I will usually walk the property with the inspector and my General Contractor so that he can confirm or adjust my Rehab estimates.  

They are adjustable rates and balloon after 10 years.

It's a real pita to keep it clean, check the chlorine and adjust, check the ph and adjust, add water when necessary, clean the filter, vacuum the inside, remove dead bugs and leaves, and this is only 20 feet from my back door. 

Typical 5 yr calls and rate adjusts?  

You need to know this so you can adjust your offer accordingly. 

We stair stepped the rent up each month to give them additional time to adjust or find new housing.  

The insurance adjuster has one goal (guess).

@James MarshallOrdinarily, you would be right, but only if the FMV value is less than the adjusted cost basis.

It is going to be looked at as you signed a contract, decided to do repairs on your own and then made a determination of what you felt those repairs are worth and adjusted your rent on your own with no approval from the owner of the property.Many areas have a place where you can pay all of your rent and then file a grievance etc, which would be the way to go.

You may adjust depending on the market when the leases come due.
