I'm new to the real estate investment game and I'm a bit nervous about dipping my toes into unknown waters. 

@Shafi Noss Improving the land would be the simplest since there's already a driveway, electricity, and an old water well that needs to be jetted again.

Let’s start with CompliancePrompt:[1] You are an expert in the federal and state taxation of landlords owning rental property [you need to tell the AI what is expected].[2] I am a CPA, with expertise in taxation of real estate [unless you want a watered-down response, tell the AI that you want a granular response][3] Use IRAC format [This is used by attorneys.

Appears the guests may have left the faucet "on" when the pipes were frozen and when no water came out, forgot to turn it "off".What may have caused the overflow of the sink is maybe the drain lines were also frozen?

Water overflowing the sink, seems more plausible than some missing caulk.  

If they can't do that, keep shopping.This may require digging up the foundation, sealing it from the outside, and installing a french drain to keep water away from the walls.

If it can be used as a STR it's going to have septic, well water and need Starlink for internet.
