A good friend of mine rents his condo in downtown San Diego and does very well.

Some other RE options include notes, syndication, NNN, REIT, a wide variety of commercial non residential (Mobile home parks (residential, but not traditional residential), industrial, storage units, retail space, office space), development, land speculation, mineral rights (My first home run was in mineral rights), etc. 

The minerals in the water eat up galvanized supply line and cast iron waste lines, so units with copper and plastic will avoid a lot of expensive repairs. 

Cuz then they'll need to be oiled with mineral oil. 

When you go to Las Vegas, the very highest mountain just before you get to Las Vegas has a  large lake, about 500 x 500 feet where miners dug down about 300 feet into the ground for gold or silver and then underground water filled the hole to about 9 feet deep with fresh water that constantly flows through the lake.

Our clients tend to have bad experience with hard water/mineral stains in the bathrooms we renovate, so we've made it a practice to deal with the additional cost and minor headaches of epoxy grout for all client work, as it improves customer satisfaction, and helps reduce the number of service calls for return work.

Additional investment options that you may want to consider are bare land or oil & gas mineral rights. 

Most of the alts on our platform (self storage, MF, student housing, oil & gas mineral rights), pay about 10-15% cash flow annualized, paid monthly, with about 10-19% IRRs at the end of the 2-6 year hold periods. 

Hey Jack,You might consider investing in Oil and Gas Mineral Right Royalty funds with that 160k. 

My experience has been good and the guy running mine really knows what he is doing.
