Luxury vinyl flooring on top of wooden flooring

[Peter Morgan]

Hello,

I have wooden flooring in my rental apartments, some of the wooden flooring was partially damaged in the living room and one of the bedrooms, I think I made some poor choices when hiring a flooring contractor as I was a total noob few years ago, it turned out the contractor ripped off the entire  bedroom

flooring and installed it with a prefinished flooring which is in stark contrast (a lot darker) with the rest of the apartment and he installed some of the ripped off pieces from bedroom  and installed in the living room to match color but it feels a liite bumpy around that area. Since I am planning to sell I am trying to find answers to the following questions:

1)Is it a good idea to install luxury Vinyl on top of the existing wooden floor for the best ROI?

2) How much does it cost to install LVT covering up to 1300 sq ft?

3)Installing LVT is that a DIY project or should I teach out a professional?

4)Any recommendations of stores or particular brands for best value?

I will appreciate your inputs. 

Thanks
