Some potential drawbacks to keep in mind are:Additional closing and loan origination costs (two transactions/mortgages instead of one) - speak to your lender and title company about costsTwo insurance policies instead of one - probably close to double the insurance cost as compared to a duplex - get a quote from a good insurance agent and compareTwo sets of property taxes instead of oneThese certainly aren't deal killers, and the benefits noted above may outweigh the disadvantages.

The disadvantage is that it is one more person you need to notify/serve if things go south.

Capitalism is about trading what you create with your advantages for what others create with their advantages (that you are disadvantaged at).
