I call them back and say don't you think a whole sale slip profit for 90k Is excessive.. he stumble bumbles and can't really answer..

As @Natalie Kolodij mentions, there are special rules for "self-rentals", an example is that you cannot deduct rental expenses in excess of your rental income. 

California charges a minimum tax of $800 a year per LLC, and more if you have gross receipts in excess of $250k. 

Examples would include excess assets you can collateralize, another property you can pledge etc.  

Let them know you intend to hold them liable for the lawn damage and excess utility use.

I think some landlords make the mistake of taking deductions without proof, without receipts or they charge excessive amounts.

Now it has come the moment where I have to place a value that will be removed from the Security Deposit.Overall the property is in "decent" shape, except for a few things such as:- Tile grout are excessively dirty.- Patio door lock had to be replaced.

But as someone who started out with negative 80k in net worth and now has an excess of 4mil its NOT easy and there is NOTHING glamorous about cleaning / fixing toilet's, paying bills for repair costs because a tenant destroyed a property, or dealing with a bad tenant or HOA, going to work for 8-10 hours at your day job and then going back to work again for another 6-10 hours on your RE, giving up vacation, fancy cars or clothes or dinner, Being covered in paint and drywall dust after working 16-20 hours knowing your just going to do the same thing tomorrow and next day and the day after that.

Other than that, normal wear and tear is on me, and charged to tenant if it's excessive. 

Suburbs have an excess of units since many have moved back into the city recently.
