Inspectors told us that we need to install 4 fire rated windows by the fire escape because the property is commercial...where can I get affordable fire rated windows / glass?

Just put in the new windows on the fix & flip in Tulsa.

@Elton John - I'd go to Star Hardware in Hartford and ask them who buys a lot of windows from them and see if they can give you a phone number.  

Quote from @Enrique Toledo:If it is just window seals yes list it now.

You do not have a 5-year window after moving out.

Situation:
We have a home we used to live in. Our tenants are moving out, and we have until this time next year to sell and still qualify for the primary residence capital-gains exclusion (IRC §121). If we re-rent it...

Just windows, electrical receptacles etc.  

I look for moisture around radiators/baseboards, bathroom fans, GFCI outlets, window guards, fridge door seals not cracked (tenants will never report this, your electric bill will), under-sink P-traps for slow drips.

You will get increased rent and also lease out the property quicker too with mini splits verse window units.

Even if the window/doors are not a common element, I would reach out to the HOA and request a copy of the contract between the HOA and the landscaping company.
