You're going to have trouble mitigating this noise without a dead air space between the joists/rafters above and your ceiling finish below.

I'm considering buying a property in a highly desirable beach community on Cape Cod. The owner has the property listed at 500 ft.² more than it actually is because they are counting an attic that has three mattresses ...

Your wiring could be knob & tube and/or aluminum.

Question, if I have my str in an LLC should I list it with air bnb under my name or under the llc? 

THe last owner hid knob and tube wiring in the walls; this increased the electrical from $2500 to almost $6000 since we how have to rewire all the electrical in the house.

In hindsight, I should have stocked up on ACs.In 2025, new air conditioning systems will no longer use the older R-410A refrigerant due to environmental regulations.

I want to look into getting into real estate investing and perhaps buy a townhome and start out with a 3 or 4 bedroom that I could do an Air BNB with and then eventually have it all Air BNB as I build a portfolio? 

There weren't any really with this one other than us hoping and praying we would target a military family with the town being so small, but having an Air Force base close by.  

If his high usage is during the summer you probably need better air vents in your roof.  

We ended up replacing most of the wiring in the place as some was knob and tube, and some was ungrounded and not up to current code and safety.
