I don’t think the one in your photo will rent for $1400 month, BTW. It doesn’t appear have the three top selling points going for it … that is, location, location and location. I would venture an educated guess that it will rent (on a bright, sunny, snowy day) for $225 mo (incl propane).
If it’s any consolation, those traincar-type condos which we discussed here . . .
are not only present in MM/SH/SV. They are ALSO present in ChulaV (91915) and Santee … to my knowledge. This style of condo may be present in other SD County areas as well. They lend themselves well to four-units-per-zero-lot-line-PUDS and other various and sundry developments whose builders sought to squeeze 20+ units out of ONE acre of land.
