Hello and welcome,
It sounds like you live in a pretty standard suburban residential neighborhood, with many SFPRP (single family private residential properties) and not much else. I think many people have found it hard to find eligible POIs to nominate in these areas, and that’s due to the design of these neighborhoods being mainly SFPRP and not much else. And if there is anything that is on SFPFP, those are ineligible.
Even though this talks about rural areas, it can be helpful for all areas, so you may want to check it out: Tips for Rural Nominators
I’d also recommend checking out the Criteria Clarification Collection to know what may or may not be eligible.
And yes, neighborhoods in different parts of the world may have more multi-family homes, and those may have eligible POIs. The “dream” of a house with a yard for one family isn’t the same in other countries as it is in the US.
