How much do they cost to replace?  

The middle piece on the living room window is foggy and needs to be replaced.

I made minor repairs to mechanicals and replaced an aging garage roof but didn't really invest much else.

I like the 1031 exchange idea, but the time frame to identify and close on the replacement property makes me nervous.

While Zoom is OK it's not a replacement.

Etc.I like that they say, the money can be used the it best alleviates economic injury .. that sounds like it is pretty much left up to us to determine the best use since the owner of the business knows best what they need.Perhaps, but it specifically states it cannot be used for repairs or replacement. 

* Did a complete gut rehab of the master bathroom down to the replacement of the subfloor, * Did a kitchen rehab by repainting the cabinets, adding new countertop, new backsplash and new appliances, new fixtures, * Repainted the entire house* Added new floor to the basement living area.* Added siding to the one extra room.

In practice, I have seen roofs that were well beyond their service life and needed immediate replacement pass a conventional appraisal without being mentioned by the appraiser.

I'm looking at using Formula Roofing to replace my roof and install a skylight in my rental property.  

We always do a final QC walk-through BEFORE we allow any prospective tenants inside, then we do a walk-through with the tenant when we hand over the keys to notate anything pre-existing, such as damaged casings, frames, etc that weren't in need of replacement.
