Floor vents...move or stay?

[Denise Chester]

Hi BP fam!

I have some questions that I hope I can get your help with. I did a walkthrough on a potential rehab today. The house is in FL and was built in the early 80s. I noticed that the AC vents are located in the floors. The first time I've seen that in a SFH. My first thought is that although they may be functional, for resell appeal it would be best to have these re-routed to the ceiling. Now I have no idea what the cost would be, work involved or the necessity of doing it. But for me, it would be a sticking point as a retail buyer. Also, redoing the floors is a part of the rehab. I'm not sure of the challenges of having floor vents pose when installing new flooring. Thoughts? Is moving the vents necessary? Am I putting to much personal preferences in this? Thanks in advance!
