I went with top of the line windows - Andersen wood sash casement windows - so I dropped about $30K just on some windows.  

@Justin Woods This is a good place to start.

I understand the 1% rule as it applies to charging rent but it seems unrealistic in our neck of the woods.

Turns out, wood paneling can be a look if you design around it and put enough Old English on it!

Paint the wood trim over fireplace the closest beige to blend with the brick color, remove dated fireplace screen and stage inside the fireplace with staggered candles, or photograph while fire is roaring inside.

If there's any question about it, get an inspection, and a quote or two to fix (termination and replace rotten wood) asap.  

@Mike Wood Thank you!

@John Woodrich Your neck of the woods is my home away from home.
