Wavy Floor Solutions?

[Jinwon H.]

I bought a duplex as my first investment property and to house hack. My husband and I are doing most of the work on our own and we are learning a ton.

My plan was to replace the carpet and sheet vinyl to LVP throughout. But after we pulled the baseboards and the flooring, we found out that the floor is wavy and uneven. Low spot is about 1/2" lower than a high spot.

We also found that the puddles form in the crawlspace when it rains, and it's very likely the flooring sagging due to structural damage from the moisture. We'll get the full evaluation next Wednesday.

As far as I understand, the right course of action is to fix the crawlspace and any foundational issue that's caused by the water, then install the flooring. 

BUT time is not in my favor. We (family of 4) need to move in by at the end of this month. 

So what are my options?

I considered pouring self-leveling cement and proceed with LVP as planned, but I wonder if that would cause the issue when we fix the foundation and possibly re-joist?
