We can't afford WiFi or a Security System (which I think would add a lot of value).
I have been working on improving our reputation and curb-appeal to make us more desirable/valuable.
I don't have a pool, clubhouse, or anything, yet I'm 100% occupied.
I'm 100% recommended on ApartmentRatings.Com and have a very clean property.
My tight rules on vehicles helps, too. No damage, no missing hubcaps, no obscence or offensive paint finishes, etc.
Drive through your competition and make your curb appeal better.
That adds value, too.
