Updating Condition Checklist Mid-Lease after Updates

[Jeremy Rusnak]

Hi all,

What is the best way (if any) to handle updates to a tenant's property condition documents after they have already moved in?

One of my rental properties was built in the early 70s.   Many of the windows were missing screens and the windows difficult to operate (or not at all) when I purchased the property.  The status of those windows is noted on the tenants' condition reports they signed when they moved in.

I have been doing upgrades to the property and just replaced all the windows.  I'm concerned that without a new signed document from both parties when move out time comes I may have no recourse if there is damage that happens from this point forward.  

Can I create an addendum that the tenants sign stating that all windows are in new condition?  I don't really want to redo the entire document since there are a few damage issues that would already be charges on the old documents and that seems a little messy.

I'm curious how other people handle this, or if I could run afoul by asking residents to do something like this.
