buying duplex or single-family home has become a popular way for investment, especially for tech workers in silicon valley recently. there are some major considerations when making the decision between duplex and single-family home investment.

return on investment of duplex versus single-family home
duplex can generate rental income from two units, providing higher cash flow and return on investment. however, single-family homes tend to appreciate faster in desirable neighborhoods. investors need to calculate capital gains for long term holding.
property management expenses for duplex and single-family
managing two rental units in a duplex requires more work than a single-family home. many investors hire property managers to handle leasing and maintenance, but this also cuts into returns.
financing costs of duplex versus single-family
duplexes may have higher mortgage rates than owner-occupied single-family homes. however, with two rents, it’s easier to qualify for financing. investors should shop multiple lenders and financing options.
future selling flexibility of duplex and single-family
single-family homes tend to attract more potential buyers down the road. a duplex limits the buyer pool more than a single-family house would. investors should factor in exit strategies.
in summary, duplex investment can generate higher rental income but single-family homes may appreciate faster. investors need to calculate cash flow, appreciation, expenses, financing and exit flexibility before deciding between the two. professional advice is highly recommended especially for first time investors.
