If you generated a bunch of losses with pre-in service expenses then those were incorrectly accounted for, and should be improvements/basis items. 

My team an I hauled over 12 tons of items from the house, did a minor renovation, and converted the workshop into an Accessory Dwelling Unit (ADU).

It’s filled with items some of value, but most not.

Impact their credit score for other items they may try to do in the future. 

The contract states the seller should disclose off-record items.

For risker applicants, require a guarantor (who is not "judgment proof") to agree to pay for damages and unpaid rent.Unfortunately, you cannot eliminate all risks of loss, so there are times that a tenant may end up causing damage beyond the security or coverage you have to pay for damage, but the above items will help.

Renovations are high cost items 

Due to item 1, adding an ADU can require years to start achieving any return (once the accumulated cash flow recovers the initial negative position).4) Adding an ADU is a slow process.

Send him his itemized status of deposit within 21 days with your list of  charges, receipts,  Include any damage. and unpaid rent.

We may do something like this in the future so that we don't have to deal with the chaos of getting a new one when these items wear out...usually right in the middle of a guest stay.  :-)Hope that helps.Mike
