  We present the host galaxies of four apparently non-repeating fast radio
bursts (FRBs), FRBs 20181223C, 20190418A, 20191220A, and 20190425A, reported in
the first Canadian Hydrogen Intensity Mapping Experiment (CHIME/FRB) catalog.
Our selection of these FRBs is based on a planned hypothesis testing framework
where we search all CHIME/FRB Catalog-1 events that have low extragalactic
dispersion measure (< 100 pc cm$^{-3}$), with high Galactic latitude (|b| >
10$\deg$) and saved baseband data. We associate the selected FRBs to galaxies
with moderate to high star-formation rates located at redshifts between 0.027
and 0.071. We also search for possible multi-messenger counterparts, including
persistent compact radio and gravitational wave (GW) sources, and find none.
Utilizing the four FRB hosts from this study along with the hosts of 14
published local Universe FRBs (z < 0.1) with robust host association, we
conduct an FRB host demographics analysis. We find all 18 local Universe FRB
hosts in our sample to be spirals (or late-type galaxies), including the host
of FRB 20220509G, which was previously reported to be elliptical. Using this
observation, we scrutinize proposed FRB source formation channels and argue
that core-collapse supernovae are likely the dominant channel to form FRB
progenitors. Moreover, we infer no significant difference in the host
properties of repeating and apparently non-repeating FRBs in our local Universe
FRB host sample. Finally, we find the burst rates of these four apparently
non-repeating FRBs to be consistent with those of the sample of localized
repeating FRBs observed by CHIME/FRB. Therefore, we encourage further
monitoring of these FRBs with more sensitive radio telescopes.
