Like deferred maintenance, (bad roof, worn out water heater/AC Unit, warped flooring, water damage) etc, unpaid utilities,  unpaid taxes, a second loan, unpaid HOA fees, a bad pool, bad reputation, sometimes squatters, sometimes they were drug houses, and so on.

An attorney is not needed provided your not making a claim of fraud or misconduct/damages are being sought. 

@Polat Caglayan very ambiguosu question, but read the helpful info below to guide your next set of questions:)-------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

They are far more common now and harder to find models without but:1) these add cost to the purchase price2) they don't bring a lot of value3) they can leak or detach and damage the propertyI own around 50 doors and I cap off the line at the wall or in the basement with a valve and a cap so the potential for leaks is 0.00001% :-) 

I have lost a lot more $$$ to tenant damage than to unpaid rent.  

Renting out mobile homes can be a great source of cash flow but they’re notorious for being damaged significantly by tenants and tend to need a good bit of repairs before renting out to the next tenant.

Despenas LLC aka SDIRA Wealth aka Modern Day Living Real Estate LLC are all scam companies that inflate housing prices in the neighborhood only to sell eviction-prone extremely damaged homes with no intent to perform the agreed-upon inspection repairs and send you through multiple corporate hoops after purchase only to completely ignore you immediately after the sale.

Personal Liability: For claims due to Bodily Injury or Property Damage that you becomeLiable for and which is covered under the policy.

However, I definitely recommend pictures any time a guest left damage or extra cleaning that will result in additional charges.
