Knobs on the uppers-all doors, pulls on the lowers-mix of doors and drawers. Here's my reasoning: the pulls won't catch on my clothing or on the grandkids...and it's easier to put the child safety cabinet locks through the pulls. I don't know if either of those issues apply to you but our 5 visiting munchkins range in age from 12 months to 9 years so we needed to consider their safety in some of our decisions. I'm in the process of marking off the hole so DH and I can install the hardware tonight when he gets home...if I absolutely hate it I'll let you know. That's my 2-cents worth.

Can't tell for sure without the flower but the leaf shape would indicate one of the species clems.

We are often asked this question here and unfortunately there is no way to know which of the 100 possible varieties they are other than to say they appear to be cherry-sized and have dark green shoulders at this stage. And, since they are volunteers, they may not be any true variety but a hybrid throwback. However your plant is desperately in need of nutrients. Note the purple color of the veins and stems and the anemic green color of the leaves? Both are clear signs of nutrient deprivation and the need for feeding. Dave

There are enzymes that claim to neutralize pet odors from urine. Perhaps one of these was used. Realtors often use ozone generators to eliminate pet and cigarette odors before listing. Absence of odor can be explained. I suspect that if you were to use a wood floor scraper to remove some finish and wood off one of the spots in the foyer, you would get an odor. Nothing you've suggested as possible causes would make those concentrated spots on the floor, especially when the surrounding areas look to be completely unaffected. As I wrote before "Maybe there was a leaky pipe at some point but it didn't cause these stains that are textbook examples of pet stains.". Maybe there's a leaky roof. Maybe there's been leaky windows. These should all be investigated, but with 36 years doing only wood flooring, and being called in to look at all manner of issues, I'd say it's pretty clear to me that these are from pet stains. I disagree with GreenDesigns somewhat. I don't know the pricing of houses in the area but being an hour or so from DC must affect prices. It looks like a cool house and property. Paint color is a poor reason to reject a house since it's easy to change (and most people want to make it their own). The roof looks sketchy but not too hard to replace. The foyer floor would have to be completely replaced, painted or maybe stained really dark. The other floor areas could be evaluated to determine whether furnishing or rugs would hide some of the stains, patch if necessary and refinish. Good luck!
