If you are single or married with a small child, buying a duplex or 4plex should work well.  

Hi all - Looking to get my property in Denver rezoned to allow for a duplex.

Purchase price: $290,000 Sale price: $72,500 Two-story duplex, each unit with 2BR/1BA.

Quote from @Khaled El Dorry: I have a portfolio of 3 SFH's (2 in Jax and 1 in ocala) and 1 duplex in port charlotte (never flooded or damaged due to hurricanes) that have done very well for me.  

I own a duplex in San Francico (Potrero hill).

I am looking into buying a duplex in Hyatt Park and wanted to get some advice on what contractors/suppliers I could contact that have investor friendly pricing for kitchen cabinets, countertops, and bathroom vanities.

@Dillon Onsager Where's the duplex located?

You can always do a two unit duplex for rentals that have two floors. 1 floor per unit.

When it comes to real estate, here's a general list of eligible assets and their depreciable lifespans that you should know: Residential Rental Property = 27.5 yearsThis includes any building or structure where 80% or more of its gross rental income is from residential units.That means:- Apartment buildings- Single-family rental homes- Duplexes, triplexes, and quadplexes- Mobile homes (used for residential rental)- Any kind of residential lodging facility where the primary purpose is long-term rentalCommercial Property = 39 yearsThis includes non-residential properties like:-Office buildings-Retail stores and shopping centers-Warehouses-Industrial complexes-Hotels and motels that do not qualify as residential rental propertyLand Improvements = 15 yearsThese include sidewalks, roads, fencing, some landscaping, and parking lots that are separate from the building.Personal Property = 5 or 7 yearsPersonal property used in a rental activity usually has a 5 or 7-year life.This includes most furniture, appliances, carpeting and various machinery.Qualified Improvement Property (QIP) = 15 yearsGenerally, this includes any improvements made to the interior of a non-residential building after the building was placed in service, excluding elevators, enlargements, and the internal structural framework.Computers and Related Peripheral Equipment = 5 yearsVehicles = 5 yearsNote that the land itself is not depreciable.

Since your properties have significant equity and low interest rates, you could consider refinancing just enough to maintain strong cash flow.House Hacking:Consider purchasing a duplex, triplex, or fourplex in San Diego.
