The tree is in a neighbor's garden. Do I have a right to ask for it’s removal?
Your concern is legitimate, horse-chestnuts are large growing trees, and you certainly have a right to discuss it with the tree owner. But to ask for removal may be premature. I would suggest that before you make demands, have a friendly, neighborly conversation and ask for cooperation in determining if the tree roots are in fact presenting risk of property damage. A consulting arborist or construction/structural engineer could provide professional evaluation. They may dig down to expose roots and the home foundation to determine specifics of any intrusion. The potential for damage to the bungalow structure depends on the type of foundation and how substantial it is. If it's pier and beam construction and elevated flooring, then the roots may not be a problem at this time. If there are major lateral roots directed against or under a solid concrete foundation, it should be assessed for risk potential, and if any measures could be used to reduce the risk, like root pruning and root barrier installation.
I have three giant horse chestnut trees in my yard. None of the rakes I have will pick the horse chestnuts up or move them much at all. We end up having to pick them up with our hands, and that will be a lifetime project. I'm wondering if a thatch rake would work better.
It takes a combination of raking with a hard garden rake into piles and then shoveling into buckets with a small scoop shovel or placing by hand into buckets.

In addition to curling of the lower leaves, the second seedling has brownish colored leaves. Are these serious problems? I am in Connecticut now but taking these with me when I return to East Texas, will they survive?
These trees can be pretty drought tolerant, and generally the soil should be allowed to dry almost completely between watering in container.
You can try watering in a solution of 1 tablespoon hydrogen peroxide with 1 cup water once the soil is almost completely dry. This will help stop the infection. Old growth will not recover, but new growth should remain green. Once the treatment has been applied, then wait until the soil is dry again, and do the treatment once more.

This is likely Chestnut Blight. There is no cure, unfortunately, and management is often not possible.
It looks to be a Chinese chestnut, or hybrid. This is more resistant to the disease, but once it takes hold there is no cure.
