He's mostly late in paying the rent, emotionally unstable and troubling the neighbors, has caused damage in the property, etc.

Once you finish the basement there is that much more square footage  that can be damaged and needs to be fixed between tenants or selling.

I could sue you right now for property damage because you crashed into my car.  

They owners assume that there is a redemption period and that they can come back after the sale and restore the property to them.

You should provide an itemized list of damages and charges that add up to the amount you withheld.

Therefore, if the move-out date is within the first 6 months, Tenant agrees to pay to the Landlord an early move-out charge in the amount of $2600 to cover the Landlord's expenses in having to re-rent the Leased Premises in lieu of paying the Landlord's actual damages.

The investor wants TLC properties or fixer-uppers with moderate damage ($10,000 to $15,000).

My personal strategy is to focus on B,C neighborhoods, to find the best possible rent to cost ratio within those areas, and then hopefully have less back-end cost, maintenance, vacancies, evictions, damage, vandalism, etc.

Next comes non-finish work that can damage finished surfaces.

Will also put down a security deposit in case anything gets damaged.
