I'm seeking your insights on two aspects of my two-family home. Your expertise and experiences in real estate investment and home improvement would be greatly appreciated.

Potential Layout Change: I currently live in the main floor unit, which is a versatile 1-bedroom but has the potential to be a 2-bedroom. The existing layout includes:
- A front entrance leading to a room with a walk-in and a coat closet. This serves as my living room but could be converted into a bedroom, as it has an existing door frame.
- Small Hallway to the adjacent dining room/off-kitchen area with a back entrance and a half bathroom.
- My small one bedroom room, off the living room
The previous occupant used what is now my dining room as a living room, and my current living room as a bedroom. I was considering knocking down the wall between these two rooms to create an open concept space. Would removing the option for a second bedroom in favor of an open layout negatively impact the property's value? Rather than favoring an open concept, one bedroom?
Hardwood Flooring Restoration: I discovered original 1930s hardwood flooring beneath the current layer of LVP and plywood. This same flooring is visible in my living room which I had refinished. I'm contemplating removing the LVP and plywood to refinish the original hardwood. This might require some TLC in certain areas, but I'm inclined to preserve the home's historical character. I was also told that the hardwood floor looks like it was never refinished before.
Would restoring the original hardwood floors offer a good return on investment (ROI)? If it's not significantly impactful ROI-wise, would you still recommend proceeding with the restoration for aesthetic and historical preservation reasons? Especially because I live in this unit and consider this my home? This decision ties into the potential wall removal, as it would create a unified flooring experience from the front entrance.

I'm not planning to move in the near future, but I am considering these changes with both current enjoyment and future value in mind. Your thoughts and advice would be greatly valued.
