Do you disagree with that characterization?
I didn't say its only an investment, though maybe you meant say "only a good investment", if you get it through a government backed loan but I do think it makes a lot more sense when you rely on government subsidies which can help you get the down payment, allows you to write off the interest on your taxes, and guarantees a 30 year fixed interest mortgage at below market rates.
The proportion of FHA and USDA loans differs years to year but its about 15%-20% which is not an insignificant figure. The figure is higher when you look at those loans for primary residences, as opposed to investment properties whose loans aren't backed by the government, and specifically first time homebuyers. I'm seeing differing figures but
a report from last year suggests about ~45% of first lien mortgages are from GSEs
That's not an insignificant figure. In general first time homebuyers and those looking for a primary residence are more likely to rely on GSEs for mortgages given investment properties don't qualify.
