Need advise on moving some walls / egress

[Les Key]

Just acquired a property in a small North Texas very rural town. No building inspections or permits exist out there. The previous homeowner enclosed the back porch and was using it as a 3rd bedroom. By doing this the only window from the 2nd bedroom egresses into the enclosed space. I could probably rent the house as-is but I would hate for it to be an issue if there was ever a fire or something drastic. I'm considering shrinking the enclosed porch to allow egress from the 2nd bedroom window to the outdoors.

Looking for some thoughts and guidance. None of the walls I'm shifting around are structural so no issue there but from a leasable / liability stand point what are your thoughts?
