So we replaced the larger old Farm House looking inherited mailbox with a skinny metal one from HD.

I have never used them nor installed them, but my first thought was the same as @Brian Burke, you may save money on the install but in the long run with maintenance and possibility of hazards - that alone would steer me away from them, i like to sleep at night - i think you are better off venting once and forgetting, it will be done. btw, they are $15 at HD. and this is what theirs look like and how it works, the bottom of the container is filled with water, the lint is held by the water when it is forced in and then has to be cleaned and refilled after each use.

@Jennifer Marshall, look into Wilsonart HD laminate.

Depending on how much tile/flooring you need, I would check out Lowes and HD for their discontinued stock or whatever they have on sale.

I can literally not go to HD or Lowe's for years except for new larger scale rehabs. 

Lowes and HD have a policy that will cut the lowest price by 5%.

Yes, Home Depot has a bid room for Pro accounts and anything over I believe $2500 can go through the bid room.We are picking finishes for a 284 unit deal we are closing in a few weeks and looking at ordering via HD Supply.Some items we may source directly from the manufacturer in China.

If you store locally, get a terabyte external HD, and a 256G SSD.

It's not theoretically all that difficult to do yourself with a 60-buck trim coil from HD and some homemade shaping aids made out of clamps and dimensional lumber, but it's not a typical DIY thing.

@Josiah McGinnisNo, dont let him do it or arrange to have it done.If you feel the need, $89 @ HD and an hour of your time to install it will get you a happy tenant, a new efficient toilet (installed properly in your property) and him not asking to do future repairs himself.
