The process is the same. Be aware however that NACA can only be used for buying a completed home and cannot be used for custom built homes as they require a construction loan. A construction loan allows the builder to access funds during the construction process rather than provide their own funding for construction.
Once the home is completed though, a NACA loan can be used to pay off the construction loan and become the primary mortgage on the property.
Likewise, a NACA loan can be used to buy a home in a pre-planned community, even if the home has yet to be built, as long as the builder’s funding for the construction comes from someplace other than the NACA mortgage.
