I wouldn't leave it until Nov to deal with the drywall especially you are in an area where it is warm and humid (mold can grow quickly). 

Here in TX the soil is mostly clay, and it shrinks and expands with humidity level (thus the need to "water the foundations" as a measure to avoid foundation cracking), so foundation problems are a common occurrence.

Thankfully my tenants are all responsible for their own utilities.I should add: with the relative humidity about 20%, 68 degrees feels MUCH cooler than it does in other parts of the country. 

I live in the south, so between high moisture/humidity and weather, moisture is present.  

We are a humid climate and rot is also a factor. 

The property is in WI so 80-90 degree humid days for about 2 months out of the year, another 2 months are warm/hot but not as bad. 

In New Orleans the last thing I want is something else to make me hot and humid.

If you want something longer-lasting, cedar and redwood are great—they handle Houston’s humidity well, though redwood is pricier.

Definitely a very humid environment, especially near the coast, so expect to deal with all of the issues that come with high humidity - termites, bugs, mold/mildew, wood rot, etc.

Summers were ok but are extremely humid.
