That's a nice section of Bolingbrook -- the price listed is the monthly RENTAL price. Be careful with the "historic section" of Bolingbrook -- high crime rate. Also, there was a recent stabbing at Bolingbrook High School.
RainEx should never be used indoors! It is not approved for indoor use and has not been tested for indoor human exposure to the chemicals in Rain-X. Also, CLR and vinegar WILL damage anodized hinges, fittings, or pulls on yoru glass shower doors. The only approved cleaner is Comet non-abrasive. You may also try the cream cleaner (CermaBrite) for glass cook tops for really tough deposits. Best practice is to squeege off the water after showerign to avoid mineral build-up.
Travertine was a huge fad that's run it's course.
Granite is a trend that may not last much longer. It's getting a bad rap because it stains in the kitchen areas and needs to be sealed every year. You might wish to look at Quartz (the look of granite but no staining and no sealing) or soap stone.
I havev both: Pergo in the family/rec-room and black walnut in the main "show" living room. Nothing beats the look of real wood and nothing beats the abuse Pergo will take. The natural black walnut has scratches and dents but the Pergo wears like iron. I woud suggest putting Travertine tile in the high traffic areas, hardwood in your formal dining/living rooms, and Pergo in your family/recreation rooms.
Go to a local home show and look for a floating click together ceramic floor. It is very easy to lay, doesn't need expensive underlayment adn will not crack! Cost is about $5 per sq. foot, which is about the same cost after you total the underlayment, thin set and tile for a conventional ceramic floor. All you do is snap the pieces together adn use their special flexable grout.
We used "The Shutter Hut" and were very pleased with the quality. Might want to do a Google search on them adn get an estimate.
Home Depot is like playing craps at the casino -- it's very hit or miss. Everything is subcontracted out and you have no idea who is going to show-up to do the work! We had a complete kitchen rehab throught Home Depot and the contractor who did the quartz counter tops did a great job but another Home Depot sub that did the cabinets was sloppy and did poor work. We complained to Home Depot and all they do is send the same guys back again and again to try to fix the problem with very limited suscess. If your doing a "flip" use Home Depot. If you want it done right use a local specialzed company that has been in business a long time. You might pay more but you are more likely to get quality work by craftsman.
I would not recommend a retail super store garage floor paint, as you will not get the wear quality needed. Go one step up to a "micro overlay concrete" process. Just do a Google search on those key words and you will have a prodoct that will look like tile, stone or solid color and will not scratch or lift like garage floor paint. My 2 cents.
