Do you have a thick or heavy accent that makes it hard to understand you?  

If not, maybe buy some thick area rugs.I have to say, I find it especially weird it is the unit below his. 

I'm buying my first property with no agents involved and I just picked up a thick stacks of papers from the escrow office that I need to sign.

Hardwood floors are durable and if you have 'em already and they're usable, by all means, keep them.Not having anything done to them in 30 years could be a plus if the wear layer is still thick enough to allow for it to be sanded.  

Flooring I would look at the really thick high quality laminate planks (you can find on sale too for cheap) and most people will not be able to tell the difference between that and hardwood. 

Rubber cement and router needed. 2nd house I did a tile counter but with thick grout lines.

When it's Saturday AM and I want to sleep in till noon, I still miss my thick black sheets and dislike my wife's "but it looks nice" option!

I am also thick in the world of real estate here in Wichita Falls in almost all aspects.

Sometimes the surprises are under the carpet...There was a 4" thick concrete slab over that hole that Hubby had to bust up with a sledge.

Being a landlord mean being thick skinned, being able to be objective, and to some degree having to be 'the bad guy" sometimes - not everyone is comfortable taking on these roles - best of luck to you - I'm looking forward to seeing how all of this turns out.
