My suggestion (and what I do) would be to continue using DynDNS, and create a subdomain for
home.example.com and make a
myhouse.dyndns.com (or whatever your DynDNS domain name is). This gives you the flexibility of using your own domain name with the ease of updating of DynDNS.
Personal example: (the .doesntexist.org address is my DynDNS address)
