I think he was saying that the cheaper ducts that go in the walls have a layer of insulation and plastic around them thats why they don't condensate.  

TOOLS REQUIRED-Post hole digger, long handled pointed shovel, baulk-line, measurement tape, power tool with plastic cutting blade, extension cords, concrete combination tub, 4' level.

So, be aware of that - once you put those signs out:1) People will take them - often other investors or neighbors that don't want plastic signs in their area, and2) Code enforcement could fine you.  

To really get on their good side, you can also provide a gas grill for cooking out with patio furniture.

Hello,I have a 2650 square foot, two-story home (4 bedrooms/two bath) that needs a complete remodel and upgrade, inside and out, plus a new patio cover.

If the numbers are attractive, what would you do - filling it or "flip" a pool (maybe the patio walkways, bricks, and fencing around it?) 

My occupation is as a scientist in the plastics industry with 21 patents issued under my name; however, my business is real estate investing.

For example, if I were to remove a window and put in a new patio door and it cost me $450 I could have it be a expense even though it would be clearly a capital expenditure.

Over Improving would be fixing/renovating a property to a point were you will not recoup that capital investment because the neighborhood comparables will not support a value that high.An extreme example would be installing a $100,000 in ground swimming pool and patio in a home in a neighborhood where the homes typically seller for $85,000.

Found that the cement on a side patio sloped significantly towards the house which caused some leaking that we didn't see and a hazard in winter with freezing over.
