in some way destroy or devalue the property since it is an asset to a senior lien holder and they may suffer as a direct result if you do any damage.

If new broker says they can't list, ask them to provide written documentation why they won't, as it could help you in any court case against you or your house if you can say the wholesaler has damaged you by you being turned down from listing and selling your house at a fair price once you understood their scheme and let it expire.

You could end up with multiple inspections being done before even going under contract, inconveniencing the sellers and potentially causing property damage from invasive inspectors, hurting the listing and keeping the property on the market longer while the issues are resolved.

Its more so they can communicate concerns or issues with me if there are any as well as not be held responsible for potential damage that was not caused by them.Is this common practice? 

Umbrella Policies are good, but they are not an asset protection tool, they only cover litigation/damages after you’re already in litigation or found personally liable.

Landlord provides tenant (at tenant's decision) the option to limit potential damages by agreeing to pay 2X rent as lease break fee".

. :)  Keep in mind, that YES they are more expensive AND, they may actually get small "dimples" in them from hail... it will show (in many not all) forms of metal roofs but that is NOT covered by insurance (cosmetic damage). 

.- Single family and multi-family properties means that the investor takes a significant (or all of the) exposure on the property in the event of damages and repairs while with a condo such costs are shared.- Condos are typically closer to very busy areas like city centers (while single family and multi-family are further away / in suburbs) which, in the case of a buy-hold-rent strategy, means that the investor will have more traffic / demand.- Smaller properties are usually easier to off-load (more liquid) because our society is seeing very high levels of migration (people travelling or moving for work constantly) / people less inclined to partner / have families / people more focused on work / and pied-a-terre concept.- Condos are much easier to maintain internally than larger homes.- Condos are easier to manage as Air B&B than larger homes.- In the case of multi-family properties, sharing a home with two or three other families where everyone knows everyone can create issues if they don't get along as the close proximity doesn't allow for any privacy.Happy to connect with you and speak in more detail if you are interested in Massachusetts!
