There are a lot of sites that give good advice for getting started on preparing, for any number of scenarios. All you need do is search and read.
Your request is really broad and whole books have been written on the subject. Gonna need to get more specific as to what you are asking, anon.
You can even avoid dealing with the hassles of being a landlord by hiring a property management company to manage your properties for you. If not, I do suggest you invest in a few hours with a lawyer to make sure you understand the legalities of renting in your state, and set up leases and an escrow account for deposits, and know how to legally evict, and so on.

Home gathered eggs last a while on the counter, maybe a week, depending on temperature in the house. Hard boil eggs that are getting older and then pickle them to last longer. You can seal eggs with the isinglass solution or you can coat them with butter when fresh out the butt - the Irish way to make them last longer. Any kind of oil or fat works, but the eggs will pick up the taste so butter is yummy. You can also dehydrate eggs at home, although the government says it'll kill you.
